EUROPE

* Novartis, Glaxo vaccines earlier won approval

NEW YORK, Oct 7 (Reuters) - The European Commission has approved Baxter International Inc's (BAX.N) Celvapan vaccine against H1N1 flu, the company said on Wednesday.

The positive ruling was expected after the European Medicines Agency recommended the vaccine last week. European regulators earlier gave a green light to the first H1N1 swine flu vaccines from GlaxoSmithKline (GSK.L) and Novartis (NOVN.VX).

Governments have been scrambling for vaccines to target the new H1N1 flu strain, ahead of a feared second wave of infection.

Baxter said initial quantities of its vaccine have already been delivered to a number of countries, including Britain and Ireland, for use in their national vaccination programs.

Last week the European Medicines Agency (EMEA) gave their recommendation for two vaccines to combat the H1N1 or swine flu that is facing the world. This recommendation leads the way for mass vaccine programs to begin as soon as they are approved which could happen as early as next week. Government and healthcare professionals have been worried about dealing with a second outbreak that could begin as we approach winter so the entire process has been expedited to be better prepared.

The EMEA gave the nod to the two new drugs which are manufactured by GlaxoSmithKline and Novartis. The vaccines are called Pandermix and Focetria.
A third vaccine by Baxter did not pass the committees approval process but it is still being considered.

The World Health Organization (WHO) announced last week that there will only be enough vaccines produced by drug makers to cover about half the planet – roughly 3 million doses a year. It will be determined who is most at risk and who would be top priority to receive the vaccines.

It is also being decided whether one dose or two shots will do the trick. The WHO feels that one vaccine will be effective in treating the pandemic but the EMEA thinks that some people should receive one vaccine and then get another dose after three weeks.

The vaccines are considered safe to use and both the new versions contain adjuvants which are substances that build up the immune system so they require less of the active ingredient, the antigen, in each dose.

The Glaxo vaccine has only 3.75 micrograms of the antigen in each dose while the Novartis shot has almost twice that amount – 7.5 micrograms. Non-adjuvanted vaccines normally carry 15 micrograms.

While richer nations have enough money to ensure that they can obtain enough vaccines for their people, poorer countries have to rely on the generosity of others. In the beginning of September, the Food and Drug Administration (FDA) approved vaccines to fight the H1N1 swine flu from four drug companies: AstraZeneca’s MedImmune division, Sanofi-Aventis, CSL and Novartis.

According to the WHO, an initial distribution of the more than 300 million doses, which were donated by other countries to over 90 countries in need, will begin sometime in November.

Symptoms of the swine flu include headache, sore throat, runny nose, loss of appetite, aching muscles, diarrhea or vomiting and unusual feelings of fatigue. One of the first signs of the flu is a fever so officials suggest you keep a thermometer on hand and know how to determine your temperature.

You should contact your physician if you are someone who would be considered at risk, such as someone who is pregnant, has a compromised immune systems and children under the age of one who are already ill. Contact your physician if your symptoms get worse suddenly or they do not appear to be going away after a week, five days for small children.

TORONTO - CANADA


The window of opportunity for accelerating the pandemic flu vaccination program in Canada may be starting to close, unless word of a change of plans comes soon, experts suggested Tuesday.

But despite pressure to speed up the start of the program, the country's chief public health officer continued to insist that the projected start date of early November is still the target.

The early November start will allow Health Canada to follow the regulatory process it set out for approving the pandemic vaccine, Dr. David Butler-Jones said Tuesday.

Butler-Jones had recently said that if the risks of waiting to November started to outweigh the benefits of following the established regulatory pathway, the vaccination program could be brought forward a bit.

"(But) we're now into October ... (and) we're not seeing any of those conditions being met," Butler-Jones said in an interview with The Canadian Press.

"So at this point I'm anticipating that the regular regulatory process with a target that we can start immunizing by the first week of November, that that should all roll out fine."

With that point approaching, provinces and territories need to know when they will start taking possession of vaccine so they can finalize plans for what public health officials hope will be the biggest mass vaccination effort in the country's history.

Plans are currently set for clinics to take place in November. Those plans cannot be changed on a dime. Dr. Perry Kendall, British Columbia's chief medical officer of health, said provinces and territories would need at least a week or two of notice to get clinics organized and staffed if the start date is going to change.

"If vaccine were available today, we'd still need time to train the delivery system for this specific vaccine, arrange clinics, advertise, review consent forms, pre-position vaccine supplies, ensure labeling and mixing (is) understood by all, etc.," Kendall said in an email.

Given that the first week of November is just three-and-a-half weeks away, unless word of a change comes soon there may be little gain from moving up the program start.

Meanwhile, Canadian TV sets tuned to U.S. TV channels are seeing images of Americans already being immunized against the virus. The U.S. effort began Monday, with 2.4 million doses of a nasal spray vaccine expected to be shipped to states by the end of this week. That vaccine, FluMist, is not currently licensed in Canada. Injectable vaccine supplies will start to flow in the U.S. next week.

But where the U.S. is buying its pandemic vaccine from five suppliers, Canada has purchased its 50.4 million doses from a single producer, GlaxoSmithKline. The U.K.-based pharmaceutical giant has a flu vaccine production facility in Ste-Foy, Que.

GSK's European plant, based in Dresden, Germany, is already shipping vaccine. But it started making the pandemic product sooner than the Quebec facility, a senior GSK executive said in a media briefing on Monday.

Dr. Thomas Breuer explained the European production facility has two buildings and was able to start making pandemic vaccine in one while finishing its seasonal flu product in the other. The Quebec plant has only one building, so it had to finish the seasonal shots before starting on the pandemic product.

"It is currently envisioned that product will come out of the Canadian facility end of October, beginning November," said Breuer, a senior vice-president and chief medical officer for GSK.

But Dresden's quicker start will help speed vaccine approval here, Butler-Jones said.

Data generated by GSK in clinical trials in Europe will be used to approve the Canadian vaccine, he said. Health Canada will use those data to assess the safety and immunogenicity of the vaccine - in other words, its ability to induce a protective response.

"It's the same vaccine. It's not made in the same plant but all the processes and everything are the same," Butler-Jones said.

"So there's no need to wait for the Canadian confirmatory data which will come later. Because it's exactly the same process, the same vaccine from the same company."

CHINA

H1N1 Vaccine is Launched in CHINA, and the country braces for impact

Parents waiting to pick up their children from Beijing's Sanlitun Primary School are greeted by a new sign, "If your child has any kind of a temperature don't bring them to school tomorrow. Keep them at home."

Parent Xuan Yen said that her daughter's treatment at school seems more like the treatment she would get at a hospital. "Every day the school takes my daughter's temperature twice a day and administers Chinese herbal medicine to keep the H1N1 virus away."

But the precautions are not just in the schools. China's population of 1.3 billion people makes up one-fifth of the world's population, and tens of millions of Chinese could get H1N1. So China is acting quickly to prevent such a disaster by releasing the world's first vaccine.

After a relatively unremarkable summer, China saw a spike of 1,600 cases in just three days last week. Sixty percent of China's cases were confirmed only in the last three weeks.

The country's health minister Chen Zhu, unusually silent about the threat, suddenly stated the obvious after 14,000 cases of H1N1 cases were confirmed nationally.

No independent organization has declared the Chinese vaccine safe, but the vaccine maker has marketed it to the world as of a "quality and standard not just to suit the Chinese but also the international level." Across the board, the Chinese government is urging its people to be vigilant. Chinese airports are on high alert — arriving travelers have their temperatures scanned as airport workers wear masks at all airports, and a bizarre in-flight video advises passengers to be vigilant, both during and after their trip. The message states, "H1N1 is dangerous. Eat soup. And open your windows at home, not on the plane, and keep circulating fresh air to reduce germs."

Over the summer, thousands of Americans were quarantined after arriving to China simply because someone on board their plane had a slightly elevated temperature. In the last month the American Embassy says that has tapered off, because the Chinese realize the threat is no longer from the outside — it's inside the country. Cases of H1N1 have been diagnosed in every province.

ISTANBUL


Rich countries should make more vaccine available to poorer nations where the H1N1 virus is starting to hit, U.N. health officials said on Sunday.

They said increased readiness for swine flu was needed in developing countries with weaker medical systems and with large, young populations, who are most vulnerable to the disease.

"We may well see a different pattern of impact once this virus starts to take off and those explosive outbreaks occur in some of the poorer communities in the world," said Julie Hall, an infections disease expert at the World Health Organization, a U.N. agency.

The WHO, which declared H1N1 a global pandemic in June, says a third of the world's population of nearly 7 billion people could catch it.

Some countries, such as the United States, Brazil and France, have agreed to make 10 percent of their national vaccine stockpile available to developing countries. Manufacturers have also donated about 150 million doses of vaccine.

More is needed, said David Nabarro, the U.N. coordinator for fighting new emerging flu varieties.

"The challenge during the next few weeks is to build up the solidarity between wealthy nations and poor nations to ensure that adequate vaccine is made available," he said.

September and October are usually just the start of flu season in the northern hemisphere, but there are signs of a second H1N1 wave after it first flared this year, Hall said.

"Already we are seeing the U.S., many European countries, Japan and Mexico reporting over the past few weeks a sudden increase in cases," she said.

As of September 20, swine flu had killed 3,917 people in 191 countries since being identified in April, the WHO has said.

TOKYO - JAPAN

The Japanese government said on Tuesday it would buy enough H1N1 flu vaccine from British drug maker GlaxoSmithKline (GSK.L) and Switzerland's Novartis (NOVN.VX) to treat nearly 50 million people.

The government said last week it would secure enough to treat a total of 77 million people by the end of March next year, with Japanese makers producing enough vaccine to treat 27 million people. It added that it would start importing vaccine from around the end of December or January.

Experts predict that a third of the global population - 2 billion people - will eventually be infected with H1N1, which was first seen in March in California and Mexico.

The World Health Organization said in late August that the new H1N1 swine flu had reached epidemic levels in Japan, signalling the early start to what may be a long influenza season this year. [ID:nN28366771]

The health ministry said in a statement on Tuesday that the government had reached a deal with the two foreign makers, with a contract totalling 112.6 billion yen ($1.26 billion). It did not specify how much it would buy from each of the two companies.

A Japanese newspaper, the Asahi Shimbum, reported last month that the government would spend about a total of 100 billion yen to buy enough vaccine for 35 million people from GlaxoSmithKline and for another 12 million people from Novartis. [ID:nLB571112]

Talks on the purchases have been delayed due to liability concerns, with the foreign makers asking to get immunity from responsibility in case of any side effects from vaccination.

The government now plans to submit a bill to parliament so that it could pay compensation to patients who suffer from any side effects of imported vaccine or pay lawsuit-related costs on behalf of foreign makers.

Tokyo, which has set aside 138 billion yen in budgetary spending to buy H1N1 flu vaccines, plans to start administering vaccines from the week of Oct. 19, with priority given to medical staff, high risk groups such as children, pregnant women and those with underlying medical problems, including diabetes and respiratory illnesses.

At home, four Japanese makers will produce H1N1 flu vaccine: Denka Seiken Co., Ltd, the Research Foundation for Microbial Diseases of Osaka University, the Kitasato Institute, and Kaketsuken (The Chemo-Sero-Therapeutic Research Institute).

Three of them will start shipping the H1N1 flu vaccine from Friday, the health ministry said, to be ready for vaccination staring later this month. In Japan, one will need to pay a fixed cost of 6,150 yen ($69.06) to get two vaccination shots. ($1=89.04 Yen)

Egyptian Travel Case Below


With the global concern over the H1N1 swine flu virus rising, some tourists are finding themselves inside a quarantine cell as their first sightseeing experience. Egypt is attempting to curb the virus with strict measures, but its policies and quarantine system have some questioning their efficiency. With about 900 confirmed cases of swine flu, the Egyptian government has taken a number of controversial steps to fight the spread of the virus, including the closure of all schools until October 3.

Last month, the government banned elderly Egyptians and those younger than 25 from traveling to Mecca, Saudi Arabia for their Umrah or lesser pilgrimage. Director of the Michigan Center for Public Health Preparedness Dr. JoLynn Montgomery understands the Egyptian government's concern; Cairo is a densely populated city of about 20 million and millions of pilgrims from around the world travel to Mecca. "Certainly time in very crowded areas will result in cases of influenza right now," Dr. Montgomery. "I do know that Mecca is a big calling and a big issue and not being allowed to go is obviously a big issue for them [Muslims], but those locations have proved to be a big opportunity for spreading disease."

But some health experts and organizations like the World Health Organization have not always viewed Egyptian government measures as reasonable. Earlier this year, the government ordered the killing of all pigs in Egypt despite WHO officials calling it a misguided attempt to combat the H1N1 virus.

Then in June, the Egyptian government quarantined about 150 people residing in an American University of Cairo dormitory for a week after two students tested positive for the virus. In Egypt, the policy is to quarantine those suspected of having swine flu. And as this reporter experienced firsthand, anyone is a suspect.

Out of the approximately 250 passengers aboard a recent flight from New York, I was the one person ushered to the side while an airport employee handed me a disposable thermometer. They told me I had a fever and would have to wear a white hospital mask. Feeling completely healthy, this was definitely not the warm welcome to Egypt I had in mind.

A young woman wearing a headscarf and over sized sunglasses introduced herself as Dr. Germine. She said I would have to go to a hospital where they would "investigate" if I had swine flu. With my navy blue American passport between her fingers, there seemed to be not much of a choice. The American Embassy, like many others, cannot directly intervene if a private citizen is held upon arrival in a foreign country.

But chief of American Citizens Services in Cairo Yolanda Parra says citizens do have rights.

"If you find yourself in a situation that you're not comfortable with or you have questions about definitely reach out to your embassy right away," said Yolanda Parra. "You can ask anyone at that medical facility that you please want to speak to your embassy and they will comply."

At the hospital, Dr. Germine announced that I would have to pay $300 for a throat swab test and 24-hour observation. I refused to pay. The charge then dropped to $100 and I refused again. After a call to the American embassy, the charge was dropped.

Parra says that it is not standard procedure for governments to charge those quarantined but it can depend on the procedure.
"Each case is different," she said. "We on your behalf make sure that the payments that they're asking for are valid but in that particular case we investigated and the person didn't have to pay anything."

The quarantine area where the throat swab test was processed was, surprisingly, filled with energy. Muffled voices of children carried across the courtyard as they played soccer with surgical masks on. But with a closer look, it was clear many patients were coughing and moving sluggishly nearby. People apparently infected with H1N1 interacted with those under observation.
The WHO does not recommend the mixing of those infected and those under observation. It says it's critical for national authorities to distance patients and avoid crowding. Dr. Montgomery says it's the government's responsibility to uphold these quarantine standards.

"Whether it's mandatory or not, they're playing a role in protecting the rest of us by doing that and so there should be respect and care given to people who are in those situations," said Dr. Montgomery.

The Egyptian Ministry of Health has recently announced that when schools re-open in October, they will be equipped with quarantine rooms.

Keeping up with current closings and regulations is highly recommended in all third world countries, and when traveling, proof of vaccinations and immunization records are very helpful.

FROM GSK - LEADING GLOBAL PRODUCER OF VACCINE


GSK has agreed another 22 government orders for its adjuvanted swine-flu vaccine - an extra 149 million doses on top of its previous agreements.

The new deals bring the total orders GSK has received to 440 million doses, making it one of the major global suppliers of H1N1 vaccine.

GSK says it is committed to supporting governments and health authorities around the world respond to the pandemic (H1N1) 2009 influenza strain.

In early August, it confirmed that it had contracts in place to supply 291 million doses of the vaccine and had a variety of agreements in place with the US government to supply pandemic products worth $250 million.

Since then, another 22 orders have been agreed to supply a further 149 million doses of the vaccine, and discussions continue with governments for further supplies.

GSK is using adjuvant technology, which boosts the potency of antigen, meaning the same volume of vaccine can be split into more doses.

Novartis is also using this mechanism on its own vaccine, though other suppliers such as Baxter and Sanofi Pasteur are not.

GSK, along with Novartis, has seen its jabs approved by the European regulator and the company says first supplies of its vaccine are being shipped to governments this week. Further shipments of the vaccine will be delivered in both the fourth quarter of 2009 and the first half of 2010.

Deliveries are contingent on a number of factors including government import and export regulations, regulatory and packaging approvals, and the testing required by reference laboratories.

GSK said it would continue to provide regular updates to governments relating to delivery schedules to support them in planning their vaccination programes.

MILLIONS AT RISK IN CHINA

BEIJING — Tens of millions of people could be infected with swine flu in China in the coming months, a health ministry official said Friday, adding that fatalities would be "unavoidable".

The world's most populous nation, at 1.3 billion, has so far reported nearly 7,000 cases of A(H1N1) influenza but no deaths. It soon plans to launch a nationwide vaccination programme to prevent mass outbreaks of the virus.

"According to expert estimates, our nation during the autumn season might have several tens of millions infected with A(H1N1)," Liang Wannian, deputy director of the ministry's health emergency office, told a press conference.

Liang said of that total, "half of them could experience clinical symptoms, several millions will seek medical help, and serious cases and fatalities will be unavoidable."

The spread of A(H1N1) influenza in China has gathered pace as the autumn months approach, Liang said, with more than half of the nation's nearly 7,000 cases detected between August 24 and September 10.

Of those cases, nearly 95 percent were homegrown, whereas the vast majority of cases reported from June to August originated abroad, he said.

"The situation we face is not optimistic," Liang said, noting that the virus had been found in all of China's 31 provinces and regions.

"We are facing severe challenges in our prevention and control work."

The World Health Organization (WHO) said last week that more than 2,800 people had so far died around the globe from swine flu. The virus has been detected in nearly every country.

The UN health body says China will be among the first in the world to launch a mass vaccination programme. The government has said it plans to vaccinate 65 million people, or five percent of the total population, before year's end.

"What we must work to prevent is a peak explosion of infections in a short period of time -- if this happens, it will be very dangerous," Liang said.

"If we see a large number of people infected in a short period of time, then a lot of people are going to seek medical help and our health system will not be able to handle this."

The State Council, or cabinet, on Thursday issued new regulations on handling A(H1N1) outbreaks, ordering the ministries of health and education, and the food and drug administration to coordinate prevention and control.

Such efforts will focus on schools as China has witnessed more than 200 "large-scale" outbreaks of swine flu since June, with over 85 percent of them occurring in schools or at school-related activities, Liang said.

The State Food and Drug Administration has granted approval to Beijing-based Sinovac to mass produce its one-dose swine flu vaccine, and is considering applications from other manufacturers, SFDA spokeswoman Yan Jiangying said.

The administration is closely monitoring potential side-effects of vaccinations, and putting in place a procedure to halt the programme should side-effects prove severe or production quality prove faulty, she added.

"We will begin emergency inoculations in an active, stable and orderly manner," with priority given to certain groups and in accordance with local outbreak conditions, Liang said, noting that vaccinations would be free.

Health Minister Chen Zhu said earlier this week that priority would be given to soldiers, police, children aged five to 19, those with chronic heart and lung diseases, medical workers, quarantine officials, and those working in the railway and aviation sectors.

People participating in the festivities to mark the 60th anniversary of the founding of communist China on October 1 will also be given priority.

PREPARING FOR THE SECOND WAVE

28 AUGUST 2009 | GENEVA --

Monitoring of outbreaks from different parts of the world provides sufficient information to make some tentative conclusions about how the influenza pandemic might evolve in the coming months.

WHO is advising countries in the northern hemisphere to prepare for a second wave of pandemic spread. Countries with tropical climates, where the pandemic virus arrived later than elsewhere, also need to prepare for an increasing number of cases.

Countries in temperate parts of the southern hemisphere should remain vigilant. As experience has shown, localized “hot spots” of increasing transmission can continue to occur even when the pandemic has peaked at the national level.

H1N1 now the dominant virus strain

Evidence from multiple outbreak sites demonstrates that the H1N1 pandemic virus has rapidly established itself and is now the dominant influenza strain in most parts of the world. The pandemic will persist in the coming months as the virus continues to move through susceptible populations.

Close monitoring of viruses by a WHO network of laboratories shows that viruses from all outbreaks remain virtually identical. Studies have detected no signs that the virus has mutated to a more virulent or lethal form.

Likewise, the clinical picture of pandemic influenza is largely consistent across all countries. The overwhelming majority of patients continue to experience mild illness. Although the virus can cause very severe and fatal illness, also in young and healthy people, the number of such cases remains small.

Large populations susceptible to infection

While these trends are encouraging, large numbers of people in all countries remain susceptible to infection. Even if the current pattern of usually mild illness continues, the impact of the pandemic during the second wave could worsen as larger numbers of people become infected.

Larger numbers of severely ill patients requiring intensive care are likely to be the most urgent burden on health services, creating pressures that could overwhelm intensive care units and possibly disrupt the provision of care for other diseases.

Monitoring for drug resistance

At present, only a handful of pandemic viruses resistant to oseltamivir have been detected worldwide, despite the administration of many millions of treatment courses of antiviral drugs. All of these cases have been extensively investigated, and no instances of onward transmission of drug-resistant virus have been documented to date. Intense monitoring continues, also through the WHO network of laboratories.

Not the same as seasonal influenza

Current evidence points to some important differences between patterns of illness reported during the pandemic and those seen during seasonal epidemics of influenza.

The age groups affected by the pandemic are generally younger. This is true for those most frequently infected, and especially so for those experiencing severe or fatal illness.

To date, most severe cases and deaths have occurred in adults under the age of 50 years, with deaths in the elderly comparatively rare. This age distribution is in stark contrast with seasonal influenza, where around 90% of severe and fatal cases occur in people 65 years of age or older.

Severe respiratory failure

Perhaps most significantly, clinicians from around the world are reporting a very severe form of disease, also in young and otherwise healthy people, which is rarely seen during seasonal influenza infections. In these patients, the virus directly infects the lung, causing severe respiratory failure. Saving these lives depends on highly specialized and demanding care in intensive care units, usually with long and costly stays.

During the winter season in the southern hemisphere, several countries have viewed the need for intensive care as the greatest burden on health services. Some cities in these countries report that nearly 15 percent of hospitalized cases have required intensive care.

Preparedness measures need to anticipate this increased demand on intensive care units, which could be overwhelmed by a sudden surge in the number of severe cases.

Vulnerable groups

An increased risk during pregnancy is now consistently well-documented across countries. This risk takes on added significance for a virus, like this one, that preferentially infects younger people.

Data continue to show that certain medical conditions increase the risk of severe and fatal illness. These include respiratory disease, notably asthma, cardiovascular disease, diabetes and immunosuppression.

When anticipating the impact of the pandemic as more people become infected, health officials need to be aware that many of these predisposing conditions have become much more widespread in recent decades, thus increasing the pool of vulnerable people.

Obesity, which is frequently present in severe and fatal cases, is now a global epidemic. WHO estimates that, worldwide, more than 230 million people suffer from asthma, and more than 220 million people have diabetes.

Moreover, conditions such as asthma and diabetes are not usually considered killer diseases, especially in children and young adults. Young deaths from such conditions, precipitated by infection with the H1N1 virus, can be another dimension of the pandemic’s impact.

Higher risk of hospitalization and death

Several early studies show a higher risk of hospitalization and death among certain subgroups, including minority groups and indigenous populations. In some studies, the risk in these groups is four to five times higher than in the general population.

Although the reasons are not fully understood, possible explanations include lower standards of living and poor overall health status, including a high prevalence of conditions such as asthma, diabetes and hypertension.

Implications for the developing world

Such findings are likely to have growing relevance as the pandemic gains ground in the developing world, where many millions of people live under deprived conditions and have multiple health problems, with little access to basic health care.

As much current data about the pandemic come from wealthy and middle-income countries, the situation in developing countries will need to be very closely watched. The same virus that causes manageable disruption in affluent countries could have a devastating impact in many parts of the developing world.

Co-infection with HIV

The 2009 influenza pandemic is the first to occur since the emergence of HIV/AIDS. Early data from two countries suggest that people co-infected with H1N1 and HIV are not at increased risk of severe or fatal illness, provided these patients are receiving antiretroviral therapy. In most of these patients, illness caused by H1N1 has been mild, with full recovery.

If these preliminary findings are confirmed, this will be reassuring news for countries where infection with HIV is prevalent and treatment coverage with antiretroviral drugs is good.

On current estimates, around 33 million people are living with HIV/AIDS worldwide. Of these, WHO estimates that around 4 million were receiving antiretroviral therapy at the end of 2008.

CRUCIAL KNOWLEDGE FOR WOMEN


Share/Save/Bookmark

UNDERSTAND THE SITUATION

24 JULY 2009 | GENEVA -- The number of human cases of pandemic (H1N1) 2009 is still increasing substantially in many countries, even in countries that have already been affected for some time.

Our understanding of the disease continues to evolve as new countries become affected, as community-level spread extends in already affected countries, and as information is shared globally. Many countries with widespread community transmission have moved to testing only samples of ill persons and have shifted surveillance efforts to monitoring and reporting of trends. This shift has been recommended by WHO, because as the pandemic progresses, monitoring trends in disease activity can be done better by following trends in illness cases rather than trying to test all ill persons, which can severely stress national resources. It remains a top priority to determine which groups of people are at highest risk of serious disease so steps to best to protect them can be taken.

In addition to surveillance information, WHO is relying on the results of special research and clinical studies and other data provided by countries directly through frequent expert teleconferences on clinical, virological and epidemiological aspects of the pandemic, to gain a global overview of the evolving situation.

Average age of cases increasing

In most countries the majority of pandemic (H1N1) 2009 cases are still occurring in younger people, with the median age reported to be 12 to 17 years (based on data from Canada, Chile, Japan, UK and the United States of America). Some reports suggest that persons requiring hospitalization and patients with fatal illness may be slightly older.

As the disease expands broadly into communities, the average age of the cases is appearing to increase slightly. This may reflect the situation in many countries where the earliest cases often occurred as school outbreaks but later cases were occurring in the community. Some of the pandemic disease patterns differ from seasonal influenza, where fatal disease occurs most often in the elderly (>65 years old). However, the full picture of the pandemic's epidemiology is not yet fully clear because in many countries, seasonal influenza viruses and pandemic (H1N1) 2009 viruses are both circulating and the pandemic remains relatively early in its development.

Although the risk factors for serious pandemic disease are not know definitively, risk factors such as existing cardiovascular disease, respiratory disease, diabetes and cancer currently are considered risk factors for serious pandemic (H1N1) 2009 disease. Asthma and other forms of respiratory disease have been consistently reported as underlying conditions associated with an augmented risk of severe pandemic disease in several countries.

A recent report suggests obesity may be another risk factor for severe disease. Similarly, there is accumulating evidence suggesting pregnant women are at higher risk for more severe disease. A few preliminary reports also suggest increased risk of severe disease may be elevated in some minority populations, but the potential contributions of cultural, economic and social risk factors are not clear.

Vaccine situation

The development of new candidate vaccine viruses by the WHO network is continuing to improve yields (currently 25% to 50 % of the normal yields for seasonal influenza for some manufacturers). WHO will be able to revise its estimate of pandemic vaccine supply once it has the new yield information. Other important information will also be provided by results of ongoing and soon-to be-initiated vaccine clinical trials. These trials will give a better idea of the number of doses required for a person to be immunized, as well as of the quantity on active principle (antigen) needed in each vaccine dose.

Manufacturers are expected to have vaccines for use around September. A number of companies are working on the pandemic vaccine production and have different time-lines.

SITUATION SUMMARY

Novel influenza A (H1N1) is a new flu virus of swine origin that was first detected in April, 2009. The virus is infecting people and is spreading from person-to-person, sparking a growing outbreak of illness in the United States. An increasing number of cases are being reported internationally as well.

It’s thought that novel influenza A (H1N1) flu spreads in the same way that regular seasonal influenza viruses spread; mainly through the coughs and sneezes of people who are sick with the virus.

It’s uncertain at this time how severe this novel H1N1 outbreak will be in terms of illness and death compared with other influenza viruses. Because this is a new virus, most people will not have immunity to it, and illness may be more severe and widespread as a result. In addition, currently there is no vaccine to protect against this novel H1N1 virus. CDC anticipates that there will be more cases, more hospitalizations and more deaths associated with this new virus in the coming days and weeks.

Novel influenza A (H1N1) activity is now being detected through CDC’s routine influenza surveillance systemsand reported weekly in FluView. CDC tracks U.S. influenza activity through multiple systems across five categories. The fact that novel H1N1 activity can now be monitored through seasonal surveillance systems is an indication that there are higher levels of influenza-like illness in the United States than is normal for this time of year. Most of the influenza viruses being detected now are novel H1N1 viruses.

CDC continues to take aggressive action to respond to the outbreak. CDC’s response goals are to reduce the spread and severity of illness, and to provide information to help health care providers, public health officials and the public address the challenges posed by this new public health threat.

CDC is issuing updated interim guidance daily in response to the rapidly evolving situation.

CDC has issued interim guidance for clinicians on identifying and caring for patients with novel H1N1, in addition to providing interim guidance on the use of antiviral drugs. Influenza antiviral drugs are prescription medicines (pills, liquid or an inhaler) with activity against influenza viruses, including novel influenza H1N1 viruses. The priority use for influenza antiviral drugs during this outbreak is to treat severe influenza illness, including people who are hospitalized or sick people who are considered at high risk of serious influenza-related complications.

CDC has developed a PCR diagnostic test kit to detect this novel H1N1 virus and has now distributed test kits to all states in the U.S. and the District of Columbia and Puerto Rico. The test kits are being shipped internationally as well. This will allow states and other countries to test for this new virus. This increase in testing will likely result in an increase in the number of confirmed cases of illness reported. This, combined with ongoing monitoring through Flu View should provide a fuller picture of the burden of disease in the United States over time.

Scientists dig for lessons from past pandemics

If there's a blessing in the current swine flu epidemic, it's how benign the illness seems to be outside the central disease cluster in Mexico. But history offers a dark warning to anyone ready to write off the 2009 H1N1 virus.

The Spanish flu epidemic of 1918 sickened an estimated third of the world's population.

In each of the four major pandemics since 1889, a spring wave of relatively mild illness was followed by a second wave, a few months later, of a much more virulent disease. This was true in 1889, 1957, 1968 and in the catastrophic flu outbreak of 1918, which sickened an estimated third of the world's population and killed, conservatively, 50 million people.

Lone Simonsen, an epidemiologist at George Washington University, who has studied the course of prior pandemics in both the United States and her native Denmark, says, "The good news from past pandemics, in several experiences, is that the majority of deaths have happened not in the first wave, but later." Based on this, Simonsen suggests there may be time to develop an effective vaccine before a second, more virulent strain, begins to circulate.

As swine flu -- also known as the 2009 version of the H1N1 flu strain -- spreads, Simonsen and other health experts are diving into the history books for clues about how the outbreak might unfold -- and, more importantly, how it might be contained. In fact, the official Pandemic Influenza Operation Plan, or O-Plan, of the U.S. Centers for Disease Control and Prevention, is based in large part on a history lesson -- research organized by pediatrician and medical historian Dr. Howard Markel of the University of Michigan.
Markel was tapped by the CDC to study what worked and what didn't during the 1918 flu disaster. Markel and colleagues examined 43 cities and found that so-called nonpharmaceutical interventions -- steps such as isolating patients and school closings -- were remarkably successful in tamping down the outbreak. "They don't make the population immune, but they buy you time, either by preventing influenza from getting into the community or slowing down the spread," Markel said.

Markel describes a dramatic example in the mining town of Gunnison, Colorado. In 1918, town leaders built a veritable barricade, closing down the railroad station and blocking all roads into town. Four thousand townspeople lived on stockpiled supplies and food from hunting or fishing. For 3½ months, while influenza raged in nearly every city in America, Gunnison saw not a single case of flu -- not until the spring, when roads were reopened and a handful of residents fell sick.

Nonpharmaceutical interventions, or NPIs, also proved effective in big cities such as New York, according to Markel. In fact, the sooner cities moved to limit public gatherings or isolate patients, the less severe their experience tended to be -- as much as an eight- or ninefold difference in case and death rates, he says. Based on this guidance, the CDC preparedness plan devotes dozens of pages to potential NPIs, from voluntary isolation to reorganizing company work schedules to reduce the density of people sitting next to each other in the office or while riding trains and buses.

If it seems odd to base medical strategy on 90-year-old newspapers, the approach is increasingly popular. "There's a big case for looking at history," says Simonsen. "We call it archaeo-epidemiology. You go to libraries and places like that, dig around, collaborate with people like John Barry and try to quantify what really worked."

Barry is the author of "The Great Influenza," perhaps the signature history of the devastating 1918 pandemic. He says the historical record shows that isolating patients worked to slow the spread of flu in 1918, but that attempted quarantines -- preventing movement in and out of cities -- was "worthless."

While Barry supports the CDC's general containment strategy, in the past he has publicly criticized Markel's work. After Markel's findings were published in the Journal of the American Medical Association, Barry wrote a letter in response, saying it wasn't swift action but rather an earlier wave of mild flu, acting like a vaccination, that was probably responsible for New York's relatively low caseload. In the letter, he noted, "New York City Health Commissioner Royal Copeland did tell reporters ... that he would isolate and quarantine cases," but based on his own articles in the New York Medical Journal, he "apparently never imposed those measures." In response, Markel and CDC officials pointed to a decision by the New York Board of Health making influenza a reportable disease, and a 1918 JAMA article describing strict quarantine efforts in New York. Barry says both those sources rely on Copeland's assertions, which he considers unreliable.

It looks superficially like an academic feud, but in this field, different conclusions can suggest radically different approaches to quashing a pandemic. Nowhere is this more true than in research that builds computer models to predict the spread of outbreaks, based on previous ones. Markel, along with most analysts, says that in prior pandemics, the so-called R-naught number -- the number of new infections caused by each infected person -- has been approximately 2.0. The current U.S. pandemic control strategy is based on computer simulations that assume a flu virus with an R-naught between 1.6 and 2.4.

Last year, however, Simonsen and Viggo Andreasen concluded that the true R-naught of the 1918 flu virus was probably somewhere between 3 and 4. Since an epidemic grows exponentially -- each person sickens three others, each of whom infects three more, and so on -- this is a tremendous difference. "It says it's going to be harder than we thought" to control a pandemic, Simonsen says.

Barry agrees. "I do think that some of these things, like isolating [sick people], will take off some of the edge. We hope they'll do more than that. But to think they'll stop a pandemic, that is just not going to happen."

Simonsen says control measures such as the steps taken by Mexico in recent days -- closing schools and restaurants, for example -- are still worth the effort. "It doesn't mean we should give up, because we don't know the R-naught [for swine flu]. We don't know how easily this spreads." But she adds, NPIs are at best a way to buy time. "We just badly need a vaccine. That's the most important thing."

To date, the CDC has emphasized personal protective steps such as washing hands and using hand gels, as opposed to tightening border controls or issuing formal directives to close schools or limit public gatherings. Such steps have been left to state and local officials, who have responded in a variety of ways.

One reason for the delay in stronger guidelines is that swine flu caught planners off guard; they had anticipated being able to recognize a pandemic overseas, weeks or at least days before it hit the United States. At the same time, CDC acting director Dr. Richard Besser said Thursday that it's important to let officials tailor their response to local conditions. "They can take the recommendations we're providing and apply them locally. [By doing that] we hope to learn and see what are the most effective control strategies."
Markel agrees that the best response depends on the particular situation. "History is not predictive science. And the powers of public health officials [in 1918] were much greater. Another difference is that people's trust of doctors and government in 1918 was probably remarkably different.... But what I have found, studying epidemics, is that good planning and good relationships between local state and federal authorities, goes a long way."

THE DEFINITION OF A VIRUS

A virus (from the Latin virus meaning toxin or poison) is a sub-microscopic infectious agent that is unable to grow or reproduce outside a host cell. Viruses infect all cellular life. The first known virus, tobacco mosaic virus, was discovered by Martinus Beijerinck in 1898,[1] and now more than 5,000 types of virus have been described.[2] The study of viruses is known as virology, and is a branch of microbiology.

Viruses consist of two or three parts: all viruses have genes made from either DNA or RNA, long molecules that carry genetic information; all have a protein coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell. Viruses vary in shape from simple helical and icosahedral shapes, to more complex structures. They are about 100 times smaller than bacteria.[3] The origins of viruses are unclear: some may have evolved from plasmids—pieces of DNA that can move between cells—others may have evolved from bacteria.

Viruses spread in many ways; plant viruses are often transmitted from plant to plant by insects that feed on sap, such as aphids, while animal viruses can be carried by blood-sucking insects. These disease-bearing organisms are known as vectors. Influenza viruses are spread by coughing and sneezing, and others such as norovirus, are transmitted by the faecal-oral route, when they contaminate hands, food or water. Rotaviruses are often spread by direct contact with infected children. HIV is one of several viruses that are transmitted through sex.

Not all viruses cause disease, as many viruses reproduce without causing any obvious harm to the infected organism. Some viruses such as hepatitis B can cause life-long or chronic infections, and the viruses continue to replicate in the body despite the hosts' defence mechanisms. However, viral infections in animals usually cause an immune response, which can completely eliminate a virus. These immune responses can also be produced by vaccines that give lifelong immunity to a viral infection. Microorganisms such as bacteria also have defences against viral infection, such as restriction modification systems. Antibiotics have no effect on viruses, but antiviral drugs have been developed to treat life-threatening and more minor infections.

HOW TO CHECK YOUR TEMPERATURE

You can use a thermometer to quickly and easily check temperature. As a precaution, make sure the thermometer is clean and that you follow its operating instructions beforehand.

To begin, take an initial reading of temperature from the person and then approximately 30 min later take another reading to confirm and/or compare the two.

Take readings from either the mouth or the armpit area.

A normal temperature can range from 36-36.8C (97.7-99.1ºF).

A temperature of 38C (100.4F), or above, is classed as a fever.


You can buy thermometers from your local pharmacy. Below are a few different types available.
  • Mercury thermometers- now being phased out. Mercury is poisonous if swallowed, or if it comes into contact with the skin. Do not use on children.
  • Digital thermometers -the reading will be about 0.5C lower than the body's core temp (add 0.5C to the reading to get a more accurate idea of the temperature). Place the thermometer under the tongue for approximately 2-3 minutes. If the person has just eaten something very cold, or hot, wait 10 minutes before taking a reading.
  • Thermometer strips -placed on the forehead. Thermometer strips measure the temp of the skin (rather than your body core) and they are not entirely accurate.
  • Ear thermometers - quick and easy to use, but expensive. Place this thermometer inside the ear gently to avoid injury, follow the directions provided from manufacturer.

If a thermometer is not available, the following signs and symptoms can be a good indication of a high temperature or fever.
  • Skin feels hot to touch - place a hand on the forehead or other p[art of the body.
  • Flushed skin - skin often becomes flushed (red) when you have a fever or high temp.
  • Shivering - as temp goes up and down shivering and feeling very cold is common.
  • Feeling hot and cold - alternating feelings of heat and cold are a sign of high temp.
For the best results and for safety, we recommend using a digital thermometer.

Take the temperature readings from the mouth (hold under tongue for 2-3 min).

Take measurements often to better monitor the bodies temperature.

OVER THE COUNTER PRODUCTS

The information below is to help ease the of FLU symptoms and to eliminate any guess-work when dealing with over the counter medications.

Headaches, body aches, fever, and flu-like symptoms

Medications that reduce pain (analgesics) and fever (antipyretics) are used to relieve headaches, body aches, and fever. The three classes of analgesics/antipyretics that are available OTC are aspirin, acetaminophen, and nonsteroidal anti-inflammatory drugs (NSAIDs).

Some OTC products contain an analgesic/antipyretic as a single ingredient. Others combine an analgesic/antipyretic with a nasal decongestant, an antihistamine, or a cough suppressant. Products listed in the headaches, body aches, fever, and flu-like symptoms category contain an analgesic/antipyretic either alone or in combination with other ingredient(s) to treat cold/flu/allergy symptoms. Examples of products in the headaches, body aches, fever, and flu-like symptoms category include:

  • Aspirin (plain aspirin, coated aspirin, or aspirin mixed with antacid): Aspirin Regimen Bayer Regular Strength, Extra Strength Bayer Plus Caplets, Bufferin Analgesic Tablets, Regular Strength Ascriptin, Ascriptin Enteric, and Alka-Seltzer Extra Strength.
  • Acetaminophen: Tylenol Regular Strength Caplets and Tablets, Aspirin Free Excedrin Analgesic Caplets and Geltabs, Children's Tylenol Chewable Tablets, Elixir, and Suspension Liquid, and Junior Strength Tylenol Coated Caplets and Chewable Tablets.
  • NSAIDs: Advil Caplets, Aleve Tablets and Caplets, Motrin IB Pain Reliever Caplets and Gelcaps, and Children's Motrin Drops.
  • Aspirin plus a decongestant and/or cough suppressant: Alka-Seltzer Plus Cold and Cough.
  • Acetaminophen plus a decongestant and/or cough suppressant: Tylenol Cold Medication Multi-Symptom Caplets and Tablets, Theraflu Flu and Cold Medicine, Actifed Cold and Sinus Caplets and Tablets, and Children's Tylenol Flu Liquid.
  • NSAID plus a decongestant and/or cough suppressant: Advil Cold and Sinus Caplets and Motrin IB Sinus Caplets and Tablets.

Nasal congestion, sneezing, and runny nose

Nasal congestion, sneezing, and runny nose are common symptoms of a cold caused by a virus. The viruses that cause colds induce inflammation that increases the leakage of fluid from the blood vessels into the lining of the nose and even into the nose. This causes swelling of the lining of the nose, obstructing the flow of air, and a runny nose.

Symptoms of hay fever, or allergic rhinitis, are caused by allergens. Allergens are tiny particles that cause cells in the lining of the nose and the airways of the lungs to release histamine and other chemicals. Histamine and these other chemicals are responsible for the leakage of fluid, runny nose, sneezing, and nasal congestion, as well as the itching of the eyes.

Cold symptoms usually resolve in one to two weeks whether treated or not. Antibiotics have no effect on viruses, which are the cause of colds. However, bacterial infections that can follow viral infections, for example, infections of the ears and sinuses, may be treated with antibiotics. For the temporary relief of cold symptoms, plenty of oral fluids such as broth, chicken soup, and tea with lemon and honey and humidification of room air are safe remedies for people of all ages. Saline (salt and water) sprays and mists can also safely provide soothing moisture to dry, irritated nasal passages. In infants and young children, saline nose drops and clearing the nose with a nasal syringe can temporarily relieve nasal obstruction. Allowing infants and young children to sleep upright in car seats also improves the drainage of nasal secretions.

For short-term relief of nasal congestion in older children and adults, nasal decongestants can be used. Nasal decongestants are chemicals (for example, pseudoephedrine, oxymetazoline, etc.) that narrow the blood vessels in the nose, thereby preventing fluid from leaking and the lining from swelling. As a result, the lining shrinks and the nasal passages open. Nasal decongestants can be used topically within the nose (nasal spray, solution, or mist) or can be taken orally (tablets, caplets, or gelcaps). Topical nasal decongestants act faster than the oral decongestants but have a shorter duration of action. Thus, more frequent dosing will be necessary. Oral nasal decongestants frequently are combined with an antihistamine, a cough suppressant, or an analgesic in treating cold/flu/allergy symptoms.

The first step in preventing and relieving symptoms of allergy is to avoid the allergens. If avoiding allergens is not feasible or does not adequately control the allergic symptoms, antihistamines are commonly used to block the effect of histamines. Some of the antihistamines that are available OTC (diphenhydramine, chlorpheniramine, etc.) are called "first generation" antihistamines. These antihistamines have been in use longer, are less expensive, and are more sedating (more prone to cause drowsiness) than the newer, "second generation" antihistamines (fexofenidine, loratidine, etc.), which have minimal sedative effects. OTC antihistamines frequently are combined with a nasal decongestant and sometimes also with a cough suppressant or an analgesic. Generally, antihistamine preparations are not effective for cold symptoms.

Examples of products in the nasal congestion, sneezing, and runny nose category include:

  • Saline solutions as nose sprays or mists: Nasal Moist Solution, Pediamist, Afrin Moisturizing Saline Mist, and Afrin Menthol Moisturizing Saline Mist. Note: Afrin nasal sprays can lead to a rebound worsening of nasal congestion and become habit-forming, especially if overused.
  • Topical nasal decongestants as nasal sprays, mists and drops: Afrin Regular Nasal Spray, Afrin Nose Drops, Duration 12 hour Nasal Spray, Neo-Synephrine Nasal Sprays, and Vicks Vapor Inhaler.
  • Oral nasal decongestant: Drixoral Nasal Decongestant.
  • Oral antihistamine: Benadryl Allergy Chewables and Chlor-Trimeton Allergy Tablets.
  • Oral nasal decongestant combined with an oral antihistamine (may also contain an analgesic): Actifed tablet, Chlor-Trimeton Allergy/Decongestant Tablets, Coricidin "D" Decongestant Tablets, Contac Continuous Action Nasal Decongestant/Antihistamine12 Hour Capsules, Dimetapp Tablets and Liqui-Gels, Sinutab Sinus Allergy Medication Maximum Strength Formula Tablets and Caplets, Sudafed Cold and Allergy Tablets, Tylenol Flu Nighttime Medication Gelcaps, Allegra Tablets and oral suspension, Claritin tablets and RediTabs, Claritin-D, and Vick's NyQuil Hot Therapy.

Cough

A cough is a common symptom of viral respiratory infections and allergies. A cough can also be caused by other conditions, some of them serious. For example, a cough can be a symptom of asthma, acid reflux into the esophagus (gastroesophageal reflux disease or GERD), sinusitis, postnasal drip, bronchitis, cigarette smoking, pneumonia, tuberculosis, hypersensitivity pneumonia (inflammation of the lung from exposure to certain environmental chemicals), and even lung cancer. Therefore, a persistent cough or a cough that is associated with chest pain, fever, weight loss, or blood-tinged or discolored sputum should be evaluated by a doctor.

There are three types of cough medications available OTC for the temporary relief of cough due to a cold. They are oral cough suppressants, oral expectorants, and topical (externally applied) medicines.

Oral cough suppressants

Codeine and hydrocodone are narcotic oral cough suppressants that require a doctor's prescription. Dextromethorphan is an oral cough suppressant that is available OTC. Dextromethorphan is chemically related to codeine and acts on the brain to suppress cough, but does not have the pain-relieving and addictive properties of codeine. Diphenhydramine is another non-narcotic medication that acts on the brain to suppress cough. It is also an antihistamine.

Dextromethorphan and diphenhydramine can be used to relieve a dry, hacking cough. They are not generally used to suppress a productive cough (when sputum is coughed up). Suppressing a productive cough impairs the clearing of secretions and mucous from the airways, which is generally undesirable. However, cough suppressants are sometimes used to suppress even productive coughs if they are especially bothersome and prevent restful sleep.

Oral expectorants

Guaifenesin is an oral expectorant that is believed to increase the leaking of fluid out of the lung tissue and into the airways. This action thins (liquefies) the thick mucous in the airways and facilitates the clearing of the mucous by coughing. Clearing of mucous from the airways decreases cough.

Topical medications

Camphor and menthol are topical cough medications. Camphor and menthol ointments are rubbed on the throat and the chest as a thick layer. The anesthetic action of their vapors is believed to relieve cough. They are also available as products for steam inhalation. Menthol is also available as lozenges and compressed tablets.

Examples of products in the cough category include:

Cough suppressants: Benylin Adult Cough Formula, Buckley's Mixture, Diabe-Tuss DM, and St Joseph Cough Suppressant for Children and Delsym (effective for 12 hours).

Expectorant: Hytuss, Robitussin and Mucinex.

Topical cough medicines: Hall's Menthol-Lyptus Cough Supp. Drops, Mentholatum, Vick's VapoRub, and Vick's Vaposteam.

Cough suppressant plus an expectorant and other cold/flu/allergy ingredients: Alka-Seltzer Plus Cold and Cough, Alka-Seltzer Plus Cold and Flu, Comtrex Deep Chest Cold & Congestion Relief, Coricidin HBP Cough and Cold Tablets, Dimetapp Cold and Cough Liqui-Gels Maximum Strength, PediaCare Cough-Cold Liquid and Chewable Tablets, Robitussin Maximum Strength Cough and Cold, TheraFlu Flu Cold and Cough Medicine, and Triaminic AM Cough and Decongestant formula.

Since many of these combinations also contain an antihistamine, a decongestant, and an analgesic in addition to the cough suppressant and expectorant, they also provide relief of nasal congestion, sneezing, fever, and aches.

In October 2000, an advisory panel of the U.S. Food and Drug Administration (FDA) recommended that phenylpropanolamine (PPA), an ingredient contained in many OTC and prescription cold medications as well as weight loss products, be classified as unsafe because of reports of stroke associated with the this ingredient. Many companies voluntarily chose to reformulate their products to exclude phenylpropanolamine. The FDA is taking steps to remove phenylpropanolamine from all drug products and has requested that all drug companies discontinue marketing products containing this ingredient.

Sore throat and other symptoms

Viruses are the most common cause of sore throat. A sore throat caused by a cold virus usually resolves in one to two weeks without treatment. On the other hand, a sore throat caused by the streptococcus bacterium (strep throat) should be treated with antibiotics to prevent damage to the heart valves. Generally, streptococcus bacteria cause a more severe sore throat and a higher fever than viral sore throats. Sneezing, runny nose, and cough more frequently accompany sore throats due to a cold virus, rather than streptococcus infections. Sometimes, a throat culture is necessary to establish the cause of the sore throat.

Medications that are available OTC for the temporary relief of sore throat due to the common cold usually contain anesthetics such as benzocaine and dyclonine or menthol and come in the form of lozenges, gargles, and sprays. Children often prefer Popsicles, ice cream, yogurt, pudding, smoothies, or other cool/soft foods in lieu of traditional medications. Aside from their analgesic effects, these foods also provide some nutritional benefit.

Examples of sore throat medications: Cepacol Sore Throat Maximum Strength and Sucrets sore throat lozenges.

What about vitamin C and zinc?

Vitamin C is an antioxidant. In the 1970s, Linus Pauling proposed that vitamin C can reduce the incidence and severity of common cold. To date, there is no conclusive evidence that mega doses of vitamin C prevent colds or decrease the severity and duration of cold symptoms. The article on vitamins further discusses the use of vitamins and antioxidants in preventing diseases.

Zinc has been proposed as an antiviral medication. Some studies suggest that the frequent administration of zinc lozenges may reduce the severity and duration of cold symptoms if started within hours of the onset of cold symptoms, while other studies have not supported this conclusion. No studies have conclusively demonstrated the effectiveness of zinc in children either.

Important considerations for the safe use of OTC products

To use OTC products safely, it is important to understand (1) their side effects, (2) their effects on other underlying medical conditions such as diabetes mellitus, high blood pressure, asthma, and other conditions, (3) their interactions with other prescribed medications such as antidepressants, blood thinners, and high blood pressure medicines, and (4) the product's limitations.

The following guidelines are provided to help consumers make more informed choices when selecting OTC products:

  1. Always read the labels and know the ingredients in the products. Never take more than the recommended dose without checking with your doctor first.
  2. Do not use aspirin-containing medicines for children and teenagers with influenza, chickenpox or other viral illnesses. Rare cases of Reye syndrome have been associated with the use of aspirin in this population. Reye syndrome is a serious illness characterized by liver damage, vomiting, and sometimes coma. It has a 50% mortality rate, and those who survive can be left with permanent brain damage. Therefore, acetaminophen-containing products are recommended for children with fever. NSAIDs may be used in children over six months of age.
  3. Aspirin and NSAIDs can cause ulcers and increase the risk of bleeding, and should be avoided by people with known ulcer disease or certain blood diseases. People who are scheduled for elective surgeries should inform their doctors that they are taking aspirin or NSAIDs.
  4. A true aspirin allergy is rare. Aspirin allergy consists of hives, occasionally difficulty breathing, and rarely shock, within three hours of taking aspirin. Aspirin allergy is most common among individuals who have asthma, urticaria, and nasal polyps. Individuals with aspirin allergy should also avoid NSAIDs because they are chemically similar to aspirin.
  5. Aspirin can cause complications during pregnancy and should be avoided during pregnancy.
  6. Aspirin can increase the effectiveness of blood thinning by Coumadin and may increase the risk of bleeding.
  7. Topical (sprays or mists) nasal decongestants act more quickly than oral nasal decongestants. However, the effects of topical nasal decongestants are short-lived. Topical nasal decongestants should be used for only three to five days at a time since more prolonged use can lead to rebound congestion with worsening nasal congestion. Patients with rebound congestion complain of stuffy nose despite frequent applications of the nasal decongestant. Treatment of rebound congestion involves the slow withdrawal of the nasal decongestant (one nostril at a time) and applying saline nose sprays or drops to provide moisture.
  8. Nasal decongestants can aggravate high blood pressure and should not be used in people with uncontrolled high blood pressure without permission from the doctor.
  9. Oral nasal decongestants can interfere with the action of a class of antidepressants called MAO inhibitors.
  10. Oral nasal decongestants can affect diseases such as hyperthyroidism, diabetes mellitus, and coronary artery disease. Oral nasal decongestants and antihistamines can also precipitate urinary obstruction in patients with enlarged prostates (prostate hypertrophy or BPH). Patients with these conditions should consult their doctors before using OTC products.
  11. OTC antihistamines can cause drowsiness. People taking antihistamines should avoid driving or performing activities that require alertness. They should also avoid alcohol and other sedatives.
  12. Some antihistamines can cause excessive drying of secretions, making it difficult to clear secretions. The accumulation of dried secretions in the airways can aggravate breathing difficulties in people with chronic bronchitis and emphysema.
  13. Infants and young children are sensitive to the side effects of antihistamines and nasal decongestants. They can become irritable, restless, or drowsy with these medications. Occasionally, hallucinations and psychosis can occur. Therefore, the parents or caretakers of infants and young children with cold or allergy symptoms should consult their pediatrician before using any of these products. Recent concerns by the FDA suggest that young children should not take many of the commonly used cold and cough medicines.

Avoiding outdoor allergens

  • People who are sensitive to outdoor allergens should follow pollen counts and avoid outdoor activities when pollen counts are high.
  • Keep the house and car windows closed and use air conditioners.
  • People who are allergic to grass should avoid playing in grassy areas during spring and early summer.
  • Individuals who are allergic to outdoor molds should not mow the grass, rake leaves, or disturb compost.

Avoiding indoor allergens

  • Placing pillows, mattresses, and box springs inside airtight plastic covers that are cleaned weekly can reduce house dust mite exposure. Avoid down pillows.
  • Removing dust-collecting furniture such as bookshelves, TV cabinets, stuffed toys, rugs, and other dust-catching fabrics from the bedrooms can also reduce house dust mite exposure.
  • Keeping pets outside or at least keeping them away from the bedroom of an allergic individual can help decrease animal allergen exposure. Washing cats frequently can help decrease cat allergens. It may be necessary to remove the cat from the household.
  • Venting moist areas such as bathrooms, kitchens, and basements can reduce indoor mold exposure.
  • HEPA air filtration devices (freestanding or installed in the air heating or cooling system of the home) can decrease the amount of pollen, mold spores, and animal allergens in the air. HEPA filtration devices installed on vacuum cleaners can reduce the circulation of house dust mite feces while vacuuming.
  • Wear masks while vacuuming or dusting.
