The Swine Flu "Pandemic"

Welcome to the new world of medical sensationalism. The recent "outbreak" of the H1N1 virus, aka "swine flu" has provided some of the major news networks with the ultimate story. Scare the public and increase ratings, it worked with terrorism, and now it appears to be working with the swine flu pandemic. From pictures of Dr. Gupta, CNN's medical authority, wearing a worried look and a face mask, to Vice-President Biden's gaff about why all Americans should cease flying immediately, the American people are being fed misinformation on H1N1 at an alarming rate. And they are scared. Airline stocks are plummeting, people are avoiding pork, and sales of surgical masks are increasing exponentially. In Vermont, the National Gaurd is escorting deliveries of anti-viral medicines to hospitals. And, of course, the religious crazies are out predicting the "end of days".

Every day we are reminded of the swine flu death toll. For example, on today's CNN page (May 3, 2009), there is a headline article stating that "Confirmed Cases of H1N1 Virus Approach 900". It is important to realize that 900 deaths, while seemingly significant, really is not. Cancer kills over 440,000 Americans per year, or about 1200 a day. Over 9000 Americans, 24 each day, die from contaminants in the food that we eat. In fact, 900 deaths worldwide represents about 0.00013% of the world's population. This is a nasty little virus, with some interesting genetics (see tomorrow's post!), but it is not yet a global killer. And due to some rather quick work by scientists, we already know more about this virus than most.

So why the panic? Mostly because people do not understand the jargon of the people who study infectious diseases. Yes, there is a pandemic... but it is important to recognize what the word pandemic really means. An epidemic is an outbreak of a disease in a localized population, while a pandemic simply means that the epidemic has moved into neighboring populations. In today's world, most epidemics, and all flu outbreaks, go pandemic quickly. A pandemic is not Armageddon, it is simply a widespread outbreak of a disease.

Some people will say that the news networks are just keeping people informed. But the reality is that this bout of swine flu is going to fade rather quickly as summer progresses, and with this fading will be the attention of the American people. But, unfortunately, the virus will be back, and it could return with a vengeance. But due to the actions of the news networks, we are now in the "boy who cried wolf" syndrome. When this virus, or one of its close relatives returns, most people will ignore the advice to get a vaccine, thinking that this is just another "news story", and not a real threat. After all, they have already survived the "threats" from avian and swine flu, how bad can it get? The answer is, very bad indeed. Viruses are patient little objects, and a few seasons of low activity often preclude a true outbreak in a population. H1N1 may not be bad this year, but if it mutates over the summer, we could have problems next year if we don't prepare now by planning ahead and funding the agencies that work to protect us from infectious outbreaks.

For more, quality, information, stop watching the infomercials known as the nightly news, and check out real sources such as the CDC. Take prudent precautions, the same as you would take during any high-disease season. Wash your hands frequently, especially when you have been in public spaces, and see your doctor if you develop flu-like symptoms. But lets stop the panic and sensationalism, and instead use our brains to think.

I have been preaching your sermon to panicked BIO 1102 students for the past two weeks... at least a few of them intend to be vaccinated next year (progress!). I think that the free provision of flu vaccines to those in certain age or high-risk groups (or those who are in close contact with them) is a good idea; is this something that is done in America?
It would be nice if, instead of inciting panic by delivering even the most innocent advice (for instance, washing one's hands) with a "terror face," the news media would provide some basic education on antigenic shift and why the flu will not be dangerous now, but may be so next year, so people know when additional precautions are appropriate.

good point - the panic needs to end soon. Unfortunately, flu shots are not mandatory, even at a university setting where people are very vulnerable due to their close proximity!
