Public Health, Epidemiology, Medical History: Swine Flu? Over-Hype for Some, A Dress Rehearsal for Others

The alarm around this particular strain [A-H1N1] has a couple of roots. First is, it’s new… it’s novel. And new is always cause for some amount of concern. Second, it does appear to have just recently jumped from one species, pigs, to another, humans. And very commonly, in the whole world of viruses – not just influenzas – when they first make the jump from one species to another is when they’re really hot viruses, dangerous viruses. That certainly was the case with SARS, which had just made the jump from bats to civets, civets to humans.  So we always worry when we see a recent jump. ”

A quote from Laurie Garrett, during an interview with the Online News Hour (transcript link here) on May 1 2009.

.

Ms. Garrett, author of The Coming Plague: Newly Emerging Diseases in a World Out of Balance (1994), and The Betrayal of Trust: The Collapse of Global Public Health (2000), is currently a senior fellow for global health at the Council on Foreign Relations.

How A/H1N1 influenza – identified in Mexico in March 2009 – continues to develop in human populations is still uncertain, as the virus spreads to every continent.  The good news is that clinicians seem to think it is not as virulent as first feared; the bad news is that over time, the possibility still exists that we are witnessing a phenomena that every epidemiologist dreads in his or her lifetime: the emergence of an uncontainable virus in a human population who have little or no immunity against it.

While many people thought the media hype over this emerging virus was of hysterical proportions, and discounted the severity of the strain, a different way to view these events is as a sort of dress rehearsal which demonstrated that world-wide networks of disease surveillance, data-collection and cooperative intelligence sharing are functioning reasonably well.  (But I’m not a virologist so maybe I know no more than the next guy on the street.)

If nothing else, it shows that swarm-intelligence and citizen-journalism is alive and well!

You could say that some of my reactions to public health crises have been shaped in part by having lived in city of San Francisco in the early 1980’s, when a different public health crisis unfolded with the identification of a novel viral infection which came to be known as human immunodeficiency virus.  If you haven’t already read And The Band Played On by Randy Shilts, who was a reporter at the time for the San Francisco Chronicle, it is truly worth the time. *

Let’s hear it for more dress rehearsals, and fewer real-life epidemics.

One response to “Public Health, Epidemiology, Medical History: Swine Flu? Over-Hype for Some, A Dress Rehearsal for Others

    Hi Katleen,
    I stumbled upon your informative post by searching tags on WordPress.
    I’m a caricaturist and journalist in my seasoned fifties and I can tell you: to each economic/politics crisis there’ll be a press hype on a coming catastrophe. A disease, an asteroid, you name it.

    The most important, I think, is for the independent people, like bloggers, to no spam these “viral” hysteria and stop manipulation.
    And, for the sake of public health, to reafirm the importance of reliable, centralized, health institutions (see last paragraph in my post).
    My best
