Last week, I wrote a post about the H1N1 virus (swine flu) and how scientists have discovered that it has some genetic differences from the first time the H1N1 virus spread in 1918. That time it was known as the Spanish Flu, and it wound up killing more people than World War I did (combatants and civilians combined).
The scientists said the genetic difference meant that the current strain of H1N1 was probably no more deadly than a regular yearly flu outbreak, which kills around 36,000 in a normal year. It looks like the scientists were right. The swine flu has turned out to not be the pandemic killer that health officials had feared, and in fact, they seem to be getting a hold on this outbreak.
Now you might think I would be pretty pleased with myself for posting that while others were still beating the pandemic drum. I'm not. That's because I know a little bit about the Spanish Flu (my own grandfather died from it in 1919). Yes, I said 1919.
The outbreak in the Spring of 1918 was not the huge killer. It came back in a second and third wave in the Fall of 1918 and Winter of 1919. It was these second and third waves that turned out to be the nasty killers. The second and third waves were far more virulent than the first.
If you'll forgive me for using a euphemism, we're not out of the woods yet. The normal time for the flu season is Fall and Winter, and it's entirely possible that the H1N1 virus may pay us a second and possibly even a third visit at that time.
Any scientist will tell you that a virus can evolve (or mutate) very fast. What if it has mutated into a much more deadly form when it returns? We could still have a repeat of the pandemic known as Spanish Flu.
I'm not trying to be an alarmist, just a realist. It may not come back. If it does, it may still be fairly benign. But it could also be very nasty and create a real mess. The point is, we must remain vigilant. We can't be caught napping if it returns in a few months.
My sentiments exactly.
ReplyDeleteOn another local blog, I likened the situation to Hurricane Katrina in slow motion (others have made the Katrina analogy; the "slow motion" part is mine, as far as I know.)
After Katrina passed through New Orleans, everyone breathed a collective sigh of relief, because the damage was minimal. Then the 17th Street levee broke. The second and third waves of the H1N1 virus could catch us just as off guard this fall, if the proper precautions aren't taken ahead of time.
To continue with the hurricane analogy, no one knows whether the upcoming flu season be will be Katrina, or merely Rita. There's no need to panic; we just need to hope for the best and prepare for the worst.
