Swine Flu - Something Smells

First, Mexico said over a hundred were dead.
Then the World Health Organization said 7.
But even as it revised the death figures down, it raised the pandemic rating UP.

Why?

Everyone agrees that there are no difference between the Mexican and US viral strains, but Mexicans are dying and being hospitalized, US patients aren't. If the strains aren't different, then there must be a difference in medical care, patient nutrition or some other aspect of immuno-competency. That is, the Mexicans are deficient in something that none of the US patients are deficient in. But no one is saying there ARE any such differences.

And if there were, what would the difference(s) be?

Everyone is saying that we have to quarantine now because it will otherwise enter the population and emerge much more virulent in a year or two.

That's just stupid.

No one has explained why a virus would get MORE virulent over time. Virii don't get more virulent over time. The idea that it would is completely counter to evolutionary theory.

Killing/incapacitating your host doesn't bode well for you, if you're a virus/bacteria. When the host dies, you die. The more virulent strains die with their hosts. The more incapacitating strains don't spread as efficiently because the host is flat on his back, vomiting into a bucket by himself. It's the weak strains that spread efficiently, not the virulent ones. And if the strains are virtually identical, then when a weaker, more efficiently spread virus gets fought off by a host, the host will be immune to the more virulent strain.

So, if this virus does anything, it will become adapted to the host, and thus LESS virulent over the next few months/years, not more virulent. That's how the Black Death disappeared, that's how a whole host of nasty diseases went away.

Strains always become less virulent over time unless you are attacking them, as with the MRSA bacteria. They get more virulent because we attack the bacteria with antibiotics until only the really virulent ones are left. But antibiotics don't work on virii because antibiotics attack cell membranes - that works great for cells like bacteria, but virii are just DNA strands. Antibiotics can't touch them.

So why is everyone worried about this thing getting more virulent?

The prevalence is microscopic, the flu isn't very virulent, it isn't going to get more virulent, and no one is interested in border control, although everyone seems interested in shutting down schools. Why is it that border control will NOT work and shutting down large public gatherings WILL work?

If wearing scarfs works, then have everyone at school wear scarfs. If it doesn't work, why are people being told it does?

What's the difference between the border around the mouth, around a school, around a church or around a country? Why are some kinds of border control encouraged, others not? And I'm asking this question as someone who has always opposed national border patrols. I don't see the logic in the arguments.

Very little of what I've heard in the news about this virus makes any sense. We've got enormous governmental response to essentially no serious numbers of cases. This whole thing smells to high heaven.
