On a side note, I'm very curious about the "death due to immune system reaction" idea. I mean, if this is true, some of the Americans should've been killed by now. And a previous poster suggested that, due to the lower health standards, Mexicans have better immune systems (respectfully, I'm pretty skeptical of this notion). Wouldn't that lower the Mexico City/swine flu death rate against (in this idea) a higher American death rate?
Is it bad form to reply to one's own post? Meh, whatev.

"... Health experts worry about a flu that kills healthy young adults — a hallmark of the worst global flu epidemics. Deaths from most ordinary flu outbreaks occur among the very young and very old. Why the two countries are experiencing the illness differently is puzzling public health experts, who say they frankly just don't know. It may be that the bug only seems more deadly in Mexico ...
Other ideas about the difference include:
_Genetic analysis of virus samples in the two countries is continuing. The CDC says tests results show the U.S. and Mexican viruses are essentially the same, but some experts have not ruled out the possibility that the virus is changing as it leaks across the border to the north.
_Perhaps nutrition levels are worse in some Mexican communities — poor nutrition can degrade a person's immune defenses, and make them more susceptible to illness.
_Air quality in Mexico City is considered terrible. That too may have affect patients confronted with a novel respiratory disease.
_Access to medical care has been an issue in Asia, where a rare bird flu — which does not spread easily from person-to-person — has killed more than 200 over the last several years. Maybe Mexican patients have also had trouble getting medical care or antiviral drugs, some have speculated — even though the government provides health care.
All that is speculation at this point.
"The question of why the virus appears to be more virulent in Mexico is one that we are looking intensively into," the CDC's Schuchat said. "Rather than speculate, it's important for the science to lead us on this."
