The Mexicans are saying the flu was actually brought in from the US (which is possible, because the human component is mostly from the US northern Midwest and, for some reason, Italy, while the avian/porcine part is mostly from Asia and Lebanon).
It seems to be having a higher death rate in Mexico than it does here, although it’s not striking slum dwellers in Mexico, but healthy, prosperous people such as the head of the Anthropology Museum.
I think Mexico probably noticed that something odd was happening in the resort areas (the main locus of the flu), but because it makes so much money off of these areas, delayed reporting it, giving the disease a chance to really take off. However, it’s not clear that this flu initiated in Mexico. To me, the main question is where it came from - followed by the question of why Americans are not dying from it, but Mexicans are.
SPRING BREAK IN MEXICO Know Before You Go!
Over 100,000 American teenagers and young adults travel to resort areas throughout Mexico over Spring Break each year.
per the US Dept of State
Deaths are bound to begin in the US as the spread continues.
followed by the question of why Americans are not dying from it, but Mexicans are.
Are they the campesinos, the Mongolians who came across the Bering Strait, down the West Coast and settled high in the mexican mountains, who have never interbred with the Spaniards/other Europeans since the 1500s?
Or is it the Mestisos, the part campesino, part european?
Certainly it is not the pure Europas doing the dying.
I suspect that the slum dwellers live in a filthy environment, so their immune system is already "rough and ready" from the abundance of pathogens. The "healthy" people are cleaner, and their immune systems are probably more passive as a result. JMO.
Mexico knows something is going on, and the last reported death rate was near 10% which is something to worry about, particularly if an initial infection fails to provide you immunity from a second infection with the same bug (a bizarre characteristic of swine flu anyway).
“why Americans are not dying from it, but Mexicans are.”
Because their society is filled with filth and crappy medical care.
