“why Americans are not dying from it, but Mexicans are.”
Because their society is filled with filth and crappy medical care.
No, not really. The people who got the flu weren’t peasants, they weren’t old or ill, and they had good, prompt medical care. Apparently this strain reinfects people. I heard a report on a Spanish radio station (from Spain) of a journalist who had gotten it. He was hospitalized briefly, recovered, went home and was fine for a day or so. Then suddenly he got sick again, went back to the hospital, and was dead of uncontrollable pneumonia within hours.
The Mexican version seems to be much more virulent that what Americans have had; either that, or there is some other condition or even predisposition that makes Mexicans more severely affected by it.
“Because their society is filled with filth and crappy medical care.”
Not to mention living 25 million together in one of the most polluted cities on the planet.
