Why Swine Flu Is Deadlier in Mexico

It may not be at all; it's probably a measurement problem

(Newser) – Why is swine flu deadlier on one side of the US-Mexico border than the other? Writing in Slate, David Dobbs examines some explanations as to why the virus has killed about 100 of 1,600 infected in Mexico, and zero of 300 in the United States. The best bet is actually “bad math,” Dobbs writes. “It's perfectly conceivable Mexico has actually had 10,000 or 100,000 cases—or even 1 million cases.”

If the disease is much milder—and more widespread—than thought, that would explain the numbers problem. Otherwise, it’s not spreading very fast. Other possibilities:

  • The virus is partnering with some other bug common in Mexico to make it more deadly—This option, Dobbs says, "remains a distinct possibility."
  • The US and Mexico don’t have the same virus—"Highly remote," Dobbs says: Initial tests "show that the fatal Mexico cases match closely the 40-plus milder cases confirmed in the United States."
  • Mexicans are genetically more susceptible—"The swine flu is new to everyone," Dobbs writes, "(so) we can probably put this 'genetic vulnerability' explanation in a drawer."

Doctors in some hospitals are reporting more deaths than now noted, coverups, sloppy containment, and generally dire situations; others claim things are a bit more orderly. - David Dobbs

Our water is different; Mexico has bacteria that we, in the US, cannot handle.
