Seems common knowledge that arsenic is considered toxic/deadly at high levels, but when you combine it with the drinking water in Mexico, then it does appear that factor could play a role in the high amounts of severe/fatal H1N1 cases there.
The article you found (credible source) also states that:
"The U.S. Environmental Protection Agency considers 10 ppb arsenic in drinking water "safe," yet concentrations of 100 ppb and higher are commonly found in well water in regions where arsenic is geologically abundant, including upper New England (Massachusetts, New Hampshire, Maine), Florida, and large parts of the Upper Midwest, the Southwest, and the Rocky Mountains, Hamilton says."
The piece also supports most of the severe/deadly cases in the U.S.,i.e., Arizona, Texas, Utah, California (all SW or Mexican border states)
But unless CDC and the govt eventually tell the truth about the number of cases, their severity levels, and actual causes of death, we may never have true answers to support the article's theory.
I would hope that they would screen for arsenic levels for likely cases but if they leave your body that quickly, that might be a moot point?
If the CDC/govt lies stop, then time will tell...In the meantime, we could post to this thread severe/fatal cases we are aware of and see if there is some correlation between arsenic water geography and H1N1 here in the states? Just thinking out loud...
