While the city's Health Department has emphasized that cases of swine flu are declining, the Daily News reports that Centers for Disease Control and Prevention data suggests "half a million New Yorkers have been infected by swine flu." The CDC thinks there are actually 50 times more cases of swine flu than what's been reported to health authorities: "The CDC study was not based on laboratory evidence. Instead, researchers relied on mathematical modelling of surveys conducted in areas, like New York City, that have had high levels of H1N1 infections." Hmm. The Health Department had no comment; so far, the city has had 32 deaths and 804 hospitalizations due to swine flu. The next Health Department update will be on July 1.
