Study: At Its Worst, H1N1 Only Slightly More Serious Than Seasonal Flu - H1N1 - FOXNews.com: "They analyzed data from Milwaukee and New York, two U.S. cities that have kept detailed tabs on outbreaks of H1N1, to calculate a likely mortality rate of 0.048 percent.

'That is, about 1 in 2,000 people who had symptoms of pandemic H1N1 infection died,' Dr. Marc Lipsitch of Harvard University and colleagues wrote.

Probably 1.44 percent of patients with H1N1 who were sick enough to have symptoms were hospitalized, and 0.24 percent required intensive care, they added."
