The 8 May Morbidity and Mortality Weekly Report released today reports new details about the swine flu outbreaks in Mexico and the United States, revealing much higher numbers of suspected and confirmed cases than previously reported. Among the highlights: Mexico as of 6 May had nearly 12,000 suspected cases, more than 1000 others confirmed; the United States had more than 600 confirmed and 800 probable, and testing was showing that more than 99% of the probable cases were proving to be positive for the A (H1N1) virus. The two countries show a "similar age distribution" in their cases, and the report notes that "the percentage of patients requiring hospitalization appears to be higher than would be expected during a typical influenza season."
