Through July 2009, a total of 43,677 laboratory-confirmed cases of influenza A pandemic (H1N1) 2009 were reported in the <st1:country-region w:st="on"><st1:place w:st="on">United States</st1:place></st1:country-region>, which is likely a substantial Underestimate of the true number. Correcting for under-ascertainment using a multiplier model, we estimate that 1.8 million?5.7 million cases occurred, including 9,000?21,000 hospitalizations.
