The United States: 642 Confirmed Cases in 41 States (2 deaths). CDC notes an additional 845 probable cases have been reported from 42 states nationwide. This is a total of 1,487 confirmed and probable cases in 44 states in the United States.

Note from CDC:
CDC-developed PCR diagnostic test kits to detect this virus have been distributed to all states in the U.S. and Puerto Rico. This increase in testing capacity in the United States likely will result in a rapid jump in the number of confirmed cases in this country once states start doing their own testing. This will be an artifact of testing, but will actually present a more accurate picture of the true scope of novel H1N1 disease in the United States.
