CDC Updates H1N1-Related Estimates
The Centers for Disease Control and Prevention (CDC) today released updated estimates of 2009 H1N1 cases and related hospitalizations and deaths from April 2009 through Jan. 16, 2010.
The CDC estimates that between 41 million and 84 million cases of 2009 H1N1 occurred between April 2009 and January 16, 2010. The mid-level in this range is about 57 million people infected with 2009 H1N1. The agency also estimates that between about 183,000 and 378,000 H1N1-related hospitalizations occurred between April 2009 and Jan. 16, 2009. The mid-level in this range is about 257,000 2009 H1N1-related hospitalizations. Between about 8,330 and 17,160 2009 H1N1-related deaths occurred between April 2009 and Jan. 16, 2010. The mid-level in this range is about 11,690 2009 H1N1-related deaths. Less than 5 percent of increases in the estimates from one reporting date to the next are the result of delayed reporting in cases, hospitalizations and deaths.
