CDC Estimates 14 Million to 34 Million Cases of Swine Flu (H1N1) So Far

There have been between 14 million and 34 million cases of 2009 H1N1 between April and Oct. 17, 2009, the Centers for Disease Control and Prevention announced yesterday.

It estimates that 2009 H1N1-related deaths range from 2,500 to 6,000.

The report also said that between about 63,000 and 153,000 2009 H1N1-related hospitalizations occurred during that time period.

The CDC warned that the estimated ranges generated by this methodology provide a sense of scale in terms of the burden of disease caused by 2009 H1N1. It may never be possible to validate the accuracy of these figures. The true number of cases, hospitalizations and deaths may lie within the ranges provided or it’s also possible that they may lie outside the ranges.

This methodology is not predictive and cannot be used to forecast the number of cases, hospitalizations and deaths that will occur going forward over the course of the pandemic because they are based on actual surveillance data.
