The Centers for Disease Control and Prevention says that counting related illnesses caused by the H1N1 virus, the number of deaths from the H1N1 virus has increased by about four times earlier estimates.

Federal health officials now say nearly 4,000 Americans have died from the H1N1 virus since April – the start of the H1N1 flu season. Previous estimates put the number of fatalities at around 1,000, but the death toll has been recalculated to include deaths from flu-related complications, such as pneumonia and bacterial infections.

The CDC estimates that 22 million Americans have gotten the virus and close to 100,000 have been hospitalized.
Eight million children have been infected – 540 have died.
