Pandemic H1N1/09 virus
From Wikipedia, the free encyclopedia
From April 2009 to November 2009, 3,900 people died of the H1N1 pandemic virus in the US. This is sometimes compared to the 36,000 people per year who die from the "common flu", mostly in winter, although this number is an estimate.[31] The death rate of H1N1 in the US can be calculated as less than 0.02% from November 2009 figures from the CDC,[32] and has been explicitly calculated as 0.026% in England.[33]
