Thanks. I wasn’t aware of that figure.

Do you know what the H1N1 infection rate was?

From April 12, 2009 to April 10, 2010, CDC estimated there
were 60.8 million cases (range: 43.3-89.3 million), 274,304
hospitalizations (range: 195,086-402,719), and 12,469 deaths
(range: 8868-18,306) in the United States due to the
