The map is based on the weekly Morbidity and Mortality Reports (MMWR) from CDC for cities with 100 K or more population
. According to NIH a typical flu season in the U.S lasts from 40th week of one year (October onwards) to 12th week of the following year (up to March/beginning of April). The latest flu season spanning 2008-2009 is just over. During these six deadly months, the "regular" flu season has claimed lives of nearly 24,000 in 115 cities. Compare that to A/H1N1 aka "swine flu" which for all its media exposure has "so far" proven to be quite tame. Eleswhere on Maker! you may come across maps showing weekly flu deaths during the 2008-2009 flu season.
