Despite the end of flu season in the Northern Hemisphere, the incidence of H1N1 continues to increase. Over 1 million Americans are now estimated to have the virus. Several jurisdictions, including Washington D.C. and Wisconsin, are seeing an unusual number of cases of summer flu linked to H1N1.
In the Southern Hemisphere, the H1N1 virus is displacing the former seasonal strain. Late yesterday the Buenos Aires region joined four other Argentine provinces in declaring a health emergency. Schools have been closed and other social distancing tactics are being implemented. Argentina’s response to the virus has been delayed and complicated by a national political campaign that concluded with an election on Sunday. (More from the Buenos Aires Herald)
