CDC Situation Update

Flu Activity: According to the final FluView for the 2009-2010 influenza season (May 16–22, 2010), flu activity in the United States declined again from the previous week and is about the same as what is normally seen during the summer in the United States. Only a small number of influenza viruses are being reported, most of which are 2009 H1N1. Flu is unpredictable, but sporadic cases of flu, caused by either 2009 H1N1 or seasonal flu viruses, will likely continue to occur throughout the summer in the United States. Internationally, 2009 H1N1 viruses are still circulating, including in the Southern Hemisphere, which is entering its flu season. For more information, please see the international situation update.
