FluView reports that for the week of February 7 - February 13, 2010, flu activity in the United States was relatively low, with most flu continuing to be caused by 2009 H1N1. Flu activity, caused by either 2009 H1N1 or seasonal flu viruses, may rise and fall, but is expected to continue for weeks. It’s possible that the United States could experience another wave of flu activity, or more likely, localized outbreaks of 2009 H1N1 in communities that have been relatively unaffected by illness thus far, or where 2009 H1N1 vaccination rates may have been lower.
