CDC: Flu season picks up, widespread in 5 states December 31, 2011 at 6:17 PM EST - Updated June 23 at 4:32 AM ATLANTA (AP) - Flu season appears to be picking up. The Centers for Disease Control and Prevention says five states had widespread reports of flu last week, up from zero two weeks earlier. A CDC report released Thursday says four of the states were in the South - Alabama, Mississippi, Georgia and Virginia. The other was New York. The report also says that tests of about 120 virus samples show the circulating flu strains seem to be well-matched to this season's flu vaccine. Health officials say an estimated 23,600 flu-related deaths occur each year. ___ Online: CDC report: http://www.cdc.gov/flu/weekly/ Copyright 2010 The Associated Press. All rights reserved.
