Note: Fewer ILINet providers report during the summer.

Since October 4, 2009, 549 specimens tested by our Bureau of Labs (BOL) have been positive for influenza. A total of 368 positive specimens have been reported by other labs. All subtyped influenza A viruses this season have been 2009 H1N1. Five influenza B specimens have been identified this season.
