 CURRENT SUMMARY COMMENTS

12/19/2011 Comments: Over the past 10 weeks the percentage of patients with ILS has been relatively flat with up-and-down flucuations. ILS increased in October through mid November, dropped from mid-November to early December and have increased in the past two weeks. The pattern is generally consistent with confirmed cases of viruses detected by the UW Virology Laboratory.

10/01/2011 Comments: Influenza-like symptoms (ILS) have been relatively flat since the end of the 2010-2011 flu season (end of April). This is consistent with the confirmed cases of viruses detected by the UW Virology Laboratory.  If symptoms found in the field start to increase in the first two weeks of October it will be consistent with prior year's trends, and consistent with the start of a new flu season.
