Reports of lab-confirmed Influenza A are increasing in Michigan at this time, most notably in the Southeast and Southwest regions of the state. Flu-associated hospitalizations and reports of influenza-like illness outbreaks in long term care facilities are on the rise as well. The weekly estimated flu activity in Michigan has been upgraded to 'regional' activity to reflect these increases. The majority of subtyped influenza specimens continue to be A/H3N2 virus. Sporadic influenza B viruses are also being seen. National data suggest that the 2016–2017 flu vaccine is a good match to the viruses circulating up to this point in the season.
Local health departments and medical providers are reminded to promptly report any congregate setting outbreaks, potential pediatric influenza deaths, and unusually severe influenza cases to the MDHHS Division of Communicable Disease at 517-335-8165.

Vaccination throughout the influenza season is strongly encouraged. Plenty of flu vaccine is still available. A press release on flu activity will be issued by MDHHS shortly. Definitions of the influenza reporting levels can be found in the Alert Details section of the MIHAN homepage.
