Washtenaw County Flu Activity

May 14, 2014:  

Influenza continues to circulate at low levels in Washtenaw County.  A mix of A and B viruses have been diagnosed in the past few weeks.  We peaked locally during the first week of January. Influenza A/H1N1 was the dominant strain this season. Respiratory illness rates in schools and child care centers are low.  
Local hospitalizations associated with influenza infection continue.  The age range of hospitalizations in Washtenaw residents to date is 1 month to 91 years, with almost half under the age of 50 (this is typical for A/H1N1).  The flu-related deaths have been in older adults with underlying high-risk health conditions.   
Flu curves and hospitalization data from current and previous seasons are available below.
