Michigan adds to Legionnaires’ death toll

The Michigan Department of Health and Human Services reported April 11 that there were three additional cases of Legionnaires' disease during a 2014-2015 outbreak, including two deaths. That brings the total to 91 infections and 12 deaths related to the outbreak in Genesee County, where Flint is located.

The new cases were found when hospital testing records were reexamined. Two of the new cases had not been appropriately reported to the MDHSS. The third case was reported to a different jurisdiction and was not connected to the outbreak in Genesee County.

Fifty of the Legionnaires' cases in this particular outbreak are believed to have originated at a local hospital that uses the City of Flint municipal water system. The health department, however, said it was not sure if the lead-contaminated Flint River water is related to the outbreak.


Between May 2015 and October 2015, there were 46 Legionnaires' disease cases and seven deaths confirmed in the Genesee County outbreak, according to the health department. There were an additional 45 Legionnaires' disease cases between June 2014 and March 2015, including five associated deaths. There were no cases reported in April 2015.
