Eight human cases of West Nile virus have been confirmed in Michigan in 2018.
The Michigan Department of Health and Human Services confirmed the cases in one resident of Berrien County, one resident of Kent County, one resident of Oakland County and five residents of Wayne County, including one death. All but one have been hospitalized with neurologic disease.
In addition to the eight human cases, three Michigan blood donors had West Nile virus (WNV) detected in their blood.
According to MDHHS, 2018 WNV activity appears to be statewide. To date, 66 birds have tested positive for WNV from 21 of Michigan’s 83 counties. In addition, 74 WNV positive mosquito pools have been detected in eight Michigan counties.
