Michigan health department confirms human eastern equine encephalitis case
- On Wednesday, the Michigan Department of Health and Human Services confirmed a Roscommon County resident contracted eastern equine encephalitis, marking the state's first human case since 2021.
- The virus spreads to humans through infected mosquito bites; Chief Medical Executive Natasha Bagdasarian noted EEE carries a 30% fatality rate among people who become ill.
- MDHHS is conducting fresh mosquito trapping and laboratory testing in Roscommon County to determine local risk, as the state previously detected no animal EEE activity this year.
- Officials urge residents to use Environmental Protection Agency-registered repellents and wear long sleeves and pants, though repellents should not be applied to children younger than two months old.
- While only a few human cases occur annually in the United States, physicians advise monitoring for fever, headache, chills, and nausea, which may progress to seizures or coma.
