Friday September 2, 2022

Both horse owners and Michigan residents need to take precautions

Branch-Hillsdale-St. Joseph Community Health Agency has been notified by the Michigan Department of Agriculture and Rural Development, and Michigan Department of Health and Human Services, Bureau of Laboratories of a confirmed case of Eastern Equine Encephalitis (EEE) in St. Joseph County. This discovery underscores the need for both horse owners and Michigan residents to take precautions.
