West Nile virus has been confirmed in northern Michigan, with cases reported in multiple areas, including Emmet County and Midland County. There have been reports of deaths related to West Nile virus in the state, including a resident of Wayne County. However, it is unclear if all reported cases and deaths are directly related to the West Nile virus confirmation in northern Michigan, as there are also mentions of another mosquito-borne virus, Eastern Equine Encephalitis, in the region.
