The Sanilac County blood donor tested positive for the mosquito-borne virus.
MI health officials have confirmed the first human case of West Nile Virus for 2018.
West Nile virus is spread to humans through the bite of an infected mosquito. Lyon and most surrounding counties remain in a moderate risk while Chase and Morris counties have been elevated from moderate to high risk. City crews also monitor the mosquito population on a weekly basis through the use of mosquito traps to evaluate the effectiveness of larval control, provide early warnings for when adult populations are rising and also test for West Nile Virus. People who are elderly, have compromised immunity, have cancer, have alcoholism or other factors that make them more susceptible to a neuroinvasive disease are more at risk.
There are no vaccines for West Nile and no medical treatments for it, but people who have had the virus before develop immunity to it.
Certain mosquito species carry the West Nile virus, which can cause humans to contract West Nile encephalitis, an infection that can result in an inflammation of the brain.
