The probable human case is the seventh mosquito-borne disease detected in Michigan this year. Six of the cases were West Nile virus and one was Eastern Equine Encephalitis.

"This is an important reminder that West Nile Virus and other similar diseases are present in the Fall," Oakland County Health Division Kate Guzmán said. "We strongly encourage residents to protect themselves from mosquitoes until the first hard frost of the year."

The mosquito-borne illness typically reaches its seasonal peak in late August and early September.

What To Know About West Nile Virus

The West Nile virus is spread to humans through the bite of an infected mosquito. Some people who get the virus may develop an illness and may experience mild symptoms such as fever, headache and body aches; occasionally, a skin rash and swollen lymph glands may be noticed. These symptoms may last a few days or as long as several weeks.

People who are older than 50 or have immunocompromised conditions can become seriously ill. There are no vaccines or specific treatments for the infection, according to federal health officials.
