Michigan (WJRT) - (8-31-2017) - The Michigan Department of Health and Human Services today confirmed the state’s first human cases of West Nile Virus for 2017.
Four human cases of West Nile have been confirmed: two residents of Montcalm County, and one each from Oakland and Macomb counties.
Their illness onsets range from Aug. 6 to 11 and all have been hospitalized with neurologic disease.
In 2017, West Nile activity appears to be widespread statewide in Michigan. In addition to the four human cases, five Michigan blood donors have had West Nile detected in their blood.
Most people who become infected with West Nile will not develop any symptoms of illness. However, some become sick three to 15 days after exposure.
About one-in-five infected persons will have mild illness with fever, and about one in 150 infected people will become severely ill.
Mild illness may include headache, body aches, joint pain, vomiting diarrhea, or rash.
