Michigan's First West Nile Virus Activity of 2018 Detected in Saginaw Co

The mosquito most common for transmitting West Nile virus is the Culex tarsalis.

It's the state's first case this year.

The health department recommends keeping skin covered when outside at dawn and dusk when mosquitoes are most active.

The city of Grand Forks says a pool of mosquitoes collected Wednesday has been identified as having West Nile virus. The public health department urges Grand Forks residents to limit their outdoor activities in the time between dusk and dawn, wear long sleeves and trousers when possible and use repellent spray containing DEET.

West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Hanson estimates that 80 percent of people who contract the virus do not have symptoms severe enough to visit a doctor.

Symptoms of West Nile virus disease include slight fever or headache in mild cases, and high fever, disorientation and even paralysis or death in severe infections. More serious complications include neurological illnesses, such as meningitis and encephalitis.

Forty people were diagnosed with the West Nile virus in MI past year, with one death reported. Consult a physician before using repellents on infants. Use bed nets when sleeping outdoors or in conditions with no window screens.
