West Nile case in Oakland County underscores mosquito risk this fall

Oakland County health officials confirmed a human West Nile virus case. A county resident, who did not report recent travels, is the first Oakland County case of 2025 and the second in Michigan this year.

The virus is spread by mosquitoes that have bitten an infected bird. Most people do not have symptoms or have a mild illness, but older adults are more likely to develop serious disease. To prevent bites, residents can use EPA registered repellents, remove standing water, wear long sleeves and pants, cover window holes, and limit time outside from dusk until dawn.

The case shows how local health teams handle risk in real time. Privacy rules mean the patient’s name stays private, even as warnings go out. Clear, practical guidance helps people take action without panic.

Mosquito activity changes with the seasons, so messages must be repeated and reinforced. Public health work now links local surveillance to wider county and state efforts, aiming to reduce cases through prevention and control.
