West Nile Virus Confirmed In MI, First In 2026

Health officials in Kent County said Tuesday they have identified the West Nile virus, the first Michigan sampling of the virus in 2026.

Officials found the virus in mosquitoes from the 49504 (Grand Rapids) and 49519 (Wyoming) ZIP codes.

"These findings reinforce that mosquitoes are active in our area and capable of spreading illness through their bites," KCHD Environmental Health Division Director Sara Simmonds said. "Simple precautions like applying insect repellent and getting rid of standing water around your home can go a long way in reducing your risk while still enjoying the outdoors."

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 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.

Here are recommendations for avoiding exposure:

• Use insect repellent with 10-35 percent DEET, and always follow label directions
• Wear long sleeves and pants to limit skin exposure
• Avoid outdoor activity during dawn and dusk, when mosquitoes are most active
• Eliminate standing water around your home—refresh bird baths, wading pools, pet bowls, and empty small containers regularly
• Keep screens and gutters in good repair to prevent mosquitoes from entering your home
