West Nile Virus Confirmed in Eaton County Birds and Horse
September 27, 2024
In a recent health alert, the Barry-Eaton District Health Department (BEDHD) announced that three birds in Eaton County have tested positive for West Nile virus (WNV). The affected birds include two American Crows and one Red-tailed Hawk. Additionally, earlier in the season, a horse in Eaton County also tested positive for the virus. As of September 20th, 2024, Michigan has recorded 67 animal cases and 19 human cases of WNV. Notably, the Barry-Eaton district has not reported any human cases this year.
West Nile virus, along with Eastern Equine Encephalitis (EEE), are diseases transmitted by mosquitoes. Humans and animals, such as birds and horses, can contract these viruses through mosquito bites. Symptoms often include fever, headache, body aches, vomiting, diarrhea, or rash. While there are no vaccines available for humans, horse owners can vaccinate their animals against both WNV and EEE. Veterinary consultation is recommended for vaccination information.
Reducing mosquito bites is crucial to minimizing the risk of WNV and EEE. Mosquitoes remain active until the first hard frost, so ongoing preventive measures are advised.
Strategies to Prevent Mosquito Bites
- Use insect repellent when outdoors.
- Wear light-colored, long-sleeved shirts and pants.
- Treat clothing and outdoor gear with insect repellent.
- Eliminate standing water around the home, such as in bird baths, wading pools, pet water bowls, or any other containers that can collect water.
Observations of sick or dead birds may signal the presence of WNV or EEE in the area. Residents who encounter such birds are urged to report them to the Michigan Department of Natural Resources (DNR) through their ‘Eyes in the Field’ reporting form, accessible here. These reports help monitor bird mortality, although not every bird will be tested.
