Mosquitoes Still a Risk for EEE Until First Freeze
The first confirmed case of Eastern Equine Encephalitis has been found in Southeast Michigan. Eastern Equine Encephalitis is a viral disease transmitted by mosquitoes. It is usually seen in late summer and early fall and can be transmitted to humans.
Horses can be vaccinated against the disease, and that helps to stop the risk of spread to humans. The horse that was found to have the disease in Livingston County had not been vaccinated and had to be euthanized after showing severe symptoms and rapidly declining health.
There is a 90% fatality rate in horses that contract the disease. Symptoms include fever, lethargy, and depression, and eventual neurological problems.
Last year, Eastern Equine Encephalitis, which has a 33% fatality rate in infected humans, was confirmed in four human cases. Humans can only contract the disease from a mosquito bite, not from contact with horses.
Using the typical mosquito control measures like sprays with DEET, window screens, and avoidance are the best ways to prevent mosquito bites. The first overnight freeze of the fall usually kills off the mosquitoes and ends the risk of Eastern Equine Encephalitis for the year.
