Both WNV and EEE cause severe, and sometimes fatal, infections in horses.
The best way to avoid exposure to West Nile virus is to avoid mosquito bites. But some cases can worsen to include swelling of the brain. Mosquitoes need only a teaspoon of water to breed.
Most people are infected in OH by the northern house mosquito, Culex pipiens. Symptoms in severe cases of EEE include a sudden onset of headache, high fever, chills, and vomiting.
WNV and EEE are transmitted by mosquitoes, generally in summer and fall, with a peak period for disease transmissions from mid-August to mid-October. The majority of Culex mosquitoes breed in standing water and others are found in freshwater and saltwater marshes, lakes and ponds.
Drain or dump standing water weekly.

- When possible, wear long trousers and long-sleeved shirts while outside.

Make sure that your doors and windows have tight-fitting screens to keep out mosquitoes.
