DECATUR, Ga. – The DeKalb County Board of Health has identified Eastern Equine Encephalitis (EEE) virus at one of its mosquito surveillance sites in the southern part of the county. EEE is transmitted to humans through the bite of an infected mosquito. EEE is a bird disease that is occasionally found in horses and rarely in humans.

To reduce the potential for EEE, West Nile Virus (WNV) and other mosquito-borne diseases, the Board of Health conducts a comprehensive mosquito control program. Throughout the county, technicians routinely trap mosquitoes that are tested for viruses. They also work with residents to eliminate mosquito breeding locations. Measures include placing larvicide in areas with standing water, like in storm drains, which keeps young mosquitoes from becoming flying, biting adults.

While most people who are infected with EEE have no symptoms, some individuals get a flu-like illness with fever, headache, and sore throat. In severe cases, EEE can cause brain swelling and affect the central nervous system. There is no specific treatment for EEE; care is based on symptoms.

The most effective way to protect against EEE and WNV infection, and all mosquito-borne diseases, is to prevent mosquito bites. Observe the “Five D’s of Prevention” during outdoor activities:

Horse owners are encouraged to vaccinate their animals against both EEE and WNV and to clean out watering sources, such as buckets and troughs, every three to four days to prevent mosquito breeding.
