Eastern Equine Encephalitis confirmed in Maryland horse

A horse in Worcester County, Maryland has tested positive for Eastern equine encephalitis (EEE),  a mosquito-bourne virus which can be fatal to horses and cause serious disease in humans. Although the County is spraying for mosquitoes, horse owners in the area are  strongly encouraged to discuss vaccinations with their veterinarians.

The US averages 15 cases of EEE a year, usually within southern and eastern states. Symptoms of EEE in humans include fever, vomiting, photophobia (fear of light), and headache, with siezures, coma and eventual death possible as secondary symptoms. The case fatality in humans can be as high as 60%, with survivors often experiencing severe brain damage.
