TAMPA — A horse euthanized in July was infected with Eastern equine encephalitis acquired in northwest Hillsborough County, officials confirmed Thursday.
The finding led health officials to again warn residents to protect themselves against mosquitoes that could carry the rare illness.
EEE, which causes swelling in the brain, is carried by mosquitoes. It cannot be transferred by humans, only through bites of an infected mosquito.
According to the Florida Department of Health, initial symptoms include fever, headache, fatigue, loss of appetite, vomiting and diarrhea. It can lead to seizures, coma and death.
The last confirmed human case in Hillsborough was in March, when an unidentified victim became ill.
Hillsborough has been under a mosquito-borne advisory since March 25.
