Eastern equine encephalitis virus is spread to people by the bite of an infected mosquito.

Only a few cases are reported in the United States each year. Most cases occur in eastern or Gulf Coast states.

Although rare, eastern equine encephalitis is very serious. Approximately 30% of people with eastern equine encephalitis die, and many survivors have ongoing neurologic problems. Symptoms of eastern equine encephalitis can include fever, headache, vomiting, diarrhea, seizures, behavioral changes, and drowsiness.

There are no vaccines to prevent or medicines to treat eastern equine encephalitis.
