Eastern Equine Encephalitis is a rare disease caused by a bite from an infected female mosquito.

The virus family is Togaviridae and is closely linked to Western and Venezuelan Equine Encephalitis.

This is one disease you don't want, because between 35% people die once they become sick.

The mosquito responsible for most cases is Culseta melanura although many other species have been identified.

The disease can present its self as anything from a mild flu-like illness to severe headache, fever, seizures, coma and death. 35% of the people who recover from encephalitis have permanent neurological deficits. Symptoms develop 5-15 days after bite. Treatment is limited to supportive care and no vaccine is available (unless you are a horse).

Only 200 cases have been reported since 1964.
