Living with Eastern equine encephalitis
A virus spread by mosquitoes that usually causes no symptoms or a short illness, but can sometimes cause swelling in the brain.
Understanding Eastern equine encephalitis
Most infected people have no symptoms, but some develop fever, headache, and vomiting. Symptoms begin within 4 to 10 days of infection, and most people recover in 1 to 2 weeks. A small number develop swelling of the brain and severe neurological symptoms that can be permanent. Diagnosis is based on symptoms, blood tests, and sometimes an MRI of the brain.
