Eastern Equine Encephalitis Virus (EEEV) is a rare but serious virus that primarily affects horses and humans. It is transmitted through the bite of infected mosquitoes, particularly in areas near wetlands. Symptoms in humans can include fever, headache, and in severe cases, neurological issues. The virus is most common in the eastern United States and parts of Central and South America. While there is no specific treatment for EEEV, prevention focuses on reducing mosquito exposure through protective measures and vaccination for horses. The disease can lead to significant health complications, making awareness and prevention crucial.
