Eastern equine encephalitis, often referred to as EEE or Triple E, is a rare, but serious disease, largely found in North America and spread through the bite of an infected mosquito, the Centers for Disease Control and Prevention reports.

Eastern equine encephalitis virus is a rare disease that is transmitted by various species of mosquitoes. Experts say that while cases are few and far between, and most people who contract the diseases are asymptomatic, the most severe cases can prove fatal.
