What is eastern equine encephalitis?

Eastern equine encephalitis (EEE), is a rare disease that causes inflammation of the brain (encephalitis). It is caused by an arbovirus, which means it is spread through the bite of infected mosquitoes. It was first seen in horses (equine) in the 1830s and first diagnosed in a human along the east coast in the 1930s. The virus can only be spread to humans through a mosquito bite. It cannot be spread from human to human or from horse or other animal to a human.
