Four major mosquito-borne encephalitis viruses which cause human illness are known to be endemic in the United States: Eastern equine encephalitis (EEE), Western equine encephalitis (WEE), St. Louis encephalitis (SLE), and LaCrosse encephalitis (LAC). All of these viruses are maintained in natural cycles involving mosquito vectors and vertebrate reservoir hosts. The reservoir hosts of EEE, WEE, and SLE are numerous species of wild avians, while woodland mammals, primarily members of the squirrel family, serve as hosts for LAC virus. Considering the nature of this conference, the remainder of this paper will be devoted to the former three viruses.
