* EEE virus
is found in eastern Canada, all states east of the Mississippi River, Arkansas, Minnesota, South Dakota, Texas, the Caribbean, and regions of Central and South America (particularly along the Gulf coast).

Editorial Note: An increased number of EEE cases had been anticipated in 1992 for two reasons: 1) in 1991, EEE virus
had been isolated from Aedes albopictus , a more anthropophilic mosquito vector; and 2) in 1991, an EEE epizootic occurred in the Southeast .
Editorial Note: This is the first documented isolation of EEE virus
This species feeds almost exclusively on birds and is the primary enzootic vector of EEE virus
. These specimens were solicited to determine if WN virus-infected birds were being fed upon as they migrated south in late summer and early fall.
In 1990, EEE virus
was recovered earlier and in greater numbers than at any time previously in these areas.
LANCASTER - The Massachusetts Department of Public Health (MDPH) announced Wednesday that EEE virus
has been detected in a horse from Lancaster.
He said there have been no positive identifications of EEE virus
within the city, adding it is important for the community to understand the clear and distinct differences between the two viruses and the different steps taken for protection against them.
Before the virus inoculation, serum samples from all horses were tested for preexisting antibodies to VEE, eastern (EEE), and western equine encephalitis (WEE) viruses by using an enzyme-linked immunosorbent assay (ELISA) with cell lysates prepared from BHK-21 cells infected with VEEV strain Trinidad donkey (21,22), EEE virus
strain 82V2137 (23), and WEE virus strain Fleming (24).
albopictus in the United States has prompted concern because of its potential for transmission of EEE virus
. This mosquito was imported from Asia to Texas, where it was discovered in 1985, and has since become widespread in the central and southern United States (7).
