  • Description:
    No isolations of Venezuelan equine encephalitis (VEE) virus have been reported from vertebrates in North America in the first 6 months of 1973. However, in January 1973, VEE virus was isolated from 1 pool of 50 Culiseta inornata mosquitoes in Xochimilco, D.F., Mexico (see VEE Annual Survey 1972). In the first 3 months of 1973, Peru reported 3,693 human VEE cases and 2,759 equine cases. Sporadic clinical cases in both man and equines were reported in other countries in South and Central America for the same period. In the United States, surveillance activities are being carried out by a number of cooperating federal, state, and local agencies. Both eastern equine encephalitis (EEE) virus and western equine encephalitis (WEE) virus have been recovered from mosquito pools and equines with encephalitis in the United States. Vaccination of horses against VEE is continuing in the United States, Mexico, and Peru.
