Epidemiological investigations relating to a case of Eastern Equine Encephalitis in a Trinidadian horse

ABSTRACT

The first equine death in Trinidad known to be due to eastern equine encephalitis (EEE) is reported. Diagnosis was by serologic means only. In related epidemiologic investigations, EEE virus was not isolated from over 5,000 arthropods and the organs of 99 birds, but the serum of five of the birds had neutralizing antibodies to the virus. A strain of Wyeomyia virus and a Turlock-like virus were isolated from the mosquitoes tested (AU)
