In 1 of 2 outbreaks of eastern equine encephalomyelitis virus (EEEV) infection in swine, 280 of 350 pigs died. Histopathologic findings in the brain were typical of EEEV infection. In addition, multifocal necrosis and inflammation were seen in the myocardium. Follow-up investigation in 1 of the herds revealed antibody response to EEEV in surviving pigs and in adult swine. Growth retardation was noticed in surviving pigs. Histologic examination revealed mild lesions in the brain of the survivors.
