EMCV seropositivity signals endemic exposure in Japanese swine; leaves open current prevalence, clinical impact, and surveillance needs.
Cross-Sectional (n=1,502)
Yes
A serological survey indicates that encephalomyocarditis viral infection was prevalent among pigs in Japan between 1990 and 1991.
Shibata et al. (1993) conducted a cross-sectional in Encephalomyocarditis virus infection (n=1,502). Encephalomyocarditis virus exposure was evaluated on Antibody against encephalomyocarditis virus. Antibodies against encephalomyocarditis virus were found in 25.8% of 1,502 pigs across 84.6% of surveyed farms in Japan, with positive rates tending to increase with age.
