Encephalomyocarditis is caused by a single stranded RNA (ssRNA) virus called '''''encephalomyocarditis virus''''' (EMCV). It is a cardiovirus from the family [[Picornaviridae| Picornaviridae]], and like other picornaviruses it stable over a wide range of pH. The virus is ether-resistant and can be inactivated at 60°C for 30 minutes, but some strains have shown a marked thermal stability.

EMCV causes high mortality in young pigs and reproductive failures in breeding females. Piglets suffer from myocarditis and encephalitis and sudden deaths due to myocardial failure are common. The disease affects the nervous, reproductive, respiratory and circulatory system of pigs. Antibodies for EMCV have been demonstrated in human populations (Tesh, 1978) Tesh RB, 1978. The prevalence of encephalomyocarditis virus neutralizing antibodies among various human populations. American Journal of Tropical Medicine & Hygiene, 27:144-149. but there are no reports that the virus causes human heart disease.
