Overview of Swine hepatitis E virus

Swine hepatitis E virus (SHEV) is an enveloped, single-stranded, positive-sense, RNA virus, approximately 7.5 kb in length belonging to the Orthohepevirus genus and Hepeviridae family. SHEV infections generally present as asymptomatic in pigs. However, evidence indicates that animal to human transmission may be possible, making SHEV a notable emerging foodborne pathogen transmitted by consumption of raw or undercooked pork. A recent study found ~6.3% of tested pigs to be viremic for HEV RNA at time of slaughter.
