General Overview
According to Stalkup and Chilukuri[1], enterovirus, a small (30 nm), nonenveloped, single-stranded RNA viruses, belongs to the family Picornaviridae. While most of the enterovirus infections are relatively mild and result in complete recovery of the patient, they can also cause severe and fatal diseases such as meningitis, encephalitis, myocarditis, neonatal sepsis, and polio like paralytic diseases. Infection occurs mainly via fecal-oral transmission and less commonly by respiratory droplets. While no known non-human reservoirs have been identified, water-borne, foodborne, and blood-borne transmissions have been reported.
Summary Data
Cliver[2] challenged pigs with Porcine enterovirus type 3 and 7 via oral exposure route.
