Pigs may be transmission route of rat hepatitis E to humans

New research suggests that pigs may function as a transmission vehicle for a strain of the hepatitis E virus (HEV) common in rats that has recently been found to infect humans. The Rocahepevirus ratti strain is called “rat HEV” because rats are the primary reservoir of the virus. Since the first human case was reported in a person with…
