Detection of Rat Hepatitis E Virus in Pigs, Spain, 2023

Emerg Infect Dis. 2024 Apr;30(4):823-826. doi: 10.3201/eid3004.231629.


We identified rat hepatitis E virus (HEV) RNA in farmed pigs from Spain. Our results indicate that pigs might be susceptible to rat HEV and could serve as viral intermediaries between rodents and humans. Europe should evaluate the prevalence of rat HEV in farmed pigs to assess the risk to public health.
