Hepatitis E Virus

This caused some public concern in 1997 when it was isolated from pigs' livers which were suffering from another condition. Antibodies were found to be widespread in the pig population of the Mid-western United States. It was shown later that the pig hepatitis virus was distinct from the human one and there was no cross-species transmission. Hepatitis E has also been identified in pigs in Australia. This virus should not worry pig farmers.
