Incidence of Hepatitis E Virus Infection in Recipients of Blood or Blood Products Transfusion.

Background Hepatitis E, generally known to be transmitted faeco-orally, has been shown to have significant transmission by blood borne route. Paucity of data on asymptomatic viremia in blood donors and higher incidence of Hepatitis E in haemodialysis patients and thalassemics mandate a prospective study of blood recipients to elucidate the exact incidence and natural history of post transfusion Hepatitis E.
