HEPATITIS E The infection caused by the hepatitis E virus (HEV) which was discovered in 1980, is essentially a water-borne disease. Formerly termed enterically transmitted hepatitis non-A, non-B (HNANB), HEV is a 29-nm to 32-nm RNA virus with 4 genotypes (type 1, 2, 3 and 4). Transmission The hepatitis E virus is transmitted mainly through the faecal-oral route, due to faecal contamination of drinking water. Other transmission routes have been identified, which include : (a) food-borne transmission from ingestion of products derived from infected animals; (b) transfusion of infected blood products (c) veical transmission from a pregnant woman to her foetus.
