Abstract
Hepatitis E is an acute hepatitis in humans, first recognized in 1980 and caused by the hepatitis E virus (HEV). Mammalian HEVs are divided into four genotypes (1-4) of which gt1 and gt2 are involved in epidemics and gt3 and gt4 are more involved in sporadic cases. The principal mode of spread is faecal-oral from contaminated water supplies, almost exclusively in developing regions. Accumulating evidence indicates that HEV (gt3 and gt4) transmission may be zoonotic in developed regions with swine and perhaps other animal species serving as reservoirs for the virus. The exact transmission routes are unclear, but HEV RNA has been detected in retail pig products.
