Description
Hepatitis E virus (HEV) is a non-enveloped, positive-sense, single-stranded ribonucleic acid (RNA) virus.[1] HEV is one of the five identified hepatitis viruses (A,B,C,D, E) . Hepatitis E is most similar to hepatitis A, in that they are both transmitted through contaminated food or water. The other types of hepatitis(B,C,D) are transmitted through infected blood, sexual contact and from mother to child. HEV is the causative agent of the infectious disease Hepatitis E. HEVis unique in that it displays different clinical and epidemiologic characteristics depending on where the infection is acquired which is mainly due to the four viral genotypes of HEV that have been identified.[2] Every year there are 20 million hepatitis E infections, with over 3 million symptomatic cases of hepatitis E, and 56 600 hepatitis E-related deaths.[3]
