Six types of hepatitis infections are accounted for the inflammation of liver in human throughout the world and assigned the letter A, B, C, D, E and G. Out of these, Hepatitis E, caused by Hepatitis E virus (HEV), currently categorized as a member of the genus Hepevirus in the family Hepeviridae. Hepatitis E is considered highly significant, on account of its predominance in both developed and developing nations, due to poor sanitation and cleanliness condition related to drinking water. This review focuses on general epidemiological study update of hepatitis E virus in India and rest of Asia for the selected period and also throws light on some diagnostic approaches available for the same. An extensive literature search was performed with published work and search in PubMed using term “HEV” combined with “country name” restricting the search publication between year 2008 to 2018 for India and 2013 to 2108 for the rest of Asia. The data was analyzed in detail to meet the requirements of the objectives. Study showed that in India the major causes of Hepatitis E was water contaminated with fecal matter. Reports from East and Southeast Asia signified the role of animal reservoir especially the pigs for HEV. Whereas in Indian neighboring countries like Nepal, Pakistan and Western Asia the major cases of Hepatitis E were associated with blood transfusion and pregnancy related cases. Majority of the diagnostic approaches used in India at medical facilities are based on anti-HEV IgM detection. However, the molecular based approaches played very crucial role in HEV detection. It is observed that the incidence of HEV is gradually expanding and its objective range is not only just developing countries, but also showing an enhancement. In overall, there is need for improvements in detection of HEV disease and methodologies used for the development of HEV vaccines.
