Detailed explanation-1: -Hepatitis E virus (HEV) is most commonly transmitted via the fecal-oral route from contaminated water, and large waterborne outbreaks frequently occur, especially in developing countries. Rarely, it can also be a fecally transmitted zoonotic infection. [15] Person-to-person transmission is rare.

Detailed explanation-2: -Geographical distribution. Hepatitis E occurs worldwide. In regions of the world where sanitation may be poor (Asia, Africa, and Central America), the virus spreads by the consumption of sewage-contaminated food and water. The source of contamination is faeces shed from other infected people (or infected animals).

Detailed explanation-3: -Hepatitis A is caused by hepatitis A virus (HAV). Transmission occurs by the fecal-oral route, either by direct contact with an HAV-infected person or by ingestion of HAV-contaminated food or water.
