What is one of the primary methods of transmission for Hepatitis E?

Hepatitis E primarily spreads through the faecal-oral route. This transmission occurs when a person ingests food or water contaminated with the feces of an infected individual. This route is particularly significant in areas with inadequate sanitation and hygiene practices. Vertical transmission, which can also occur, refers to the transmission of the virus from a mother to her child during pregnancy or at birth, although this is less common and not the primary route of infection.

The faecal-oral transmission is especially crucial in understanding the epidemiology of Hepatitis E, as outbreaks often happen in times of natural disasters or in regions with poor water quality. This knowledge is vital for public health measures aimed at preventing outbreaks, especially in vulnerable communities where clean water supply may be compromised.

Other transmission methods, such as blood transfusions and sharing needles, are not typical ways that Hepatitis E is spread. The virus is generally not transmitted through sexual contact or breast milk either. Therefore, identifying faecal-oral transmission as a primary route highlights both the nature of the virus and the necessary strategies for prevention, such as improving sanitation and health education.
