How is Hepatitis A primarily transmitted?

Hepatitis A is primarily transmitted through the faecal-oral route. This mode of transmission occurs when a person ingests food or water contaminated with the feces of an infected individual. The virus can spread easily in environments with poor sanitation and hygiene practices, where contamination of food and water supplies can occur.

Transmission through the faecal-oral route highlights the importance of basic hygiene measures, such as handwashing, particularly in communities where outbreaks are more likely to occur. Hepatitis A is not typically spread through blood contact, sexual transmission, or vertical transmission from mother to child during childbirth, making faecal-oral the defining route for its spread.
