Which hepatitis virus is largely transmitted through fecal contamination?

Hepatitis A is primarily transmitted through fecal-oral contamination, which typically occurs when a person ingests food or water that has been contaminated with the feces of an infected person. This mode of transmission is common in areas with inadequate sanitation or where personal hygiene practices are poor. The virus is also frequently spread through close contact, such as among family members or caregivers of an infected individual.

In contrast, Hepatitis B and Hepatitis C are commonly transmitted through blood and bodily fluids, such as through sexual contact or sharing needles, rather than through contaminated food or water. Hepatitis D requires the presence of Hepatitis B for its transmission, again highlighting that its spread is not linked to fecal contamination but rather to similar routes as Hepatitis B. Thus, Hepatitis A stands out as the only virus among the options listed that is predominantly associated with fecal contamination, which makes it the correct choice in this context.
