Which of the following hepatitis types has an oral-fecal route of transmission?

Hepatitis A is the type of hepatitis that is primarily transmitted via the oral-fecal route. This mode of transmission typically occurs when a person ingests food or water contaminated with the feces of an infected individual. Hepatitis A is often associated with poor sanitation and hygiene practices, making it more likely to spread in areas with inadequate sanitation or during outbreaks in communal living situations.

In contrast, Hepatitis B and Hepatitis C are mainly transmitted through blood and bodily fluids, such as sexual contact or sharing needles. Hepatitis D is dependent on Hepatitis B for its transmission, relying on similar routes as Hepatitis B. Therefore, Hepatitis A stands out as the only type that follows the oral-fecal transmission pathway, which is why it is the correct answer in this context. Understanding the modes of transmission is crucial for prevention and control of hepatitis infections.
