How do Hepatitis B and C differ from Hepatitis A in terms of transmission?

Hepatitis B and C are primarily transmitted through blood, making them classified as bloodborne viruses. This means that transmission typically occurs through direct contact with infected bodily fluids, such as through sharing needles, sexual contact, or from mother to child during childbirth. In contrast, Hepatitis A is transmitted through the fecal-oral route, which usually occurs when a person ingests contaminated food or water or comes into direct contact with the feces of an infected person. The distinction between these modes of transmission is critical for understanding prevention strategies and public health measures, as it allows individuals to take effective precautions against the diseases. The option accurately highlights these differences in transmission pathways, establishing why this response is correct.
