Which types of hepatitis are transmitted through person-to-person contact?

The correct answer highlights that hepatitis B, C, and D are transmitted primarily through person-to-person contact. Hepatitis B is spread through contact with infectious body fluids, such as blood, semen, and other bodily fluids, making it highly transmissible through sexual contact, sharing needles, or from mother to child during childbirth.

Hepatitis C is also primarily spread through similar means, particularly through blood-to-blood contact, which often occurs in settings like intravenous drug use. Chronic infection can result in severe liver damage over time.

Hepatitis D, on the other hand, is unique because it requires the presence of hepatitis B to replicate and cause infection in the host. Consequently, it can only spread in individuals who are already infected with hepatitis B.

In contrast, hepatitis A and hepatitis E are primarily transmitted through the fecal-oral route and are commonly associated with contaminated food and water, rather than direct person-to-person contact. This distinction is critical in understanding the modes of transmission for different types of hepatitis and highlights why the chosen answer accurately reflects the nature of transmission for hepatitis B, C, and D.
