Question: 1 / 400

How is Hepatitis B virus primarily transmitted?

Through contaminated food and water

Through respiratory droplets

Through body fluids like blood and semen

Hepatitis B virus (HBV) is primarily transmitted through body fluids, particularly blood and semen. This mode of transmission reflects the virus's primary reservoirs, often found in high concentrations in these fluids. Activities such as sharing needles, unprotected sexual contact, and from mother to child during childbirth are common ways the virus spreads.

Contaminated food and water do not play a role in Hepatitis B transmission, as the virus is not typically spread through the gastrointestinal route. Similarly, respiratory droplets are associated with viruses that cause respiratory infections, not Hepatitis B. Insects and animal bites are also not known pathways for HBV transmission, further emphasizing that body fluids are the primary vectors for spreading this virus. This understanding is crucial for implementing effective preventive measures in clinical practice.
