How is Hepatitis B primarily transmitted?

Hepatitis B is primarily transmitted through blood or bodily fluids, making the blood-borne or sexually transmitted route the correct answer. This virus is highly infectious and can be spread through contact with infected blood, which can occur through sharing needles, accidental needle sticks, and exposure to open sores. It is also spread through sexual contact, where bodily fluids can transmit the virus between partners.

The fecal-oral route typically refers to other types of hepatitis, such as Hepatitis A, which is commonly spread through ingesting contaminated food or water. Contaminated food and water are not associated with Hepatitis B transmission. Similarly, while airborne particles can transmit some diseases, Hepatitis B is not transmitted this way; it does not spread through coughing, sneezing, or being in close proximity to an infected individual. Understanding these transmission routes is crucial in prevention efforts, especially in healthcare settings and among high-risk populations.
