What is the primary method of transmission for hepatitis B?

The primary method of transmission for hepatitis B is through direct contact with blood. Hepatitis B is a viral infection that is most often spread when blood from an infected person enters the body of someone who is not infected. This can happen through activities such as sharing needles, unprotected sexual contact, or from mother to child during childbirth. Understanding this mode of transmission is crucial for implementing effective prevention strategies, especially in healthcare settings where exposure to blood is more likely.

Other transmission methods, such as airborne, vectorborne, or droplet transmission, are not applicable to hepatitis B. Airborne transmission typically refers to diseases that spread through respiratory particles over distances, while vectorborne diseases are transmitted through bites from insects or other carriers. Droplet transmission involves larger respiratory droplets that do not remain suspended in the air and typically affects respiratory conditions rather than viral infections like hepatitis B.
