What is the primary mode of transmission for Hepatitis B?

Hepatitis B is primarily transmitted through exposure to infected bodily fluids. This includes blood, semen, and other fluids from an infected individual. The virus is highly infectious and can be spread through activities such as unprotected sexual contact, sharing needles or syringes, and from mother to child during childbirth. The presence of the virus in bodily fluids is a crucial factor in understanding its transmission, as it highlights the importance of safe practices in healthcare settings and personal behavior to prevent the spread of the infection.

Other transmission routes like airborne particles, contaminated water, and insect bites do not play a role in the transmission of Hepatitis B. The virus is not spread through casual contact, respiratory droplets, or environmental sources, which reinforces why understanding the specific modes of transmission related to bodily fluids is essential in controlling and preventing Hepatitis B infections.
