What is the primary mode of transmission for Hepatitis B?

The primary mode of transmission for Hepatitis B is through bodily fluids. This includes blood, semen, vaginal secretions, and other body fluids, which may occur through various means such as sexual contact, sharing needles, or from mother to child during childbirth. Understanding this transmission pathway is crucial because it informs prevention strategies, such as safe sex practices, needle exchange programs, and vaccination, which is one of the most effective ways to prevent the spread of hepatitis B. Each of these transmission routes emphasizes the importance of handling bodily fluids with caution in healthcare settings, particularly in mortuary science, where exposure to such fluids can occur.
