How is Hepatitis B primarily transmitted?

1. Through respiratory droplets

2. Through insect bites

3. Through blood and body fluid transmission

4. Through contaminated water

The correct answer is: Through blood and body fluid transmission

Hepatitis B is primarily transmitted through blood and body fluid transmission. This includes exposure to infected blood, which can occur through activities such as sharing needles or syringes, receiving contaminated blood products, or through open sores or cuts. Additionally, Hepatitis B can be spread through sexual contact with an infected person, as the virus is present in bodily fluids including semen and vaginal secretions. The nature of Hepatitis B's transmission emphasizes the importance of practicing safe behaviors, such as using barrier methods during sexual activity and not sharing personal items that may come into contact with blood, like razors or toothbrushes. Understanding this mode of transmission helps healthcare workers and individuals take appropriate preventative measures against infection. Other options relate to modes of transmission that are not relevant for Hepatitis B. For example, respiratory droplets are typically associated with viruses that affect the respiratory tract, insect bites are more relevant for diseases spread by vectors, and contaminated water is a factor in waterborne diseases rather than bloodborne viruses like Hepatitis B.
