How is Hepatitis B primarily transmitted?

Hepatitis B is primarily transmitted through direct contact with infected blood or body fluids. This includes exposure during activities such as sexual contact, sharing needles, or from mother to child during childbirth. The virus is highly contagious, and even small amounts of blood can transmit the infection. This mode of transmission is why Hepatitis B is particularly concerning in medical settings, among individuals who use injectable drugs, and in certain populations where sexual transmission is more prevalent.

Transmission through food and water is not a concern for Hepatitis B, as it is not spread through casual contact or consumption. Options like respiratory droplets and insect bites are also not associated with the transmission of Hepatitis B. Understanding this route of transmission is critical in implementing effective strategies for prevention and control, such as vaccination and safe practices in healthcare settings.
