Hepatitis B primarily spreads through which of the following?

Hepatitis B is primarily transmitted through blood and other body fluids, making this answer particularly accurate. The virus is highly infectious, and its transmission can occur through several routes, including unprotected sexual contact, sharing of needles among intravenous drug users, and exposure to infected blood through injuries or cuts. This mode of transmission highlights the importance of preventive measures such as vaccination, safe sex practices, and avoiding sharing personal items that may come into contact with blood.

The other choices are not mechanisms for the transmission of Hepatitis B. Airborne particles typically relate to respiratory diseases, contaminated food is associated with gastrointestinal infections, and insect bites are a route for other diseases but not for Hepatitis B. Understanding the specific routes of transmission is crucial in both preventing the spread of the virus and implementing effective public health strategies.
