What is the primary mode of transmission for Hepatitis B?

  1. Fecal-oral contamination

  2. Blood, sex, saliva, urine, and breast milk

  3. Direct contact with infected skin

  4. Airborne particles

The correct answer is: Blood, sex, saliva, urine, and breast milk

Hepatitis B is primarily transmitted through exposure to infectious body fluids. This includes blood, sexual contact, saliva, urine, and breast milk. The virus can be present in any of these fluids, but it is most commonly spread through blood and sexual contact. In the context of the other options, fecal-oral contamination is associated with viruses such as Hepatitis A, which is not the case for Hepatitis B. Direct contact with infected skin typically pertains to infections like herpes or staph, rather than Hepatitis B. Airborne particles are commonly linked to respiratory infections, and Hepatitis B is not transmitted through the air. Understanding these distinctions is crucial for recognizing how to prevent the transmission of Hepatitis B effectively.
