HBV is most commonly spread through which routes?

• A. Unprotected sex and sharing needles
• B. Airborne droplets
• C. Water contact
• D. Direct skin friction only

Answer: (A)

HBV is a bloodborne virus, so it spreads most efficiently when someone is exposed to infected blood or other infectious body fluids that can reach the bloodstream or mucous membranes. The two most common routes are unprotected sex and sharing needles, because both involve contact with blood or fluids that can enter through mucous membranes or broken skin. Airborne droplets, water contact, or only direct skin friction don’t provide the typical pathways for HBV transmission—intact skin is a barrier, and HBV isn’t spread through casual contact or respiratory droplets. Vaccination is the best protection, and standard precautions reduce risk in healthcare settings.
