Blood and blood components are the main vehicles for occupational transmission of HBV. Which of the following best describes this statement?

• A. Blood and blood components
• B. Airborne droplets
• C. Water
• D. Food

Answer: (A)

HBV is a bloodborne pathogen, so infection in occupational settings mainly happens when infectious blood or blood-containing materials enter the body. This typically occurs through percutaneous injuries with contaminated needles or other sharp instruments, or through splashes to broken skin or mucous membranes. Airborne droplets, water, and food are not typical routes for HBV transmission in the workplace, which is why describing blood and blood components as the main vehicles best fits how transmission occurs in occupational environments. This underscores the importance of protective practices, proper sharps handling, and vaccination to prevent HBV infection.
