Spread through blood or bodily fluids.

• A. Airborne Transmission
• B. Bloodborne Transmission
• C. Vector Borne Transmission
• D. Sexual Transmission

Answer: (B)

Bloodborne transmission occurs when blood or other infected bodily fluids enter another person’s body, typically through percutaneous exposure such as needle sticks or cuts, or through mucous membranes or open wounds contacting those fluids. This route is responsible for infections like hepatitis B, hepatitis C, and HIV, which is why safety guidelines emphasize universal precautions, proper sharps handling, and immediate spill cleanup with appropriate disinfectants. It differs from airborne transmission (spread through inhalation of droplets or aerosols in the air), vector-borne transmission (requiring a living carrier like mosquitoes), and sexual transmission (spread via sexual contact involving bodily fluids). The description focusing on spread through blood or bodily fluids best matches the bloodborne route.
