Which term best describes the category of hazard that includes viruses like HBV transmitted through blood?

• A. Bloodborne pathogens
• B. Airborne pathogens
• C. Waterborne pathogens
• D. Fungal pathogens

Answer: (A)

Bloodborne pathogens describe microorganisms carried in blood that can cause disease and are transmitted through exposure to infected blood. Viruses like hepatitis B (HBV) are classic examples because their transmission occurs through contact with infected blood, such as needlestick injuries, cuts, or open wounds. That makes bloodborne pathogens the best term for this hazard category. The other options refer to different routes of transmission—airborne spreading through respiratory droplets, waterborne through contaminated water, and fungal pathogens involving organisms like molds or yeasts—so they don’t fit the scenario of blood-related transmission. In practice, protecting against bloodborne pathogens involves vaccination where available, appropriate PPE, and controls to minimize exposure to blood and other potentially infectious materials.
