HIV and HBV are examples of which category of hazards?

• A. Bloodborne pathogens
• B. Airborne pathogens
• C. Chemical hazards
• D. Surface contaminants

Answer: (A)

How a pathogen is transmitted defines its hazard category. HIV and HBV are transmitted mainly through blood and certain body fluids, so they are classified as bloodborne pathogens. This classification matters because it guides the protective measures used: universal precautions, gloves and other PPE, safe handling of needles and sharps, vaccination for HBV, and post-exposure protocols. They aren’t airborne pathogens, which spread through inhalation of aerosols (like TB or influenza). They aren’t chemical hazards, which involve toxic chemicals rather than infectious organisms, and they aren’t simply surface contaminants, which refers to residues rather than the transmission route. So the category that best fits HIV and HBV is bloodborne pathogens.
