Hepatitis B, C, and HIV are most prevalent.

• A. Common Bloodborne Pathogens
• B. Bloodborne Pathogens
• C. Pathogenic Viruses
• D. Fungal Diseases

Answer: (B)

The key idea is how World of Safety guidelines categorize infectious agents by their route of transmission. Hepatitis B, hepatitis C, and HIV are transmitted through blood (and certain body fluids), so they’re grouped together as bloodborne pathogens. This classification is used to shape protective practices in athletic training facilities—universal precautions, appropriate PPE, vaccination for Hepatitis B, and procedures for handling exposures. The other options aren’t the standard label: “common bloodborne pathogens” isn’t a formal category, “pathogenic viruses” is too broad and includes viruses not transmitted via blood, and “fungal diseases” are not the primary concern for bloodborne exposure.
