Among bloodborne pathogens, which is the MAJOR OCCUPATIONAL RISK for healthcare workers?
Show answer and explanation
Correct answer: C. Hepatitis B (6–30% per needlestick) — MAJOR risk
✓ C) Hepatitis B is the major occupational risk — same reasoning as Q20.
Hepatitis B remains the #1 occupational infection risk for dental workers: 30× more infectious than HIV per needlestick exposure. Survives on dried blood for 7+ days. This is why HBV vaccine (3-dose series + titer check) is MANDATORY for all dental workers and is required by OSHA. After needlestick: check titers, give HBIG + vaccine booster if non-immune, report injury, document. Note: The risk order is HBV > HCV > HIV — this is THE most tested occupational transmission fact in dental boards.
