Which is MORE contagious for dental healthcare workers?
Show answer and explanation
Correct answer: B. Hepatitis B (HBV)
Hepatitis B (HBV) is much MORE contagious than Hepatitis C for healthcare workers. A needlestick from HBV+ source = 6-30% infection risk (depending on HBeAg status). HCV needlestick = ~1.8% risk. HIV needlestick = ~0.3% risk. However, HCV has no vaccine, making it clinically concerning. HBV vaccination is mandatory for dental workers.
