Hepatitis C virus (HCV) is primarily transmitted through which route?
Show answer and explanation
Correct answer: B. Blood (percutaneous)
HCV is primarily transmitted through blood — sharing contaminated needles, blood transfusions (pre-1992), and needlestick injuries in healthcare workers. Unlike Hep B, sexual transmission for HCV is low efficiency.
- A. Sexual contact is the predominant route for HBV; for HCV it is a minor, low-efficiency route.
- B. CORRECT. Blood/percutaneous is the primary route for HCV. Needlestick injuries are the occupational concern for dental workers.
- C. Fecal-oral is the route for Hepatitis A (and E) — not HCV.
- D. Respiratory droplets transmit respiratory viruses — not HCV.
