Hepatitis C Needlestick Exposure: Risk, PEP & Next Steps

Yes, a needlestick with HCV-contaminated blood can transmit hepatitis C. Transmission risk per percutaneous exposure: ~0.2–1.8% (average ~0.5–1%). Risk factors: deep injury, hollow-bore needle, visible blood on device, high source viral load, arterial/venous puncture.

HCV is NOT spread by: casual contact, hugging, kissing, sharing food/utensils, coughing, sneezing, food, water, or breastfeeding (unless nipples cracked/bleeding).

After a Needlestick/Sharps Exposure

1. Immediate first aid: Wash wound with soap and water. Flush mucous membranes with water/saline. Do NOT squeeze/bleed the wound.
2. Report immediately to occupational health/ED/supervisor per protocol.
3. Source patient testing: Rapid HCV RNA (preferred) or anti-HCV with reflex RNA. Also HIV, HBV.
4. Exposed person baseline testing: HCV RNA, anti-HCV, ALT, HIV, HBV serology.
5. Post-Exposure Prophylaxis (PEP): No approved antiviral PEP for HCV. Unlike HIV, we don't give preventive antivirals. Instead: early detection → early cure.
6. Follow-up testing: HCV RNA at 3–6 weeks, 3 months, 6 months. Anti-HCV at 4–6 months. If RNA+ at any point → refer for DAA treatment (curative).

Why No Antiviral PEP?

DAAs are so effective (>95% SVR) and well-tolerated that treating early established infection is preferred over prophylactic treatment of potentially uninfected people. Studies show early treatment (within weeks) achieves same cure rates as chronic infection treatment.

Prevention Is Best

• Safety-engineered devices (retractable needles, needleless systems)
• No recapping needles
• Sharps containers at point of use
• Standard precautions always
• HCV treatment as prevention (treat source patients)

Occupational HCV transmission is rare but real. Rapid testing and early cure are the modern standard.
