Common Bloodborne Pathogens:
Hepatitis C Virus (HCV):
HCV is primarily transmitted through needle sticks, cuts, or blood to the eyes. While the infection rate following a percutaneous injury is relatively low (approximately 1.8%) , HCV remains a serious concern as it is a leading cause of liver transplantation in the U.S. Unlike Hepatitis B, there is currently no vaccine for HCV. Treatment often involves expensive antiviral medications that can have significant side effects.
Human Immunodeficiency Virus (HIV):
The risk of HIV transmission after a needle stick is estimated at 0.3%. This risk increases if the source patient has a high viral load or if the injury involves a hollow-bore need;e used in a vein or artery. Post-exposure prophylaxis (PEP) with specific antiretroviral medications is recommended and should be started as soon as possible, typically continuing for four weeks.
Hepatitis B Virus:
HBV is highly infectious, with transmission rates following a needle stick ranging from 6% to 62% in unvaccinated individuals. Fortunately, the widespread vaccination of healthcare workers has significantly reduced occupational transmission.
Immediate Post-Exposure Actions:
If an exposure occurs, immediate action is vital:
- Wash: Clean cuts and needle sticks with soap and water
- Flush: Irrigate splashes to the nose, mouth, or skin with water
- Irrigate: Use clean water or saline for splashes to the eyes
Report: Notify the appropriate department (e.g., Employee Health or Infection Control) immediately. Prompt reporting is essential for timely prophylaxis.
