From the Guidelines

Yes, hepatitis can be transmitted through needle stick injuries, with hepatitis B posing the highest risk, followed by hepatitis C. The risk of transmission varies depending on the type of hepatitis virus and the circumstances of the exposure. According to the Centers for Disease Control and Prevention (CDC) 1, the risk of hepatitis B transmission after a needlestick injury involving an HBV-positive source is 23%--62%. For hepatitis C, the risk is lower, but still significant, with a 1.8% chance of infection after a single needle stick exposure to an infected source 2. If you experience a needle stick injury, it is essential to immediately wash the area with soap and water, report the incident to your supervisor if in a workplace setting, and seek medical attention promptly. Post-exposure prophylaxis (PEP) is available for hepatitis B, typically consisting of hepatitis B immune globulin (HBIG) and the hepatitis B vaccine series, ideally started within 24 hours of exposure 1. For hepatitis C, while there is no PEP, early detection through testing at baseline, 4-6 weeks, and 4-6 months post-exposure allows for prompt treatment if infection occurs 2. Key steps to take after a needle stick injury include:

  • Washing the area with soap and water
  • Reporting the incident to your supervisor
  • Seeking medical attention promptly
  • Undergoing post-exposure prophylaxis (PEP) for hepatitis B, if necessary
  • Getting tested for hepatitis C at baseline, 4-6 weeks, and 4-6 months post-exposure. It is crucial to follow these steps to minimize the risk of transmission and ensure prompt treatment if infection occurs.

From the Research

Hepatitis Transmission through Needle Stick Injury

  • Hepatitis can be transmitted through a needle stick injury, as it is a blood-borne disease [(3,4)].
  • The risk of transmission depends on the volume of blood transmitted and the presence of hepatitis B, hepatitis C, or HIV in the source person 4.
  • Post-exposure prophylaxis, such as hepatitis B vaccination and antiretroviral medications, can reduce the risk of transmission [(4,5)].

Prevention Measures

  • Effective measures to prevent infections from occupational exposure to blood include immunization against HBV, eliminating unnecessary injections, and implementing Universal Precautions 5.
  • The use of safer devices, such as needles that sheath or retract after use, and provision of personal protective equipment can also reduce the risk of transmission 5.

Treatment and Management

  • Treatment with direct-acting antivirals, such as ledipasvir/sofosbuvir, can lead to HBV reactivation in patients coinfected with HCV and HBV [(6,7)].
  • HBV virologic reactivation can occur in a majority of patients during treatment and follow-up, but most cases are asymptomatic 7.
