Key points
- Talk to all your patients, especially those who use or inject drugs, about getting vaccinated against hepatitis A and hepatitis B and getting tested for hepatitis B and hepatitis C.
- Syringe services programs (SSPs) play an important role in reducing the transmission of viral hepatitis, human immunodeficiency virus (HIV), and other infections among people who inject drugs (PWID).
Risks
Certain populations, including people who use or inject drugs, have an increased risk for contracting viral hepatitis.
Injection drug use and hepatitis A
Hepatitis A is transmitted through the fecal-oral route. While hepatitis A can affect anyone, certain groups are at greater risk for infection. Recent person-to-person transmission of hepatitis A has occurred across the country, and frequently among people who use drugs (PWUD). In some cases, people can experience severe complications, hospitalization, and even death. CDC recommends that people who use or inject drugs be vaccinated against hepatitis A.
Vaccinate for hepatitis A
Injection drug use and hepatitis B
Hepatitis B virus (HBV) is a bloodborne pathogen and can also be transmitted through exposure to other body fluids. PWID are at risk for HBV infection through the sharing of syringes and/or any other equipment used to prepare and inject drugs.
CDC published updated recommendations for hepatitis B screening and testing in 2023 that are complementary to the 2022 Advisory Committee on Immunization Practices (ACIP) vaccine recommendations for hepatitis B.
The updated recommendations include hepatitis B screening for all adults once in their lifetime and hepatitis B vaccination for all adults aged 19-59 years.
Vaccinate for hepatitis B
Injection drug use and hepatitis C
Hepatitis C virus (HCV) is also a bloodborne pathogen. The number of acute hepatitis C cases has doubled since 2015. Among risk behaviors and exposures identified for reported cases of acute HCV infection in 2022, injection drug use was most commonly reported. CDC recommends one-time screening for all adults, testing for anyone who has ever injected drugs, regardless of age, and periodic testing if risk persists.
Harm reduction
SSPs are community-based prevention programs. The purpose is to:
- Increase access to harm reduction services for people who use or inject drugs or have a history of injecting drugs.
- Reduce the incidence of infectious disease and other complications of using injection drugs.
These organizations provide a range of harm reduction services including:
- Access to sterile syringes and disposal of used injection equipment.
- Testing and vaccination for infectious diseases.
- Linkage to treatment for infectious diseases.
- Linkage to treatment for substance use disorder.
SSPs are associated with an estimated 50% reduction in HIV and HCV incidence.
Nearly 30 years of research show that comprehensive SSPs are safe, effective, and cost-saving, do not increase illegal drug use or crime, and play an important role in reducing the transmission of viral hepatitis, HIV, and other infections.
