The majority of hepatitis C infections result from people sharing needles or other equipment used to inject drugs. However, some people do become infected with hep C through anal sex. This risk increases for people who have an STD and are exposed to hep C. Sharing equipment used to snort drugs can also pose a risk for hep C. For people on PrEP we recommend testing for hepatitis C once a year. It sounds like you are potentially at risk for hepatitis C and that you should get tested. If you do have Hep C, there are great treatments that can cure Hepatitis C in 8-12 weeks.
