5 People Who Inject Drugs: the Core of the Hepatitis C Epidemic Largest group of infected persons Source of most HCV transmission Highest prevalence (50%-90%) Highest incidence (10%-40% per year) Approx. one million people who inject drugs in U.S. have hepatitis C. Few people who inject drugs are in care; even fewer receive treatment.

18 Reaching Newly Affected Groups Prescription Opioid Users Five million young people used pharmaceutical opioids in past year Many are in rural and suburban locations Transition to heroin injection is common Opioid overdoses are epidemic and signal HCV transmission HCV outbreaks reported to CDC in 13 states We can intervene now or watch the epidemic unfold.

19 Effective HCV Prevention Interventions Community-based outreach Education Sterile syringe access Other injection equipment Voluntary testing and counseling Treatment for substance use (buprenorphine) Pharmacy syringe access and education Internet and social media Law enforcement, jails, prisons Multicomponent interventions Harm reduction Peer-driven interventions Financial incentives Antiviral treatment Education to prevent reinfection

21 Reaching Newly Affected Groups Prescription Opioid Users Multicomponent interventions Outreach, education, counseling, testing, linkage to care Test negative prevention Test positive treatment Epidemiology and surveillance simultaneously with providing services We can intervene now or watch the epidemic unfold.

22 Reaching Newly Affected Groups Prescription Opioid Users Collaboration (and cross-training): Federal, state, local public health agencies Harm reduction and outreach experts Hepatitis C specialists Mental health and substance use treatment providers Primary care Pharmacists Law enforcement authorities Criminal justice Affected communities (people using illicit drugs)

23 Reaching Newly Affected Groups Prescription Opioid Users Harm reduction Respect, nonjudgment, cultural competence Persons in target groups are the experts Full collaboration of affected communities in defining and implementing needed interventions

25 Hepatitis C Virus Incidence in Young People Who Inject Drugs The Swan Project, New York, N Person- Days New HCV Infections HCV Incidence per 100 person-years (95% CI) P Sex 0.25 Men , (17.6, 41.4) Women 68 13, (5.5, 31.8) Follow-up (after enrollment) days , (30.1, 82.8) days 148 7, (7.6, 54.0) >120 days , (4.8, 21.3) Total , (14.9, 32.2)

26 Effective Outreach to Hidden Populations Field Methods Community-based locations Environment free of judgment, shame, or stigma Staff knowledgeable about drug use and users and hepatitis C Client-centered focus Services counseling, testing, harm reduction Cash incentives Hard-to-reach populations are easy to reach when programs are designed to meet their needs.

27 Reaching Newly Affected Groups Prescription Opioid Users Antiviral Treatment Everyone who is infected needs access to treatment To prevent disease, treat those at risk of progression To prevent spread, treat those at risk of transmission Governments, payers, and pharmaceutical industry must agree: Everyone who needs antiviral therapy for hepatitis C must have access to it. Education to prevent reinfection

28 Preventing HCV Reinfection after SVR in People Who Inject Drugs Author Year N Reinfections Rate per 100 person-years (95% CI) Backmund (0.5,14) Dalgard (0.0,4.7) Currie (0.1,15) Grebely (0.4,12) Grady (0.0,4.2) Aspinall (0.9,6.1) Choices (NY) Aspinall Clin Infect Dis 2013;57:S80

29 Hepatitis C: Preventing New Infections New regimens offer the promise of eliminating HCV A national consensus is needed to make this happen. Outreach Seek Test Treat Cure Prevent Intervention will require effort and resources. We can intervene now or watch the epidemic unfold.
