Definitions
� Control:¡ The reduction of disease incidence, prevalence, morbidity or mortality
to a locally acceptable level as a result of deliberate efforts; continued intervention measures are required to maintain reduction. Example: diarrheal diseases
� Elimination:¡ Reduction to zero of the incidence of infection caused by a specific
agent in a defined geographical area as a result of deliberate efforts; continued measures to prevent re- establishment of transmission are required. Example: measles, poliomyelitis.
� Eradication¡ Permanent reduction to zero of the worldwide incidence of
infection caused by a specific agent as a result of deliberate efforts; intervention measures are no longer needed. Example: Smallpox

Feasibility Criteria for Elimination
In General1 Hepatitis C Virus Check list
No non- human reservoir and the organism can not multiply in the environment
No human reservoir
There are simple and accurate diagnostic tools
Serology widely available
Practical interventions to interrupt transmission
Treatment as preventionNeedle exchange programs
Opioid substitution programs
The infection can in most cases be cleared from the host Treatment is 95 % curative

Essential Goals to Eliminate HCV
� Prevent sequelae of advancing liver disease in those already infected¡ Baby Boomers, born 1945 -1965
� Prevent new or “incident” infections¡ Persons who inject drugs¡ Unsafe healthcare practices¡ Sexual exposures in Immunocompromised individuals

Why is HCV Elimination Needed in CNHS?
� Higher prevalence than US population ¡ Estimated > twice the national prevalence
� ~ 4158 AI/AN patients in the CNHS are estimated to be chronically infected with HCV¡ ~1247 will develop cirrhosis¡ ~50 will develop liver cancer¡ Ongoing transmission is occurring at an unknown rate
� At the present time we can deliver curative treatment to >90% of patients
AI/AN: American Indians/Alaskan Natives

Goal # 2ExpandScreening Program
� CDC guidelines for Hepatitis C testing
÷ Baby boomers (born from 1945-1965)
÷ Current or past injection drug users
÷ Certain medical conditions (high ALT, HIV, HD, transfusion/transplant prior to1987/1992)
÷ Recognized exposure: healthcare workerincident or child born to HCV infectedmother
Are the age and risk targetedscreening guidelines applicable to
the CNHS population?

age group who access theCNHS
� Expand screening sites¡ ED/UC, dental, behavioral
health

Decreasing Transmission of HCV
Objective Outcome
Education Public campaign developed by OSHD
Harm Reduction
Pharmacological Substitution Weekly ECHO addiction clinic started
Syringe/NeedleExchange Discussion with legislature ongoing
Behavioral Health Same day consultation established
Treatment as prevention-PWID are offered treatment
-Reinfections are being monitored
Acute HCV surveillance Contact tracing program started August 2016

Conclusions
� Elimination of HCV is possible but not effortless
� The tools for elimination are available
� HCV elimination will need the involvement of political leaders, policy makers, public health officials, medical providers, scientists, epidemiologist and activists from the community
