Background Information
4.4 Million Americans are living with chronic hepatitis, which includes an estimated 80,000 Arizonans living with hepatitis C.
75% of those with hepatitis are unaware of the infection
Viral hepatitis is one of the most common infectious diseases in Arizona
Hepatitis C is the leading cause of liver cancer and liver transplants

Hepatitis C What is Hepatitis C?
Inflammation of the liver caused by the Hepatitis C Virus (HCV) Bloodborne pathogen Acute and chronic forms
How is it transmitted? Injection drug use Blood transfusion or organ transplant (before 1992) Recipient of clotting factor concentrates (made before 1987) Needle sticks or sharp instrument exposures Sharing items such as razors or toothbrushes with an infected person
![Page 6: Hepatitis C Rapid Antibody Testing Among At-Risk Populations, Arizona, 2014 Felicia McLean Public Health Associate Office for State, Tribal, Local and.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d775503460f94a596c8/html5/thumbnails/6.jpg)
Hepatitis C Symptoms
• Only 10-25% have symptoms when first infected– Fever– Fatigue– Loss of appetite– Nausea– Vomiting– Abdominal pain– Dark urine– Clay-colored bowel movements– Joint pain– Jaundice (yellow color in the
skin or eyes)
• Usually no symptoms until (or unless) the liver is seriously damaged – may be 10 to 30 years after
infection• More rapid progression may
occur if coinfected with HIV

Who Should be Tested? Anyone born between 1945-1965 Injection drug users- past or present Anyone who received a blood transfusion before 1992 HIV positive persons Recipients of non-professional tattoos or piercings Born to a mother with hepatitis C Abnormal liver test Health care workers

U.S. Preventive Services Task Force (USPSTF) Final Recommendation
Screening for Hepatitis C Virus Infection in Adults Adults at high risk for hep C infection should be screened Health care professionals should offer 1-time hep C screening to adults
born b/w 1945 and 1965 Make up 75% of all people infected in the U.S. This age group at highest risk than other age groups
Became available free of cost as a preventive service for individuals under the Affordable Care Act in June 2014
Available upon request to many people with health insurance, including Medicare

Preliminary Analysis, 2014
• 215 HCV rapid tests were conducted– 43 were HCV rapid positive
• 39 patients were referred for confirmatory testing– 16 confirmatory tests were conducted
» 6 were HCV confirmed cases and were referred to healthcare

Conclusion
Preliminary analysis indicates a high HCV seroprevalence among IDUs, intranasal drug users, and incarcerated individuals
Continuum of HCV care is sub-optimal Only 41% of reactive clients received a confirmatory PCR test Although all 6 HCV confirmed clients were linked to care, there is
limited resources to obtain data on PCR confirmatory test results and to monitor the full continuum of care
Although HCV rapid testing was targeted towards IDUs, a high percentage of reactive clients were those ages 45-64

Implications Continue to test at-risk populations
Baby boomers Injection drug users and intranasal drug users Incarcerated individuals (past and present)
Develop resource directory Local Hepatologists/GI Specialists Federally Qualified Health Centers
Increase public and provider knowledge CDC Recommendations Fact sheet
Support the need to fund future testing programs Promote the National Viral Hepatitis Action Plan objectives
• Increase the proportion of persons living with HCV infection who are made aware of their HCV infection status by testing high-risk populations
