Prevention and Control of Viral Hepatitis in Correctional Settings

An Update

on National Recommendations


Slide2 l.jpg

Why Intervene in Correctional Settings?

Its where the disease is!

  • Thousands of former inmates return to the community each month

    • Correctional health programs provide the opportunity to make prevention and health care services available to a segment of the community with disparities in health outcomes


Adult correctional population united states l.jpg
Adult Correctional Population United States

  • Annually, about 6.5 million adults are in prison, jail, probation and parole

  • Represents about 3.1% of the adult US population -- 1 in every 32 adults

  • About 30% of persons in the correctional system are incarcerated (~1.9 million)

The A, B, Cs of Viral Hepatitis States, 1996

  • Hepatitis A

    • fecal-oral, spread: person-to-person, drug use, men having sex with men, travelers, day care, food

    • vaccine-preventable

  • Hepatitis B

    • blood and body fluids: sex, drugs, perinatal, occupational, nosocomial

    • vaccine-preventable

  • Hepatitis C

    • blood: drugs, sex, perinatal, nosocomial, occupational

    • NOT vaccine-preventable

Hepatitis B


Immunization recommendations to eliminate hbv transmission in the united states l.jpg
Immunization Recommendations to Eliminate HBV Transmission in the United States

  • Maternal screening to prevent perinatal infection

  • Universal vaccination of infants

  • Catch-up vaccination of adolescents

    • previously unvaccinated at 11-12 years of age

    • high risk

  • Adults at high risk of infection

Hepatitis b immunization recommendations l.jpg
Hepatitis B Immunization Recommendations in the United States

  • “High-risk groups for whom vaccination is recommended include:

    Inmates of long-term correctional facilities. Prison officials should consider undertaking screening and vaccination programs directed at inmates with histories of high-risk behaviors.”

Missed Opportunities for Immunization Against Hepatitis B Virus Infection

  • 39% have been previously incarcerated

  • 2% were incarcerated during their incubation period

  • 70% of IDUs were previously incarcerated

Hepatitis b vaccination programs in prisons l.jpg
Hepatitis B Vaccination Programs in Prisons Virus Infection

  • National Survey – 50 States and FBOP

    • 35 respondents, 77% of incarcerated adults

  • Results

    • 2 states offer vaccine to all incoming prisoners

    • 25 states and FBOP offer vaccine to some

    • 9 states offer no vaccine

  • Barriers

    • Cost of vaccine

    • 25 states would offer routine vaccination if funds available

Effect of Hepatitis B Vaccination of Juveniles, Virus Infection

Hampden County, MA

  • Massachusetts began vaccinating juvenile detainees in 1996

    • 1% refuse, 43% completed 3 doses

  • Of entering jail inmates in 2000

    • Vaccine immunity

      • 20 year olds = 40%

      • 40-49 year old = <5%

    • HBV infection

      • 20 year olds = 7%

      • 40-49 year olds = 35%

Hepatitis B Vaccination of Incarcerated Persons Virus Infection

  • Recommended since 1982

  • Prevents infection outside and inside of facilities

  • Feasible

  • Cost-effective

  • Anticipated impact on the entire community

  • A number of challenges to implementation

    • Juveniles = covered under Vaccines for Children (VFC) program

    • Adults = no national programs

Recommendations to Identify Persons with HCV Infection Virus Infection

  • Identify persons at risk for HCV and test to determine infection status

    • Identify at-risk persons through history, record review

  • Provide HCV-positive persons

    • Medical evaluation and management

    • Counseling

      • Prevent further harm to liver

      • Prevent transmission to others

Preliminary Recommendations: Virus Infection

Prevention and Control of Viral Hepatitis

in Correctional Settings


Proposed recommendations hepatitis b l.jpg
Proposed Recommendations-Hepatitis B Virus Infection

    • Immunize women not previously vaccinated

  • Vaccinate ALL incarcerated persons

    • Regardless of length of incarceration

    • Initiate upon entry for all who receive medical evaluation

  • Pre-vaccination screening

    • Consider if cost effective


Proposed recommendations hepatitis b30 l.jpg
Proposed Recommendations-Hepatitis B Virus Infection

  • Initiate complete series for ALL incarcerated persons - regardless of ability to ensure completion

    • First dose protects ~40% of people

    • Second dose protects ~75%

  • Develop mechanisms to complete vaccination series

    • Tracking within the facility/system

    • Referrals into community health care


Proposed recommendations hepatitis c l.jpg
Proposed Recommendations-Hepatitis C Virus Infection

  • All incoming inmates should have an assessment of risk-factors for infection

  • All inmates at risk for infection should be tested for anti-HCV


Proposed recommendations hepatitis c32 l.jpg
Proposed Recommendations-Hepatitis C Virus Infection

  • Inmates with chronic HCV infection should be evaluated for liver disease

  • Treatment should be offered to persons who meet criteria of current NIH Consensus Guidelines and be conducted in consultation with a specialist

  • HCV infected persons who abuse substances should be offered substance abuse treatment


Health education post release management l.jpg
Health Education & Post-Release Management Virus Infection

  • Viral hepatitis should become part of comprehensive health education and risk reduction program

  • Consider offering as part of HIV curriculum

  • Necessary Components:

    • How to prevent acquiring infection

    • Where to go for vaccine series completion

    • For infected persons

      • How to prevent infecting others

      • How to prevent further liver damage
