Testing and Linking Foreign-Born People with Chronic Hepatitis B Virus Infection to Care at Nine US Programs, 2012-2014

Objective. Hepatitis B virus (HBV) infection continues to be a public health threat in the United States. As many as 2.2 million people are infected, approximately 70% of whom are foreign-born, and fewer than one-third are aware of their infection. We launched an HBV testing and linkage-to-care initiative among foreign-born people. Methods. As part of the Hepatitis Testing and Linkage to Care (HepTLC) initiative, which promoted viral hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites, nine U.S. programs in seven states conducted HBV screening from October 2012 to September 2014. The nine programs partnered with health-care centers and community-based organizations to recruit foreign-born people recommended for HBV testing. We assessed patient characteristics, region of origin, risk factors, hepatitis B surface antigen (HBsAg) status, and referral to medical care. Results. Of 23,144 participants tested for HBV, 1,317 (5.7%) were HBsAg positive. Of these, the median age was 47 years, 1,205 (91%) had at least one risk factor for HBV infection, 1,117 (85%) received posttest counseling, 1,098 (83%) were referred to care, and 606 (46%) attended a first medical appointment. The proportion of HBsAg-positive participants by region of origin included Africa (10%, 206/2,129), Western Pacific (6%, 616/9,673), Eastern Mediterranean (5%, 174/3,337), Southeast Asia (5%, 191/3,891), South America (2%, 6/252), Eastern Europe (2%, 6/262), and North America (1%, 17/1,936). Conclusion. Community-based HBV testing initiatives can identify substantial numbers of people with chronic HBV infection, inform them of their infection status, and provide posttest counseling and linkage to care. However, strategies are needed to improve linkage to HBV-directed medical care for foreign born individuals living with chronic HBV infection.
