Performance results of Community-Based Proactive Screening of Hepatitis B and C Infection Among At-Risk Populations under Collaboration with Local Administrative Organizations in Health Region 4

Abstract

This cross-sectional descriptive study aimed to examine the performance of community-based proactive screening for hepatitis B and C infections among at-risk populations under the collaboration with local administrative organizations in Health Region 4, Thailand. The sample comprised 2,207 individuals aged 30 years and older whose screening data were recorded in the national hepatitis B and C screening database maintained by the Division of AIDS and STIs, Department of Disease Control. The results revealed that 2.13% tested positive for hepatitis B surface antigen (HBsAg), and 1.04% tested positive for anti-HCV antibodies. The majority of positive cases were aged 60 years and older (48.94% for HBsAg, 52.17% for anti-HCV) and were born before 1992 (94.00% and 100%, respectively). To enhance the sustainability and effectiveness of hepatitis B and C prevention and control, it is recommended to develop and integrate the screening data system with existing health service platforms, implement continuous and proactive public communication strategies, and ensure adequate resources—including diagnostic kits and budgets—are provided by local administrative organizations across all levels. Additionally, capacity building for local health personnel and community-based staff should be strengthened, particularly in screening, counseling, and referral processes. A follow-up care system using community mechanisms or care coordinators should also be established to ensure long-term disease management and prevention.
