Summary
Hepatitis B virus (HBV) infection affects nearly 8% of a rural Thai village, with higher prevalence in adult males. Malaria prophylaxis programs may contribute to HBV exposure dynamics.
Area of Science:
- Hepatology
- Infectious Diseases
- Epidemiology
Background:
- Hepatitis B virus (HBV) poses a significant global health challenge.
- Understanding HBV transmission in rural settings is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of Hepatitis B surface antigen (HBsAg) and antibodies in a rural Thai village.
- To explore potential factors influencing HBV transmission dynamics, including gender and malaria prophylaxis.
Main Methods:
- Cross-sectional serosurvey conducted in a rural Thai village.
- Assessed prevalence of HBsAg and HBV antibodies.
Main Results:
- Hepatitis B surface antigen (HBsAg) prevalence was approximately 8%.
- Antibody prevalence reached approximately 35%.
- HBsAg prevalence was significantly higher in adult males compared to adult females.
Conclusions:
- HBV infection is prevalent in this rural Thai population.
- Gender-based differences in antigenaemia suggest distinct transmission dynamics.
- Malaria prophylaxis programs may be associated with significant HBV exposure.
