Limited data regarding prevalence of hepatitis B virus infection in Timor-Leste exist.Methods
An observational study of hepatitis B surface antigen (HBsAg) results of women delivering at Bairo Pite Clinic in Dili, Timor-Leste was carried out.Results
Of the 781 women included in the study, 80.5% (626/777) of women who had accessed antenatal care had been tested for HBsAg, of whom 2.2% (14/626) were positive. Of the remaining women, 83.2% (129/155) received a test at the time of delivery, of whom 5.4% (7/129) were positive. Overall prevalence of HBsAg positivity was 2.8% (21/755).Conclusions
Further studies are urgently needed to establish the prevalence of HBV infection in Timor-Leste, particularly in pregnant women. Findings from this study suggest that routine HBV immunisation of newborns should be instituted promptly.
