Hepatitis B chronic infection among pregnant women attending the antenatal care in Bor State Referral Hospital, South Sudan
Abstract
Introduction: Hepatitis B virus (HBV) is a major public health problem affecting 400 million people worldwide, and is a common cause of chronic liver failure (cirrhosis) and hepatocellular carcinoma. Sixty-eight percent of infected people are from the African and Pacific regions. Vertical transmission from mother to newborn baby is one of the mechanisms by which chronic hepatitis virus infection spreads, besides infections from contaminated needles and syringes and sexual contact. Hepatitis B chronic infection is endemic in many poor countries, especially in Africa. Method: A cross-sectional study was conducted between July and August 2021. Pregnant women attending the antenatal care (ANC) in Bor State referral hospital, South Sudan, were interviewed to collect information on their socio-demographic characteristics and risk factors for hepatitis B infection. The objective was to determine the seroprevalence of hepatitis B chronic infection through blood testing. Prevalence ratios for certain risk factors were calculated. Results: Two hundred pregnant women were enrolled. The Prevalence Rate for chronic infection with hepatitis B virus, diagnosed using the rapid immune-chromatographic assay for Hepatitis B surface antigen (HBsAg), was 8.5%. (95% CI; 4.7% - 12.3%). None of the suspected risk factors studied were found to be significantly associated with testing positive for HBV, except for a history of previous jaundice. Conclusion: The prevalence of HBV chronic infection among pregnant women in Bor, Jonglei State, is high; hence, there is a need for established public health interventions that can lead to a reduction of HBV vertical transmission. Treatment of pregnant women with HBV chronic infection using anti-viral medications during pregnancy might curb the vertical transmission rates.
