Seroprevalence of Hepatitis B Virus in Rural and Urban Areas in Togo

Abstract

Infection with the hepatitis B virus (HBV) is a public health problem in many parts of the world, due to its frequency, complications and socio-economic consequences. This study aimed to assess the seroprevalence of hepatitis B virus infection in rural areas and in urban areas. This cross-sectional study assessed the prevalence of HBV infection from 2015-2018 at CHR-Sokodé and USP of Ogaro. Biological data of 3000 participants (500 per year in each zone) enrolled and results of HBsAg were assessed during the study period. Female are represented 60% with average age comprised between [20, 29] years old. The high rate of participants enrolled (45.10%) are come for the monitoring of pregnancy. The prevalence of VHB during the study are 20.33% (610/3000), high prevalence (6.27%) and the means of VHB prevalence are shown in the age range between [30; 39] with 12.17% (365/3000) of female and 8.17% (235/3000) of male are positive after diagnostic detection of HBsAg (antigen of Hepatitis B virus). The prevalence of HBV in rural zone (Ogaro) are 5.23% and 15.07% in urban zone (Sokodé) and the high prevalence (17.50%) are shown in urban zone. The high prevalence of young suggests that some effort will be due to sensibilized young for HBV sexual transmission and the way of prevention. In addition, some research would be done in research of alternative therapy against this infection.
