A total of 1535 randomly collected blood specimens from different groups of consenting subjects in Benue State, were screened by ELISA for Hepatitis B surface antigen (HBsAg), hepatitis B surface antibodies (HBsAb), hepatitis B core antibodies (HBcAb), hepatitis Be antigen (HBeAg) and Hepatitis B core IgM antibodies (HBcIgM). The pattern of occurrence of these HBV markers in each blood sample was used to determine individuals with current, acute or chronic infection histories. Of the 1535 sampled individuals, 1319 (85.9%) showed a serological evidence of exposure to HBV infection, some through natural infection (22.7%) and others (13.0%) through vaccination; 12% of the exposed were inferred to be currently infected and 91.2% chronically infected. Hepatitis delta virus (HDV) antigen was also detected in 2.7% of the HBsAg positive individuals; and was encountered more (6.7%) in those with acute hepatitis than those with chronic disease. Thus, there are apparently healthy persons with acute and chronic HBV and HDV infection who may serve as source of infection to others. This calls for a government organized Hepatitis Programme to treat cases of acute and chronic hepatitis and roll out strategy for preventing the spread of HBV infections.

Background: Sexually Transmitted Infections (STIs) have been shown to enhance the transmission of the Human Immunodeficiency Virus (HIV). The Hepatitis B and the Hepatitis C viral infections are highly prevalent among the HIV-infected persons as a result of shared transmission routes. Aim:To determine the seroprevalence of the HIV, Syphilis, HBV and HCV infections and their co-infection rates among Female Sex Workers (FSWs). Settings and Design: 250 blood samples were collected from FSWs from a red light area of Mumbai by using an outreach strategy. Materials and Methods:Their sera were tested for the HIV antibodies as per the strategy II of the NACO guidelines, for syphilis by RPR, for the HCV antibodies and for HBsAg by ELISA.

“…In contrast, there are several prevalence studies in many settings on hepatitis B in Nigeria. [2][3][4][5][6] In addition, this paper utilizes results of HBVDNA in determining HB status. 18 Over 40% of the children had been exposed to the HB virus and 12% were positive for the HB surface antigen.…”

“…1 The infection is hyper-endemic in Nigeria with prevalence rates of the HB surface antigen (HBsAg) varying in different segments of the population. [2][3][4][5][6] The HBsAg prevalence rate was 11% amongst pregnant women, 2 17% in female sex workers 3 and 15% in a low-risk blood donor group. 4 In children, without the human immunodeficiency virus (HIV), the HBsAg prevalence was 9% 5,6 and 19% in those who had HIV.…”
