“…Hepatitis B core antibodies were present in more than 65% of the study subjects, similar to that observed in the general population of West Africa [Zanchetta et al, 1990;Roingeard et al, 1993;Diallo et al, 1995;Combe et al, 2001]. HBsAg prevalence rates at both study sites were higher than the 9.3% reported recently among pregnant women in Ouagadougou (Simpore et al, 2004a), but are close to the previously described rates of 17.4%-21.3% in Burkina Faso [Nacro et al, 2001;Mulders et al, 2004].…”

A seroprevalence study was carried out of six different human pathogenic viruses, namely human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), human T-cell leukemia virus (HTLV), human herpesvirus type 8 (HHV-8), and dengue virus among pregnant women and blood donors from rural (Nouna) and urban (Ouagadougou) Burkina Faso, West Africa. A total of 683 samples from blood donors (n = 191) and pregnant women (n = 492) were collected from both sites and screened for the different virus infection markers resulting in the following prevalence values for Nouna or Ouagadougou, respectively: HIV 3.6/4.6, anti-HBV core (anti-HBc) 69.6/76.4, HBV surface antigen (HBsAg)14.3/17.3, HCV 2.2/1.5, HTLV 1.4/0.5, HHV-8 11.5/13.5, dengue virus 26.3/36.5. Individuals aged > or =25 years were more likely to be infected with HIV than those below 24 years (P < 0.05). Infection with HIV increased the likelihood of co-infection with other viruses, such as HHV-8, HBV and HTLV. Co-infection studies involving five viruses (HBV-HBsAg, HHV-8, HIV, HCV, and HTLV) showed that 4.8% (33/683) of the studied population were dually infected, with HBsAg+ HHV-8 (13/33), HBsAg+HIV (8/33) and HIV+HHV-8 (8/33) being the most common co-infections. Of the population studied 0.6% (4/683) was triply infected, the most common infection being with HBV+HIV+HHV-8 (3/4). There was no difference in the prevalence of HIV, anti-HBc, HBsAg, HCV, HTLV, and HHV-8 either among blood donors or pregnant women in urban or rural setting, while dengue virus prevalence was relatively lower in rural (26.3%) than in urban (36.5%) Burkina Faso.

“…In other studies elsewhere in Africa, prevalence varied from 0-50% was reported without any clear explanation on these variations [12][13][14]. In two previous studies carried out in the northern part of Benin, Zanchetta et al [7] reported 19.4% prevalence rate for anti-HDV antibodies while a rate of 11.4% was reported by de Paschale et al some years later [8]. These findings were higher than what was found in the present study.…”

“…In Benin, data on co-infection with HDV, HCV and HIV in HBV infected patients are rare. To our knowledge, the only two published studies on co-infection with these viruses were on a limited number of patients in one hospital in the Northern part of the country [7,8]. We aimed in the present study to assess the prevalence of HDV, HCV and HIV infections in patients chronically infected with HBV in Cotonou, the largest city in Benin.…”

Infections with hepatitis viruses are known to be prevalent in sub-Saharan Africa but in Benin, data on these infections are still scarce. The study was carried out to assess the burden of these infections in Cotonou. From June to October 2016, we conducted a cross-sectional study on 156 Hepatitis B Virus (HBV) infected patients attending the University Teaching Hospital and a private hospital in Cotonou. For each patient, HBV viral load measurement and Hepatitis Delta Virus (HDV), Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV) serology tests were performed using standard methods. The median HBV viral load was 557.5 UI/mL and HDV, HCV and HIV sero-prevalence rates were 3.9%, 1.3% and 0.7% respectively. In conclusion, in HBV infected patients in Cotonou, the sero-prevalence rates of HDV, HCV and HIV were relatively low. A national prevalence survey is needed to assess the epidemiology of these infections in the country.

Introduction: The epidemiology of viral hepatitis during pregnancy is of paramount importance for health planners and program managers. Data on viral hepatitis during pregnancy are not readily available in many African and Arab countries. Both regions have their own unique geography, and comprise over 59 states with crossover and interaction of different cultures. Methodology: A systematic electronic search of the published literature was conducted and data on epidemiology and risk factors of maternal hepatitis B virus (HBV) infection and hepatitis C (HCV) infection in Arab and African countries were extracted from relevant studies. Results: The serology of hepatitis viruses varies greatly among these countries, with different viral genotype patterns. Such a variation in prevalence could be explained by the different risk factors involved. Sexual contact, perinatal infection, blood and its derivatives, hemodialysis, intravenous and percutaneous drug use, and occupational, habitual, and social behavior have been identified as risk factors for hepatitis transmission in various settings in these countries. Conclusions: Infection from hepatitis B and C viruses imposes major socioeconomic and even political burdens on such young and dynamic societies. Thus strategies and clear policies of intervention are required to combat the consequences of hepatitis B and C at both the regional and national levels.
