The first universal hepatitis B vaccination program for newborns in the world was launched in Taiwan in July 1984. Most studies on the effectiveness of hepatitis B vaccination focused on the seroprevalence of HBs Ag among children under 14 years old. Only few studies focused on the seropositivity of anti-HBs among adolescents aged 15-18 years old. The present study aimed to evaluate the impact ...
Background: The seroprevalence of human parvovirus-4 (PARV4) varies considerably by region. In sub-Saharan Africa, seroprevalence is high in the general population, but little is known about the transmission routes or the prevalence of coinfection with blood-borne viruses, HBV, HCV and HIV. Methods: To further explore the characteristics of PARV4 in this setting, with a particular focus on the...
OBJECTIVE To determine the seroprevalence of markers of transfusion transmissible infections in donors of a blood bank in Medellin, Colombia, beteween 2007 and 2010. METHODS A cross-sectional secondary data source, based on the results of biological testing of donors to a blood bank in Medellin. We determined the seroprevalence of markers of infection and were compared by sex and type of dono...
Background Serological screening of blood donors provides data on seroprevalence of certain infections among apparently healthy people of working age population belonging to a particular geographic area. The study’s objectives pursued the prevalence of infection with hepatitis B (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV) and Treponema pallidum on a sample population of D...
A seroprevalence study was carried out among a group of women in Rio de Janeiro to determine the prevalence of different markers for viral hepatitis given the limited data among healthy populations. Blood samples collected and tested from 874 women before or after delivery in a public county maternity hospital demonstrated age to be directly related to markers for hepatitis A virus and hepatiti...
Introduction To estimating the seroprevalence of HIV, hepatitis B, hepatitis C and syphilis among blood donors in the Aïoun hospital. Methods This is a retrospective study from 1 January 2010 to 31 December 2015. Results On the five-year study period, 1,123 donors were collected. Of these, 182 were HIV-positive, an overall prevalence of 16.2% with predominance in male with a sex ratio Man/W...
Introduction: There is variability of data regarding seroprevalence and coinfection of hepatitis viruses. Our objective was to determine the magnitude, pattern and coinfection of hepatitis viruses in clinically suspected cases of acute infectious hepatitis. Methods: This descriptive study was conducted in the Department of Microbiology at Lady Hardinge Medical College, New Delhi, over a period ...
BACKGROUND Few studies exist on hospital-based seroprevalence of triple positivity of HIV/HBV/HCV in Nigeria. OBJECTIVES The study aimed at determining the triple positivity of HIV, HBsAg and HCV among HIV-infected individuals in Abeokuta, Nigeria and defining the influence of these triple infections on CD4+ counts of HIV-infected individuals as antiretroviral therapy improves in Nigeria. M...
