OBJECTIVE To determine the seroprevalence of antibodies to hepatitis B virus (HBV) and hepatitis A virus (HAV) among children in Jeddah, Kingdom of Saudi Arabia (KSA) and to evaluate the need of anti-HAV mass vaccination. METHODS This study was carried out on random samples of schools located at different regions in Jeddah, KSA during the year 2004. A total of 527 sera, (285 males and 242 fem...

BACKGROUND Published data on HIV, HBV, and HCV in correctional facilities in Nigeria is scarce. We set out to establish the seroprevalence, co-infection, and risk factors for these infections for the first time among prison inmates in Nasarawa State, Nigeria. METHODOLOGY In a cross-sectional study conducted between April and May, 2007, blood samples were collected from 300 male prisoners of a...

BACKGROUND AND OBJECTIVE Several reports indicated a declining trend in the occurrence of hepatitis D virus (HDV) infection in some geographical areas. However, no study has been conducted in India to evaluate whether a similar epidemiological change is occurring in this part of the world. The present study was undertaken to evaluate the seroprevalence of HDV in patients with hepatitis B virus ...

OBJECTIVE There are a limited number of studies on the seroprevalence of Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infection in Turkey. This study aimed to compare HBV and HCV seroprevalence rates before and after the implementation of national hepatitis B vaccination program (NHPVP) and to explore age-related changes in the seroprevalences. MATERIALS AND METHODS Results of Hepatiti...

BACKGROUND Persons with chronic hepatitis B (CHB) infection were reported to suffer severe disease after hepatitis E virus (HEV) superinfection, but the studies regarding HEV seroprevalence in this population were limited. A recent study in Vietnam found higher HEV seroprevalence among CHB patients compared with healthy controls. METHODS A community-based case-control study was conducted in t...

INTRODUCTION In this study, we aimed to compare the HBV seroprevalances of voluntary blood donors and the healthy persons who required premarital screening. METHODOLOGY HBsAg ELISA results were collected retrospectively from the records of 9,949 blood donors and 954 healthy persons who required premarital screening. RESULTS HBsAg was detected in 182 of 9,949 (%1.8) voluntary blood donors an...

INTRODUCTION Human T-lymphotropic virus types 1/2 (HTLV-1/2) are distributed worldwide and are endemic in specific regions. METHODS Serological evaluation of the HTLV-1/2 prevalence and co-infection rate [human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), Chagas disease, and syphilis)] for 2011-2014 was performed with volunteer blood donors from the western ...

BACKGROUND Infection with the hepatitis B virus (HBV) is an important global health problem. Knowledge of the geographic distribution pattern of HBV infection can help to control the spread of the disease. OBJECTIVES To determine the prevalence of HBV infections and risk factors for the disease for the first time in Birjand, Southeastern Iran. METHODS This was an analytical cross-sectional ...

Few studies are available on hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) co-infection in populations living in small and medium-sized Brazilian cities. We evaluated the seroprevalence of these viruses in selected individuals from a clinic of infectology, who were referred to the University Regional Hospital of the West Region of state of São Paulo, Br...
