| impact of routine hepatitis b immunization on the prevalence of chronic hepatitis b virus infection in the marshall islands and the federated states of micronesia. | to evaluate the impact of routine hepatitis b (hb) vaccination on the prevalence of chronic hepatitis b virus (hbv) infection among children in pacific island countries where hbv infection was highly endemic, we conducted hb serosurveys during 2000 to 2007 among women of childbearing age born before implementation of hb vaccination and among children born after its implementation. | 2010 | 19841605 |
| htlv-1, hiv-1, hepatitis b and hepatitis delta in the pacific and south-east asia: a serological survey. | blood samples from 13 locations in the pacific and south-east asia were tested for evidence of infection with human t-cell lymphotropic virus type-1 (htlv-1), human immunodeficiency virus (hiv-1), hepatitis b virus (hbv) and hepatitis delta virus (hdv). no samples were positive for antibody to hiv-1. antibodies to htlv-1 were found in samples from five locations, the maximum prevalence being 19%, in vanuatu. serological markers of hbv infection were found in all locations, the maximal prevalence ... | 1988 | 2892692 |
| studies on hepatitis b surface antigen and antibody in nauru. i. distribution amongst nauruans. | the age specific prevalence of hepatitis b surface antigen and antibody was studied among a random sample of nauruans over the age of 10 years. overall, 79% of subjects showed evidence of past infection with hepatitis b virus with the highest prevalence among young people. while there was no difference in the infection rate between males and females, the carrier rate in males was 50% higher. in both sexes the carrier rate declined with increasing age. significant differences in carrier rates wer ... | 1978 | 717627 |
| prevalence of antibody to hepatitis a and hepatitis b viruses in selected populations of the south pacific. | five island populations representing the three major cultural groups of the south pacific--polynesia, micronesia, melanesia--were studied for prevalence of antibody to hepatitis a virus (anti-hav) and of antibody to the core antigen of hepatitis b virus (anti-hbc). sera were collected in the late 1950s and early 1960s, selected where possible for appropriate age and sex distributions, and were tested by radioimmunoassay. rather marked differences in prevalence were observed. anti-hbc patterns co ... | 1979 | 224696 |
| hepatitis b surface antigen screening among pregnant women and care of infants of hepatitis b surface antigen-positive mothers - guam, 2014. | hepatitis b virus (hbv) infection is endemic among adults in the u.s. territory of guam (1,2). perinatal hbv transmission, which occurs at birth from an infected mother to her newborn infant, is a major mode of hbv transmission and maintains hbv endemicity (3). approximately 90% of hbv-infected infants will develop chronic hbv infection, and approximately 25% of those will die prematurely from liver failure or hepatocellular carcinoma (4,5). since 1988, the advisory committee on immunization pra ... | 2017 | 28520708 |
| improving hepatitis b birth dose coverage through village health volunteer training and pregnant women education. | hepatitis b is highly endemic in the republic of kiribati, while the coverage of timely birth dose vaccination, the primary method shown to prevent mother-to-child transmission of hepatitis b virus, was only 66% in 2014. children born at home are especially at high risk, as they have limited access to timely birth dose (i.e. within 24 h) vaccination. to improve birth dose coverage, a project to improve linkages between village health volunteers and health workers and educate pregnant women on he ... | 2017 | 28688784 |
| progress towards achieving hepatitis b control in the cook islands, niue, tokelau, and kiribati. | hepatitis b virus (hbv) is highly endemic in many of the pacific island countries. four island countries-cook islands, kiribati, niue, and tokelau-sought to evaluate the success of their hepatitis b vaccination programs by conducting nationally representative serosurveys among children born post-vaccine introduction. | 2016 | 27402565 |
