We aimed to determine the seroprevalence of hepatitis infection and dual or triple hepatitis infections among 10\u201364-year-olds. A questionnaire was used to identify risk factors for hepatitis infection, and seromarkers were measured by the fully automated immunologic analyzer HISCL-5000. Among a total of 10,040 participants, 8.1% of the population aged 10\u201364 was infected with HBV, 9.4% with HCV, and 0.4% with HBV and HCV, and the prevalence of the disease varied by age, sex, and the area of residence. Young people were particularly unaware of their hepatitis infection status. A small proportion of children aged 10 to 19 years and the majority of adults younger than 30 years were unaware of their HBV and HCV infection. Men were also more likely to be unaware of their HBV and HCV infection status than women. The results suggested that the prevalence of infection in the general population is high and that most people are unaware that they are infected or have become chronic carriers. Identifying mono-, co-, or triple-infection status is critical to prevent the rapid progression of liver disease among the Mongolian population.<\/jats:p>","DOI":"10.3390\/vaccines10111928","type":"journal-article","created":{"date-parts":[[2022,11,15]],"date-time":"2022-11-15T02:28:58Z","timestamp":1668479338000},"page":"1928","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Hepatitis B, C, and D Virus Infection among Population Aged 10\u201364 Years in Mongolia: Baseline Survey Data of a Nationwide Cancer Cohort Study"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6999-9367","authenticated-orcid":false,"given":"Davaalkham","family":"Dambadarjaa","sequence":"first","affiliation":[{"name":"School of Public Health, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Otgonbayar","family":"Radnaa","sequence":"additional","affiliation":[{"name":"School of Medicine, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ser-Od","family":"Khuyag","sequence":"additional","affiliation":[{"name":"School of Public Health, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oyu-Erdene","family":"Shagdarsuren","sequence":"additional","affiliation":[{"name":"School of Public Health, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uranbaigali","family":"Enkhbayar","sequence":"additional","affiliation":[{"name":"School of Medicine, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yerkyebulan","family":"Mukhtar","sequence":"additional","affiliation":[{"name":"School of Public Health, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enkh-Oyun","family":"Tsogzolbaatar","sequence":"additional","affiliation":[{"name":"School of Public Health, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9752-4350","authenticated-orcid":false,"given":"Gunchmaa","family":"Nyam","sequence":"additional","affiliation":[{"name":"School of Public Health, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shatar","family":"Shaarii","sequence":"additional","affiliation":[{"name":"School of Public Health, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9820-2887","authenticated-orcid":false,"given":"Pramil","family":"Singh","sequence":"additional","affiliation":[{"name":"Transdisciplinary Tobacco Research Program, Loma Linda University Cancer Center, Loma Linda, CA 92354, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaharu","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Division of Virology, Department of Infection and Immunity, Jichi Medical University School of Medicine, Shimotsuke 329-0498, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bira","family":"Namdag","sequence":"additional","affiliation":[{"name":"School of Medicine, Mongolian National University of Medical Sciences, Ulaanbaatar 14210, Mongolia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0827-0964","authenticated-orcid":false,"given":"Hiroaki","family":"Okamoto","sequence":"additional","affiliation":[{"name":"Division of Virology, Department of Infection and Immunity, Jichi Medical University School of Medicine, Shimotsuke 329-0498, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"20160274","DOI":"10.1098\/rstb.2016.0274","article-title":"Viral Hepatitis and Liver Cancer","volume":"372","author":"Ringelhan","year":"2017","journal-title":"Philos.
