In this study, a total of 301 880 women were recruited from four different regions of Western China, with 301 880 exfoliated cervical cell samples collected from women for DNA isolation and purification. The HPV genotype was tested by polymerase chain reaction. The overall HPV prevalence rate, high-risk (HR) HPV infection rate, low-risk (LR) HPV infection rate and mixed HPV infection rate was 18.24%, 79.14%, 12.56% and 8.30%, respectively. The four most common HR HPV subtypes were HPV-52, 16, 58 and 53, which accounted for 20.49%, 19.93%, 14.54% and 10.01%, respectively. In LR HPV genotype, HPV-6 ranked the highest (28.17%), followed by HPV-81 (9.09%) and HPV-11 (3.78%). HPV genotype subgroup analysis also showed that single-type infection was the most common (77.26%) among HPV-positive individuals. Among multi-infection genotypes, double infection was the most common with frequencies of 76.04%. The overall prevalence of HPV is high in Western China, whose distribution demonstrates different patterns across different ages and regions. Viral genotypes HPV 53, 6 were frequently detected in this population, which is worth of significant clinical attention.<\/jats:p>","DOI":"10.1017\/s0950268821001175","type":"journal-article","created":{"date-parts":[[2021,5,18]],"date-time":"2021-05-18T06:40:46Z","timestamp":1621320046000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":16,"title":["The genomic distribution map of human papillomavirus in Western China"],"prefix":"10.1017","volume":"149","author":[{"given":"Ling","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yan","family":"Dong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiao","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinqiu","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huandong","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jungao","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zuoyi","family":"Yao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5533-7995","authenticated-orcid":false,"given":"Xiaosong","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2021,5,18]]},"reference":[{"key":"S0950268821001175_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(07)70158-5"},{"key":"S0950268821001175_ref11","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.20244"},{"key":"S0950268821001175_ref12","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(09)70096-8"},{"key":"S0950268821001175_ref10","doi-asserted-by":"publisher","DOI":"10.1155\/2019\/3257939"},{"key":"S0950268821001175_ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcv.2004.12.008"},{"key":"S0950268821001175_ref15","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(13)60022-7"},{"key":"S0950268821001175_ref16","first-page":"265","article-title":"Immunogenicity and safety of human papillomavirus (HPV) vaccination in Asian populations from six countries: a meta-analysis","volume":"47","author":"Setiawan","year":"2017","journal-title":"Japanese Journal of Clinical Oncology"},{"key":"S0950268821001175_ref24","doi-asserted-by":"publisher","DOI":"10.3390\/ijms18020366"},{"key":"S0950268821001175_ref30","doi-asserted-by":"publisher","DOI":"10.21037\/atm.2016.05.49"},{"key":"S0950268821001175_ref31","doi-asserted-by":"publisher","DOI":"10.1002\/jmv.21826"},{"key":"S0950268821001175_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/S2214-109X(19)30482-6"},{"key":"S0950268821001175_ref28","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-018-3105-x"},{"key":"S0950268821001175_ref20","doi-asserted-by":"publisher","DOI":"10.1186\/s12985-019-1239-0"},{"key":"S0950268821001175_ref32","doi-asserted-by":"publisher","DOI":"10.1016\/j.cca.2012.11.005"},{"key":"S0950268821001175_ref22","doi-asserted-by":"publisher","DOI":"10.7150\/jca.14971"},{"key":"S0950268821001175_ref8","doi-asserted-by":"publisher","DOI":"10.3390\/ijms19092619"},{"key":"S0950268821001175_ref19","doi-asserted-by":"publisher","DOI":"10.1186\/s12985-017-0751-3"},{"key":"S0950268821001175_ref18","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-015-0998-5"},{"key":"S0950268821001175_ref26","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0210311"},{"key":"S0950268821001175_ref21","doi-asserted-by":"publisher","DOI":"10.1038\/srep21039"},{"key":"S0950268821001175_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2012.07.055"},{"key":"S0950268821001175_ref6","first-page":"87","article-title":"Global cancer statistics, 2012","volume":"65","author":"Torre","year":"2015","journal-title":"CA: A Cancer Journal for Clinicians"},{"key":"S0950268821001175_ref25","doi-asserted-by":"publisher","DOI":"10.1002\/path.4405"},{"key":"S0950268821001175_ref13","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.30716"},{"key":"S0950268821001175_ref3","first-page":"D1","article-title":"Human papillomavirus (HPV) and related cancers in the Global Alliance for Vaccines and Immunization (GAVI) countries.
