OBJECTIVES The prevalence of HPV infection and HPV genotypes varies in different regions. However, there is little data on HPV prevalence and genotyping in Guangxi Province, south China. This study conducted a ten-year survey in a health center, to estimate the prevalence characteristics of HPV genotypes. METHODS By using polymerase chain reaction (PCR) amplification and nucleic acid molecular hybridization, the HPV genotypes were detected from 77,756 females who were patients of the Department of Obstetrics and Gynecology and those who visited the Health Management Center for a physical examination between August 2011 and November 2020. The prevalence, genotypes, age-related HPV infections, as well as chronological change of HPV prevalence and the HPV genotype distribution were analyzed. RESULTS The overall prevalence of HPV infection was 21.14% (16,439/77,756). The HPV infection rate differed significantly between the patients of the Department of Obstetrics and Gynecology and the women who underwent a physical examination (22.98% versus 9.88%, p < 0.05). The prevalence rates of high-risk HPV, low-risk HPV, mixed HPV (mixed high-risk, and low-risk HPV infection), and multiple HPV infections were 18.96% (14,739/77,756), 4.09% (3,178/77,756), 1.90% (1,478/77,756), and 4.94% (3,838/77,756), respectively. The most prevalent genotypes were HPV 52, 16, and 58. The age-associated HPV prevalence showed bimodal curves, with the first peak at <25 years and the second peak at >56 years. CONCLUSIONS This study provides baseline data on the HPV prevalence in the general female population of Nanning, Guangxi Province. Women <25 and >56 years old faced the greatest threat of HPV infection, and HPV 52, 16, and 58 were the most common genotypes. This article is protected by copyright. All rights reserved.
