Objective: To investigate the epidemiological characteristics and genotypes of human papillomavirus (HPV) infection in Mianyang. Methods: The cervical samples of 27,040 patients, who visited the Department of Gynecology of The Third Hospital of Mianyang from January 2018 to January 2020, were collected. Results: The HPV-positive infection rate was 21.40% (5,787/27,040); the single HPV infection rate was 72.04% (4,169/5,787); the double HPV infection rate was 19.73% (1,142/5,787); the triple and above HPV infection rate was 8.22% (476/5,787); the top five high-risk HPV subtypes with the highest infection rates were HPV52, 16, 58, 53, and 51, while the top five low-risk HPV subtypes with the highest infection rates were HPV81, 42, 43, 6, and 11; there were significant differences in the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate among different age groups (P < 0.05). Conclusion: The HPV infection rate in Mianyang was 21.4%, in which the majority of the cases were single infection; the high-risk HPV subtypes were HPV52, 16, 58, 53, and 51; the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate were high in the middle but low at both ends in the context of age distribution; the top three age groups with the highest infection rates were 45-49, 40-44, and 30-34.
