Distribution patterns of human papillomavirus genotypes among women in Guangzhou, China

Abstract

Abstract Background Cervical cancer is associated with high‐risk human papillomavirus (HR-HPV) infection in the world. We aimed to evaluate the status of HPV infection among women in Guangzhou, China. Methods The study recruited 28,643 female patients from the Guangzhou Women and Children’s Medical Center for HPV genotype testing between 2019 and 2021. Results 5668 patients were infected with HPV, resulting in an overall infection prevalence of 19.78%. The prevalence of HR-HPV was recorded at 13.94% (both single-infections and multi-infections), probably high-risk HPV/possibly carcinogenic (pHR-HPV) as 3.51%; and low-risk HPV (LR-HPV) as 3.56%. The most common HR-HPV genotype detected was HPV-52 with an infection rate of 4.99%, followed by HPV 58 (2.18%), 16 (2.12%), 51 (1.61%), 39 (1.19%), 56 (1.09%), 59 (0.85%), 18 (0.72%), 33 (0.61%), 31 (0.53%), 35 (0.20%), 45 (0.17%). Among LR-HPV genotypes, HPV-42 was the most common (1.08%), followed by 44 (0.77%), 81 (0.68%), 6 (0.48%), 43 (0.40%), 11 (0.23%) and 83 (0.07%). The prevalence of infection among different genotypes in pHR-HPV was: 68 (1.29%), 53 (1.21%), 66 (0.77%), 82 (0.25%), 73 (0.16%). Additionally, the prevalence of single genotype HPV infection exceeded that of multiple HPV infections except HPV-59. Conclusion Our findings imply that HPV genotype infections in Guangzhou demonstrate a regional and age-related distribution. Therefore, these data can provide a substantial foundation for further epidemiologic analysis to control and prevent HPV infections in Guangzhou.
