Prevalence and genotype distribution of human papillomavirus in 92,932 cases in Shanghai, China

Abstract

Aim: Human papillomavirus (HPV) is the most common cause of high-grade lesions and carcinogenesis such as cervical intraepithelial neoplasia (CIN) and cervical cancer (CC). The prevalence and genotype distribution of HPV infection varies greatly in different geographical areas. Patients & methods: This study enrolled 92,932 patients from January 2017 to December 2021 and analyzed the prevalence and distribution of HPV genotypes. Results: 18038 (19.41%) specimens were HPV-positive. No significant difference in infection rates between men and women (19.05 vs 19.41%). The most prevalent HPV subtypes are HPV52, HPV58, HPV16, HPV53, HPV51 and HPV81. Single infection of HPV has dominated in HPV-positive patients. Conclusion: Our results show that the prevalence and distribution of HPV subtypes have obvious region-specific and age-specific characteristics.
