Abstract

Human papillomavirus (HPV) infection plays a key role in the development of cervical cancer. The aim of the current study was to investigate the HPV type distribution in Chinese women from Yunnan Province, southwest China. A total of 28,457 individuals ranging in age from 17-84 years were recruited from 13 clinical hospitals located in 10 different regions of Yunnan Province. Cervicovaginal swabs were collected from each participant, and HPV screening was performed using Luminex xMAP technology. Our results showed that the HPV prevalence was 12.9% in Yunnan Province. Overall, 10.6% of the individuals were positive for a single HPV type, and 2.3% were positive for multiple types. Among the individuals who tested positive for a single HPV type and multiple HPV types, the three most prevalent high-risk types were 52, 16, and 58. Age subgroup analysis showed two peaks for the frequencies of single and multiple HPV infections, one for the group of women under 25 years old, and the other for the group over 56 years old. Here, we present data regarding the prevalence and type distribution of HPV infection, which will aid in the estimation of the potential clinical benefit and cost-effectiveness of HPV screening and vaccination in China.
