Prevalence and genotype distribution of human papillomavirus among females in the suburb of Shanghai, China.

To describe the prevalence of human papillomavirus (HPV) and its genotype distribution among females in the suburb of Shanghai. A total of 33 562 participants were enrolled in this study from January to December 2016. HPV GenoArray test kit was used to perform HPV genotyping and was also used in DNA amplification and HybriBio's proprietary flow-through hybridization technique. The overall prevalence of HPV was 18.98% and the top ten genotypes of HPV infection were HPV 16 (3.36%), HPV 58 (2.65%), HPV 52 (2.48%), HPV 51 (1.58%), HPV 54 (1.40%), HPV 68 (1.32%), HPV 18 (1.23%), HPV 6 (1.15%), HPV 56 (1.10%), and HPV 33 (1.07%). Single infection (4749, 14.15%) was the most common types among all the infected cases. Significant differences were found among age groups and month groups in terms of simple and multiple infection (P < 0.05), pure HR, LR and mixed HPV infection (P < 0.05). The prevalence of HR and LR HPV infection among females in the suburb of Shanghai is high, prevalence of single and multiple infection, pure HR, LR and mixed infection is correlated with the age and month.
