The retrospective study showed a high prevalence of HPV infection in Chaohu City in the past two years. More high-risk genotype infection and single infection than low-risk genotype infection and multiple infection, and high-risk genotype infection and single infection mainly occurring in the middle and old age were the characteristics of HPV infection in Chaohu. HPV 52, 53, and 58 were the dominant HPV genotypes, suggesting that vaccine which contained HPV 52, 53, and 58 genotypes might be a better choice for this region.
