Prevalence and genotype distribution of human papillomavirus in women in the Henan Province
We studied human papillomavirus (HPV) prevalence and genotype distribution among women in the Henan Province to provide epidemiological data as a means of preventing cervical cancer and developing a vaccine. A total of 14,873 samples were genotyped by using polymerase chain reaction reverse dot-blot. The overall HPV-positive rate in the sample was 23.98% (3566/14873), of which 69.01% (2461/3566) were infected with high-risk HPV types and 17.33% (618/3566) with low-risk types.
