There were 79 patients in the low-grade squamous intraepithelial lesion (LSIL) group, and 202 patients in the high-grade squamous intraepithelial lesion (HSIL) group. The proportion of 30– 45 years old in HSIL group was 58%. Overall, single infections accounted for 76%, and HR-HPV infections accounted for 90.1%. The most common HR-HPV subtypes in the two CIN groups were almost the same, including HPV16, HPV58 and HPV52. The most common LR-HPV subtype in the two CIN groups was HPV43. There were no significant differences in ethnic and single or multiple infection rates among different CIN groups. Single infection of HPV43 and HPV81 was found in minority HSIL patients.Conclusion: HPV infection in Yunnan was dominated by single infection and HR-HPV. Patients aged 30 to 45 years were in the high incidence of HSIL, and the most common HR-HPV subtypes were HPV16, HPV58, and HPV52. Single LR-HPV infection exists in minority HSIL patients.Keywords: human papillomavirus, cervical intraepithelial neoplasia, low-grade cervical intraepithelial neoplasia, high-grade cervical intraepithelial neoplasia |
