Why does HPV recur after it turns negative?

HPV infection may occur throughout a woman's life. If high-risk HPV infection persists, it may cause cervical epithelium to show lesions or even cancer. This situation should be given high attention. about 80% of patients are infected with high-risk HPV. After a year or so, they will turn negative on their own, but infection may occur again after turning negative. Therefore, it is very important for women to do regular screening for cervical cancer. It is recommended to do screening once a year and deal with it in time after finding abnormalities.
