Symptoms of HPV conversion are determined by the type of HPV infection, with high-risk types usually showing no obvious signs of conversion, while low-risk types no longer produce fresh lesions and the itching improves.
Because high-risk HPV infections do not cause significant discomfort, there are no obvious signs that the disease has turned negative.
If the low-risk type of HPV infection after regular treatment, no new warts appear, and the itching and other symptoms of discomfort effectively improved, generally indicates that the HPV infection has been controlled, and may gradually turn negative.
