What percentage of HPV infections are cleared by the body and do not develop to CIN2 or CIN3?

Research has shown that a significant percentage of human papillomavirus (HPV) infections are spontaneously cleared by the body's immune system without causing any long-term effects. Specifically, studies indicate that about 70% of HPV infections are resolved naturally within two years. This high clearance rate is one of the reasons why many individuals with HPV do not progress to precancerous lesions such as cervical intraepithelial neoplasia (CIN) grades 2 and 3. Understanding the body’s ability to clear HPV is crucial for assessing risk and developing preventive strategies, including vaccination and routine screening.
