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

The body’s immune system is remarkably effective at clearing human papillomavirus (HPV) infections. Research indicates that approximately 70% of HPV infections are resolved by the body within two years without progressing to higher-grade lesions such as cervical intraepithelial neoplasia grades 2 or 3 (CIN2 or CIN3). This clearance rate reflects the effectiveness of the immune response in managing and eliminating transient HPV infections, which are common and often asymptomatic.

It's important to note that the remaining infections may not clear and can lead to more severe changes in cervical cells, but the majority do resolve, emphasizing the crucial role of immune surveillance in controlling HPV and reducing the risk of developing cervical cancer.
