How long does HPV infection cause low-grade lesions?

HPV infection generally causes low-grade lesions in 2-3 years.

If the tissue metabolism is slow, the immune system function is abnormal, which helps HPV virus to replicate in large quantities in the body, it may cause long-term stimulation to local tissues. At this time, it takes a relatively short time to cause low-grade lesions, usually about 2 years. If the basal metabolic rate of the body is fast and the immune system function is normal, it is not conducive to providing the environment required for HPV virus replication in vivo, which is beneficial to slowing down HPV virus replication. At this time, the time required for low-grade lesions to occur is prolonged, usually about 3 years.
