There is a possibility of re-infection after HPV conversion. There are two scenarios for HPV conversion, one is that the virus has been completely eliminated, and the other is that the virus has a low level of replication, which cannot be detected by the current testing methods. Therefore, for patients with a low level of replication of the virus, when the body’s resistance becomes low, it is possible that the virus may multiply, and then it may be re-infected to other people. For HPV-negative women, it is important to note that there is still a possibility of re-infection, so annual cervical cancer screening is still necessary, and it is also recommended that they exercise appropriately in order to improve their resistance to other pathogens. For HPV-infected patients, it is recommended that they go to the gynecology department of regular hospitals, and under the guidance of doctors, they should be actively treated with interferon and surgery, so as not to cause cervical cancer and other lesions that will affect their quality of life.
