Human papillomavirus (HPV) conversions do not recur, but can re-infect.
HPV is a common infection transmitted sexually, with the highest rates of HPV infection in young and sexually active women, and the peak age for HPV infection is between 18-28 years old.
Although young women have a high rate of HPV infection, the vast majority will clear up through their own immunity within a short period of time. However, there is still the possibility of recurrent infections, and there are also cases of simultaneous infection with several different types of HPV. Although the rate of new infections in women decreases due to age, some older women are more prone to persistent HPV infections because their immune function declines with age.
Therefore, even if HPV turns negative and does not recur, there is still a possibility of re-infection. HPV conversion needs to be confirmed at least twice, with a 3-month interval between tests, or else there is the possibility of temporary negativity in between.
Once HPV has become negative, it is necessary to avoid transmission of HPV by sexual partners and to wear condoms appropriately to avoid spreading the virus. After HPV conversion, HPV vaccination should be administered as early as possible to prevent re-infection.
