Warts do not usually come back for 20 years, and the reappearance of warts after 20 years is usually a reinfection.
Condyloma acuminatum is a sexually transmitted disease that is more likely to recur. Because there is no specific drug for HPV virus, it is difficult to completely eliminate HPV virus through drugs, but in general, HPV virus is not endless replication and lead to permanent recurrence of warts.
Usually, in the early stage of HPV infection, that is, the first one or two years, the virus is relatively active, this time the disease recurrence chances are greater. The longer the virus has been in the body, the less active it is, so the chances of recurrence are less.
In the clinic, it is difficult to come across 20 years after the recurrence of warts, 20 years after the recurrence of warts is very likely to be re-infected. Warts can go to the hospital dermatology department.
