1, condyloma acuminata damage or HPV is not completely removed Some scholars found that condyloma acuminata spontaneously recede or after treatment to remove warts there are still 45% of patients with latent HPV infection, of which 67% of patients show recurrence, which is seen to be the main reason for the recurrence of condyloma acuminata. 2, condyloma acuminata inoculation infection in the process of laser therapy or surgical excision therapy and other treatments may contain HPV lesion tissue contamination of other parts, such as condyloma acuminata lesions around or distal skin mucosa inoculation and condyloma acuminata occur. 3, HPV contaminated items infection such as patients used by HPV contaminated towels and other unprocessed, again after contact can cause condyloma acuminata recurrence. 4, the sexual partner HPV infection or condyloma acuminata exist patients with HPV infection or condyloma acuminata not thoroughly treated, patients condyloma acuminata cured again after their sexual contact can cause condyloma acuminata recurrence. 5, special parts of the presence of HPV some research found that some special parts of the HPV infection is not thoroughly treated and become HPV storage or shelter, such as the female cervical HPV infection, male urethra HPV infection 6, HPV infection subtype Some scholars found that the subtype of HPV infection and condyloma acuminata recurrence, such as HPV 16 and HPV 18 infection than HPV 6 and HPV 11 infection. The most important factor that causes warts and their recurrence is the presence of subclinical manifestations of warts and HPV latent infection. It has been reported that subclinical manifestations of condyloma acuminatum and latent HPV infection in extensive mucous membranes may cause recurrence of condyloma acuminatum in 30-70% of cases. The PCR technique found that 37.5% of the 72% of HPV positive people in the white acetate test negative non-lesion area relapsed. 8, the incompleteness of the body’s immune system Various internal and external factors cause the body’s immune function to decline, so that the body’s immune response and regulation disorder, eventually leading to a complete cellular immune system imbalance or defect is an important factor in the vicious circle of recurrence of condyloma acuminata. 9, other factors caused by the recurrence of condyloma acuminata other factors in the patient’s personal poor hygiene habits, male circumcision, female vulvovaginal infections and the increase in secretions caused by the local moist environment.
