Introduction

Whether filiform warts will recur after laser treatment depends on the treatment outcome and postoperative care. If the root of the wart was completely removed during laser treatment and proper postoperative protection is maintained, recurrence is generally unlikely. However, if the treatment was incomplete or if there are postoperative triggering factors, recurrence may occur. To reduce the likelihood of recurrence after laser treatment for filiform warts, avoid contact with contaminated water until the treated area has fully healed.

　　Laser usually refers to laser therapy. Whether filiform warts recur after laser treatment depends on the treatment process and postoperative care. If the root of the wart has been completely removed during laser treatment and proper postoperative protection is in place, recurrence is generally unlikely; however, if the treatment was incomplete or there are postoperative inducing factors, recurrence may occur. A detailed analysis is as follows:

　　If the doctor can accurately target the root of the wart during laser treatment, completely removing the wart tissue with appropriate energy, and the patient maintains cleanliness and dryness of the treated area after treatment, avoiding scratching or friction that may cause skin damage, the probability of recurrence will be significantly reduced, and long-term remission can be achieved for most patients.

　　When the root of the wart is not completely removed by laser treatment, residual viral tissue may proliferate again under favorable conditions, gradually forming new warts. Additionally, if the patient's immunity is low after surgery or they frequently stay in damp and unhygienic environments, the risk of reinfection or spread of human papillomavirus increases, which may lead to the reappearance of filiform warts after treatment.

　　To reduce the probability of recurrence after laser treatment for filiform warts, contact with sewage should be avoided before the treated area heals to prevent infection. Additionally, maintaining a regular lifestyle, balanced diet, moderate exercise, and enhancing personal immunity are recommended.

Do filiform warts spread to family members?

In general, filiform warts can be contagious to family members, but not all contact leads to transmission. The likelihood of transmission depends on factors such as the mode of contact and the skin condition of family members. It is important to avoid direct or indirect close contact in daily life to reduce the risk of infection. To minimize the risk of transmitting the infection to family members, patients should use personal hygiene items separately and regularly wash and disinfect towels, clothing, and other items.
