Common warts are infections caused by the human papillomavirus, commonly known as "prickly warts." Using vinegar to soak them is ineffective. It is necessary to enhance local cleanliness, with physical treatment methods being the first choice, such as cryotherapy with liquid nitrogen or combined photodynamic therapy. Treatments may also include laser or surgical options, supported by immunological aids, such as oral thymopentin enteric capsules, and possibly supplemented by Avi A to promote the regression of the warts. Additionally, topical applications of interferon gel and tazarotene cream help inhibit viral replication and soften the keratin layer, respectively. Treatment usually requires about three to four weeks, with follow-up visits every one to two weeks. The cryotherapy can be administered in multiple sessions to prevent picking and the formation of injuries. (Medication should be used under the guidance of a physician.)
