The wart is a benign superfluous epidermis caused by human papilloma virus infection. In the treatment of warts, recombinant interferon is indeed a drug that can be used in the clinic, such as topical application of recombinant interferon, which is an interferon ointment, or intramuscular injection, or injection at the base of the wart, which can cause necrosis and loss of the wart, which is also more common in the treatment of warts. The actual fact is that there is not enough evidence to prove that interferon is a good treatment for warts, so it is not listed in the guidelines for systemic use of interferon for warts.
