The contagious wart is caused by the human papillomarvirus, otherwise known as HPV. Warts are easily spread through simple human contact, especially when there is a break in the skin. The most common warts are found on the hands, feet, arms or legs.
If you have a wart, there are several ways to treat it, including using salicylic acid, duct tape, retinoid cream, cantharidin or freezing. As long as the wart in not irritated or broken, salicylic acid can be applied twice a day directly to the wart. It may take several months for your warts to completely disappear, however. You can also use retinoid cream to help stop the growth of warts, but it generally doesn’t work as well as salicylic acid.
Another option is cantharidin, which is a chemical that kills the wart and skin beneath it. One of the most effective treatments for removing warts is freezing them with liquid nitrogen. This usually works after the very first treatment, and can be done at home or in a doctor’s office. The only draw back of freezing is that it may cause some pain or blistering.
Want to try something a little non-traditional? Consider using duct tape to remove your wart. Apply a small piece of tape over the wart and leave it there for six days. Remove the tape and file down the wart with a pumice stone or nail file.
