Hello,
According to Merck manual, prolonged or repeated contact is necessary for the virus to spread, warts are most often spread from one area of the body to another, but they can spread also from one person to another.
For small warts, several medications(like podophyllum resin, Podofilox (Condylox), Trichloroacetic and bichloroacetic acids, Imiquimod 5% cream and interferons) are available, which can be applied directly to the surface of the warts. Other treatment options include electrical cautery, surgical removal, Carbon dioxide laser treatment and electrodesiccation.
I sincerely suggest you to discuss these treatment options with a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
