HPV infects the squamous epithelium, usually of the skin or genitals, but each HPV type is typically only able to infect a few specific areas on the body. There are about 130 known types of human papilloma viruses. Warts are caused by the human papilloma virus (HPV). Mosaic wart, a group of tightly clustered plantar-type warts, commonly on the hands or soles of the feet.Plantar wart ( verruca, verruca plantaris), a hard, sometimes painful lump, often with multiple black specks in the center usually only found on pressure points on the soles of the feet.Periungual wart, a cauliflower-like cluster of warts that occurs around the nails.Genital wart (venereal wart, condyloma acuminatum, verruca acuminata), a wart that occurs on the genitalia.Filiform or digitate wart, a thread- or finger-like wart, most common on the face, especially near the eyelids and lips.Flat wart ( verruca plana), a small, smooth flattened wart, flesh-coloured, which can occur in large numbers most common on the face, neck, hands, wrists and knees.Sometimes known as a Palmer wart or Junior wart. Common wart ( verruca vulgaris), a raised wart with roughened surface, most common on hands, but can grow anywhere on the body.Types Ī range of types of wart have been identified, varying in shape and site affected, as well as the type of human papillomavirus involved. Warts have been described at least as far back as 400 BC by Hippocrates. Prior to widespread adoption of the HPV vaccine, the estimated rate of genital warts in sexually active women was 12%. The estimated current rate of non-genital warts among the general population is 1–13%. Warts are very common, with most people being infected at some point in their lives. Treatment of genital warts differs from that of other types. In those who are otherwise healthy, they do not typically result in significant problems. A number of treatments may speed resolution, including salicylic acid applied to the skin and cryotherapy. Without treatment, most types of warts resolve in months to years. Genital warts are often sexually transmitted. A number of types exist, including "common warts", plantar warts, " filiform warts", and genital warts. The virus is believed to enter the body through skin that has been damaged slightly. Factors that increase the risk include use of public showers and pools, working with meat, eczema and a weak immune system. Warts are caused by infection with a type of human papillomavirus (HPV). While they usually occur on the hands and feet, they can also affect other locations. They typically do not result in other symptoms, except when on the bottom of the feet, where they may be painful. Warts are typically small, rough, hard growths that are similar in color to the rest of the skin.
