Warts are caused by the DNA-containing human papillomavirus (HPV). There are at least 63 genetically different types of HPVs. The virus enters the skin after direct contact with recently shed viruses kept alive in warm, moist environments.
Genital warts, caused by some types of HPV (human papillomavirus), can appear on the skin anywhere in the genital area as white or flesh-coloured, smooth, small bumps, or larger, fleshy, cauliflower-like lumps.
Avoid touching warts on others or stirring them on yourself (refrain from rubbing a warty finger across your face). Wear shower shoes in the gym locker room to lower your risk of option up the virus that causes plantar warts.
