Target population Warts can affect people of any age, but they are most common between the ages 12– 16. It is estimated that 20% of schoolchildren and about 10% of the general population have warts. Those with HIV, organ transplants, or on chemotherapy have a higher incidence of warts due to their weakened immune system.

Signs and Symptoms Warts may occur singly or in multiples and often have multiple small black "dots" at the surface from tiny blood vessels. Common warts - are rough, thick, skin-colored, pink, or white bumps from 1 mm to over 10 mm in size, often on the hands, face, elbows, and knees.
Filiform warts - are long and narrow, like tufts of thread, and usually small at the base (1–3 mm); they often affect the face, eyelids, or nose area. Flat warts- are very slightly raised, smooth, 1–5 mm, skin-colored bumps that may appear in a line from self-inoculation from scratching or widely from shaving. They are often seen on the face, hands, or shins.
Plantar warts - are thick, rough, callus-like, often tender areas of the soles of the feet, usually on the weight-bearing areas. Since they are painful, they are often thought to be corns.

Prevention If you know of anyone who has warts, avoid skin contact with this person. Avoid using his towel and ensure that you clean your skin well regularly in order to avoid transfer of the infection. If you scratch your skin, clean it well with soap and use disinfectant because wounds are very susceptible to getting warts infection. Dont brush, clip, comb or shave areas that have warts, in order to avoid spreading the virus.
Dont use the same file or nail clipper on your warts as you use on your healthy nails. Dont bite your fingernails if you have warts near your fingernails. Dont pick at warts. Picking may spread the virus. Consider covering warts with an adhesive bandage to discourage picking. Keep your hands as dry as possible, because warts are more difficult to control in a moist environment. Wash your hands carefully after touching your warts. Use footwear in public showers or locker rooms.
