- Warts are common in children. Most cases occur between
ages 12-16 years.
- Up to 30% of warts disappear by themselves within 6
months. Most will disappear without any treatment within 3 years.
- The virus enters the skin after direct contact with
recently shed viruses kept alive in warm, moist environments such as a
locker room, or by direct contact with an infected person. The entry site
is often an area of recent injury. The incubation time-from when the virus
is contracted until a wart appears-can be 1-8 months.
- Contrary to popular mythology, touching a frog will not
give you warts.
- Common warts
(verrucae vulgaris): These common warts typically develop on the hand,
especially around the nail. Common warts are gray to flesh colored, raised
from the skin surface, and covered with rough, hornlike projections.
- Plantar warts
(verrucae plantaris): Plantar warts , by definition, occur on the plantar
surface, or bottom, of the foot. They usually occur in high-pressure areas
such as the heel and the metatarsal heads (just behind the
toes). Plantar warts usually grow into the skin, not outward
like common warts. This growing into the skin makes plantar
warts more difficult to treat.
- Flat warts (verrucae
plana): Flat warts are most commonly seen on the face and the back of the
hands. They usually appear as small individual bumps about 1/4 inch
across. Flat warts may spread rapidly on the face from the activities
involved in shaving.
