Warts
(common, plane and plantar)

Description
Warts are caused by a papova virus infection of the skin. Common warts develop on the skin of children and adolescents. They mainly occur on the knuckles, backs of hands and knees. Occasionally, common warts come out in a crop. Plane warts are flat-topped. They are most commonly found on the face and on the back of the hands. Plantar warts occur on the soles of the feet. They are found mostly in older children and adolescents.


Incubation Period
About four months, but ranges from 1-20 months.


Infectious Period
Unknown, but if untreated probably as long as warts can be seen.


Controlling the Spread of Infection
Do not exclude a child with warts. Treat warts if the affected area is exposed (for example, on the hands or legs). After treatment the warts are not contagious. The wart virus may enter via moist skin surfaces, such as abrasions and cuts. Therefore it is important to get children to: • dry hands well after washing them; • cover abrasions and cuts with bandaids or a clean dressing; and • wear shoes to protect the feet. Make sure that good handwashing and cleaning procedures are being practised.


Treatment
Warts will usually go away naturally, but this may take a long time. If treatment is necessary liquid nitrogen may be used. This is applied directly to the wart by a doctor. It freezes the warts, which usually disappear after several treatments. Alternatively, the doctor may choose to scrape warts or cut them out.
