This common viral infection most often affects young children, who pass it to each other through saliva.
In adults the virus results in lesions on the genitals, lower abdomen, buttocks or inner thighs. Most people with the infection do not have noticeable symptoms other than the lesions, which are painless wart-like bumps. However, in some cases the lesions may itch or become irritated.
This viral infection is passed between adults through sexual contact, exclusively.
The lesions often heal without treatment, although physicians may sometimes scrape them off or treat them with chemical irritants.
