By Mayo Clinic staffMolluscum contagiosum is a relatively common viral infection of the skin that most often affects children. It results in firm bumps (papules) that are painless and usually disappear within a year without treatment. If the papules are scratched or injured, the infection can spread to surrounding skin.
Though common in children, molluscum may affect adults as well. In adults, molluscum contagiosum involving the genitals is considered a sexually transmitted disease (STD). The disorder may also be seen in adults with an altered immune system.
Molluscum contagiosum spreads through direct person-to-person contact and through contact with contaminated objects. Because it spreads easily, doctors often recommend medical treatment, especially for adults.
