Molluscum contagiosum is a harmless viral infection of the skin. Molluscum contagiosum can occur at any age but is most common in young children. It is NOT a sign of a problem with the immune system.
The molluscum virus is spread from the skin of one person to another. Close, direct contact is usually necessary to spread the virus, but it can be spread from shared towels or bathing with an infected person. Some experts believe that molluscum may also be spread in swimming pools. Scratching the bumps may also cause them to spread.
