Molluscum contagiosum is a skin infection that causes small pearly or
flesh-colored bumps. The bumps may be clear, and the center often is indented.
The infection is caused by a virus. The virus is easily spread but is not
The bumps are round with a dimple in the center. They are a little smaller in size than the eraser on the end of a pencil. The bumps don't cause pain. They may
appear alone or in groups. They most often appear on the trunk, face, eyelids,
or genital area. The
bumps may become inflamed and turn red as your body fights the virus.
People who have a
weakened immune system may have dozens of larger bumps. These may need special treatment.
commonly spreads through skin-to-skin contact. This includes sexual contact or
touching the bumps and then touching the skin. Touching an object that has the
virus on it, such as a towel, also can spread the infection. The virus can
spread from one part of the body to another. Or it can spread to other people,
such as among children at day care or school. The infection is contagious until
the bumps are gone.
The time from exposure to the virus until the bumps appear usually is 2
to 7 weeks, but it can take up to 6 months.1

Molluscum contagiosum is most common in children, especially those younger than age 12. In teens and
young adults, it usually is a sexually transmitted infection. But wrestlers,
swimmers, gymnasts, massage therapists, and people who use steam rooms and
saunas also can get it.
Molluscum contagiosum is more common in
warm, humid climates with crowded living conditions.
