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.

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.
