Home > Health Library > Molluscum Contagiosum
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 harmful.
This infection 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.
The infection is more common in warm, humid climates with crowded living conditions.
The molluscum contagiosum virus 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 in some cases it can take up to 6 months.
Molluscum contagiosum causes small pearly or flesh-colored bumps.
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.
To diagnose molluscum contagiosum, your doctor will do a physical exam and may take a sample of the bumps for testing. If you have bumps in your genital area, your doctor may check for other sexually transmitted infections, such as genital herpes.
In most cases, molluscum contagiosum doesn't need to be treated. The bumps usually go away on their own in 6 to 9 months.
But people sometimes ask that the condition be treated, especially if it lasts a long time—the bumps can sometimes last for years. And doctors usually recommend treatment for these bumps if they are in the genital area. This prevents them from spreading.
If you need treatment, your choices may include:
Children may not need treatment, because the infection usually goes away on its own. But if your child needs treatment, talk to the doctor about how to prevent pain and scarring.
