Molluscum contagiosum is a skin infection that causes small pearly or flesh-coloured bumps. The bumps may be clear, and the centre often is indented. The infection is caused by a virus. The virus is easily spread but is not harmful.
The bumps are round with a dimple in the centre. 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.
The 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 daycare 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.
To prevent molluscum contagiosum from spreading:
Your doctor will do a physical examination 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 (STIs), 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 in some cases, they may last much longer-sometimes even for years.
Doctors usually recommend treatment for these bumps in the genital area to prevent them from spreading.
If you need treatment, your choices may include:
Children may not need treatment, because molluscum contagiosum usually goes away on its own. But if your child needs treatment, talk to your child's doctor about how to prevent pain and scarring.
Molluscum contagiosum is most common in children, especially those younger than age 12. In teenagers 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.
