Molluscum Contagiosum

What is molluscum contagiosum?

Molluscum contagiosum is a skin infection caused by a virus. It is a nuisance, but not dangerous.

How is molluscum contagiosum spread?

Molluscum contagiosum is passed from one person to another by direct skin-to-skin contact, including close contact with a sexual partner. It is possible that molluscum contagiosum is passed on by clothing or towels. The lumps can spread from one part of the body to another by scratching.

What are the symptoms of molluscum contagiosum?

The symptoms of molluscum contagiosum can appear within 1-6 weeks after exposure. Molluscum contagiosum first appears as very small (about 1/8 inch across), smooth, round, pearly bumps with indented cores in the middle. They may be on or around the pubic area, on the abdomen, or inner thighs. There may be one or two bumps or 10 to 20 or more than 50.

The bumps aren't painful but they may be itchy. They can get infected and become red and sore. However, redness and soreness can also mean that they are healing naturally. Check with your health care provider.

How is molluscum contagiosum treated?

Molluscum contagiosum bumps may go away by themselves, but treatment shortens how long you have them. Treatments usually are medicines applied to the lumps. The lumps may still take a couple of weeks to disappear after treatment. Without treatment, molluscum contagiosum can last for 6 months to 2 years.
