What causes molluscum contagiosum?

Molluscum contagiosum is caused by a virus. The virus may first enter your body through a break in the skin, such as a cut. It can then spread to other parts of your body by touching, shaving, or scratching a bump. It can also spread from person to person by touch. Or it may be spread by sharing personal items like towels and razors.

Symptoms of molluscum contagiosum

Molluscum contagiosum causes small, dome-shaped bumps on the body. They often appear on the face, arms, legs, and trunk. In sexually active adults, the bumps may be found on the genitals or the skin around the groin area. These bumps are shiny and white or skin-colored. They also have a small dimple in the middle of them. They may sometimes get sore and swollen and cause redness and itching.

Treatment for molluscum contagiosum

If the bumps are not causing any problems, you may not need treatment. They may go away on their own in a few months or years. But they can also spread. You may need treatment if the infection is widespread or if you have a weak immune system. Treatment choices include:

• Cryotherapy. Putting liquid nitrogen on the bumps may freeze them off. A blister forms and the bump peels off.

• Physical removal. Your health care provider can use a few methods to scrape off or remove the bumps. This can sometimes be painful and might cause scarring.

• Medicine. Different gels, chemicals, or solutions may help clear the skin. 

When to contact your doctor

Contact your health care provider right away if:

• You have a fever of 100.4°F ( 38°C) or higher, or as directed by your provider.

• You have pain that gets worse.

• Your symptoms don’t get better, or they get worse.

• You have new symptoms.
