Learn how to prevent and treat this common skin infection that affects people of all ages.
Molluscum contagiosum (mo-LUS-kum kun-tay-jee-OH-sum) is a relatively common viral infection of the skin that results in round, firm, painless bumps ranging in size from a pinhead to a pencil eraser. If the bumps are scratched or injured, the infection can spread to surrounding skin. Molluscum contagiosum also spreads through person-to-person contact and contact with infected objects.
Though most common in children, molluscum contagiosum can affect adults as well — particularly those with weakened immune systems. In adults with an otherwise normal immune system, molluscum contagiosum involving the genitals is considered a sexually transmitted infection.
The bumps associated with molluscum contagiosum usually disappear within a year without treatment but doctor-assisted removal is also an option.
Signs and symptoms of molluscum contagiosum include bumps on the skin that:
If you suspect you or your child has molluscum contagiosum, consult your primary care doctor.
The virus that causes molluscum contagiosum spreads easily through:
It's not clear if the molluscum contagiosum virus can spread in the chlorinated water found in swimming pools. Experts suspect that it's more likely that swimmers transmit the virus through shared use of towels; equipment, such as kickboards; or skin contact.
More widespread molluscum contagiosis infections may occur in people with weakened immune systems.
The bumps and the skin around them may become red and inflamed. This is thought to be an immune response to the infection. If scratched, these bumps can become infected. If lesions appear on the eyelids, pink eye (conjunctivitis) can develop.
To help prevent the spread of the virus:
Your doctor usually can diagnose molluscum contagiosum just by looking at it. If there's any doubt, he or she may take skin scrapings from the infected area and view them under a microscope.
Molluscum contagiosum usually gets better without treatment in six to 12 months. However, it's possible to continue developing bumps for up to five years. Once all of your bumps are gone, you're no longer contagious.
Doctors may recommend that the lesions be removed before they disappear on their own, particularly in adults, because they are so contagious. Treatments for molluscum contagiosum can be painful, so an anesthetic might be administered beforehand to lessen discomfort. Sometimes a combination of treatments may be used.
You'll likely start by visiting your or your child's primary care practitioner. However, in some cases when you call to set up an appointment, you may be referred immediately to a doctor who specializes in treating skin conditions (dermatologist).
Because appointments can be brief, and because there's often a lot of ground to cover, it's a good idea to be well-prepared for your appointment. Here's some information to help you get ready for your appointment, and know what to expect from your doctor.
Before your appointment, write a list that answers the following questions:
Your doctor is likely to ask you a number of questions. Being ready to answer them may reserve time to go over any points you want to spend more time on. Your doctor may ask:
