Molluscum Contagiosum
What is molluscum contagiosum?
Molluscum contagiosum is a skin condition caused by a virus. It causes small pink
or skin-colored bumps on the skin. They may spread or form lines when scratched. Almost
any area of skin can be affected. Common sites include the face, neck, armpit, arms,
hands, and genitals.
The rash spreads easily from one part of the body to another. It spreads through scratching
or other contact. It can also spread from person to person. This often happens through
shared clothing, towels, or objects such as shared sports gear. It can spread during
contact sports or sexual contact.
The bumps often go away in about 2 to 12 months. In rare cases, they last 3 to 5 years.

What causes molluscum contagiosum?
The condition is caused by a virus called a poxvirus. It is most common in children
and teens, but it can affect adults. The virus is most often spread through skin contact
with an infected person. It can be spread through:
The virus can also spread on your own skin by scratching or shaving the area with
bumps.
Who is at risk for molluscum contagiosum?
You are more at risk for molluscum contagiosum if you:
-
Have been in direct contact with a person who has the condition
-
Have a weakened immune system. This includes having HIV infection, cancer, diabetes,
or taking medicines that suppress the immune system.
What are the symptoms of molluscum contagiosum?
Symptoms can appear 1 to 6 weeks after contact with the virus. They can occur a bit
differently in each person. They can include bumps on the skin that are small and
pink or skin-colored. The bumps may itch. They may be round like a dome, and then
develop a sunken center. The bumps can form alone or in groups or clusters.
The symptoms of molluscum contagiosum can seem like other health conditions. Make
sure to see your healthcare provider for a diagnosis.
How is molluscum contagiosum diagnosed?
Your healthcare provider will ask about your symptoms and health history. They will
give you a physical exam. This will include a full skin exam to be sure all affected
areas are treated.
In some cases, your provider may do a skin biopsy. They will remove a small piece
of skin to send to a lab.
How is molluscum contagiosum treated?
Treatment will depend on your symptoms, your age, and your general health. It will
also depend on how severe the condition is.
In most cases, the bumps will heal without treatment over 2 to 12 months. In rare
cases, they last 3 to 5 years.
You may have treatment such as:
-
Removal of the bumps. Your healthcare provider may do this by freezing them (cryotherapy), or using a small
blade, a curette, electric sparks, or lasers.
-
Medicine on the skin. This may help the bumps clear up more quickly. Blistering medicines or medicine that
helps stimulate the immune system may help.
Talk with your healthcare providers about the risks, benefits, and possible side effects
of all treatments.
What are possible complications of molluscum contagiosum?
In some people, the bumps may lead to scarring of the skin. Removing the bumps may
also cause scarring.
What can I do to prevent molluscum contagiosum?
You can prevent this condition by not having contact with the skin or bath towels
of people who have the virus.
How to manage molluscum contagiosum
While you have the virus:
-
You are contagious. Protect other people from direct contact with your affected skin
areas.
-
Don’t scratch or pick at the rash. Scratching spreads the infection. If needed, cover
affected skin with bandages to help prevent scratching.
-
Don’t shave the bumps. This can also spread the virus on your own skin.
-
Wash your hands for at least 20 seconds before and after caring for the rash.
-
Don’t share towels, washcloths, or clothing with anyone.
-
Don’t scratch or pick at any areas that have bumps.
-
Don’t have sex if the bumps are in the genital area.
-
If you play contact sports or other activities that involve skin-to-skin contact,
cover all affected skin with clothing or bandages.
-
Don’t swim in public pools until the rash goes away.
When should I call my healthcare provider?
Call the healthcare provider if you have:
-
Bumps that appear on a new part of the body or seem to be spreading quickly
-
Signs of infection, such as warmth, pain, oozing, redness, or fever
