Molluscum


What is Molluscum?
Molluscum contagiosum is a very common viral skin infection initiated by the molluscum contagiosum virus (MCV). This infection results in small, firm, round, and painless bumps that appear on the skin’s surface. These bumps, also called lesions or papules, are usually flesh-colored, white, or pink and can have a dimple in the center. While molluscum contagiosum is generally harmless, it is transmittable and can spread through skin-to-skin contact or by touching contaminated objects.
Molluscum contagiosum often affects children but can also occur in adults, particularly those with impaired immune systems or those engaging in close physical contact, such as athletes or individuals in intimate relationships. The infection can appear anywhere on the body, but it is most common on the face, neck, arms, hands, and legs.
Symptoms of Molluscum Contagiosum
The primary symptom of molluscum contagiosum is the appearance of small, round bumps on the skin. Key characteristics include:
- Size: Lesions are typically 2-5 millimeters in diameter.
- Color: Flesh-colored, white, or pink with a central dimple or core.
- Texture: Firm and smooth to the touch.
- Number: Individuals may have a few bumps or several dozen, depending on the spread of the infection.
While molluscum contagiosum is generally painless, the bumps may become itchy or irritated. In some cases, scratching the lesions can lead to secondary bacterial infections, causing redness and swelling.
How Does Molluscum Contagiosum Spread?
Molluscum contagiosum spreads easily through direct skin-to-skin contact or by touching infected surfaces, such as towels, clothing, or toys. The virus thrives in environments where close contact is common, such as schools, daycares, gyms, or swimming pools.
Children are more susceptible to molluscum due to their frequent physical contact during play and shared use of personal items. Adults can also contract the virus, particularly if their immune system is compromised or if they engage in intimate contact with someone who has the infection.

Frequently Asked Questions
Is molluscum contagiosum dangerous?
No, molluscum contagiosum is typically a harmless skin condition, but it is contagious and can spread easily to others or other parts of the body.
Can molluscum contagiosum go away on its own?
Yes, molluscum contagiosum often resolves without treatment within 6-12 months. However, treatment can speed up the process and reduce the risk of spreading the virus.
Can adults get molluscum contagiosum?
Yes, while molluscum contagiosum is more common in children, adults, especially those with weakened immune systems or those who have close physical contact with an infected person, can also contract the virus.
What should I do if my child has molluscum contagiosum?
It’s important to keep the affected areas covered and teach your child to avoid scratching the bumps. If the condition worsens or spreads, consult with a dermatologist for treatment options.
