Molluscum Contagiosum

Overview

Molluscum contagiosum is a common skin infection caused by a virus. It shows up as small, round, hard, and painless bumps. These bumps can be very tiny, like a pinhead, or a little bigger, about the size of a small eraser. If you scratch or hurt one of these bumps, the infection can easily spread to other parts of your skin. The virus is easily passed from one person to another through direct skin-to-skin contact, or by touching things that have the virus on them.

Kids are most likely to get this infection, but adults can get it too, especially if their immune system isn't working as well as it should. Adults with healthy immune systems can get it through sexual contact with someone who has the infection.

Usually, these bumps will go away on their own within a few months to a couple of years without any special treatment.

Symptoms

Molluscum contagiosum is a common skin infection that shows up as small, raised bumps. These bumps usually have a slightly indented or dotted center and are typically light-colored, like your skin. They're often round and smooth, and less than a quarter of an inch across (smaller than about 6 millimeters).

Kids often get these bumps on their face, torso, arms, or legs. In adults, the infection is sometimes spread through sexual contact. If this is the case, the bumps may appear on the genitals, lower belly, or inner thighs.

The bumps might also be itchy and a slightly pinkish color.

When to see a doctor

If you think you or your child might have molluscum contagiosum, it's important to talk to your doctor or other healthcare professional. Molluscum contagiosum is a skin infection that shows up as small, flesh-colored bumps. Seeing a doctor is the best way to get a proper diagnosis and treatment plan.

Causes

Molluscum contagiosum is a viral skin infection that's easily spread. The virus is contagious, meaning it can easily pass from one person to another. Here's how it spreads:

  • Direct contact: Touching someone who has molluscum contagiosum can spread the virus. This includes touching their skin directly, or even sharing items they've used, like towels, pool toys (like kickboards), or sports equipment (like wrestling mats).

  • Shared objects: The virus can live on surfaces. If someone with the infection touches a towel, kickboard, or wrestling mat, and then someone else touches the same object, they can get infected.

  • Water sources: If a pool or hot tub is contaminated with the virus, swimming in it can spread the infection. The virus can live in the water for a period of time.

  • Sexual contact: The virus can also be spread through sexual contact with someone who has the infection.

  • Scratching or rubbing: People sometimes have a tendency to scratch or rub the bumps or growths caused by molluscum contagiosum. This can spread the virus to other areas of the skin. It's important not to scratch or rub the affected area to prevent further spread. This is also important for preventing secondary infections from other bacteria or fungi.

In short, the virus is highly contagious and easily spread through various types of contact with infected people or contaminated objects. Keeping your hands clean and avoiding touching infected areas can help prevent the spread.

Risk factors

Molluscum contagiosum is a common skin condition, often seen in young children. Several factors can increase your risk of getting it.

  • Age: The infection is most frequently found in children between the ages of 1 and 10. This is because their immune systems are still developing.

  • Weakened Immune System: A weakened immune system makes it easier for the virus that causes molluscum contagiosum to take hold. This can happen due to various reasons, such as having certain medical conditions like leukemia or HIV, or undergoing cancer treatments. These treatments often suppress the immune response, making the body less able to fight off infections.

  • Skin Conditions: Having atopic dermatitis (also known as eczema) can also increase your risk. Atopic dermatitis is a skin condition that causes a rash. This rash can create openings in the skin, making it easier for the molluscum virus to enter and cause an infection.

Complications

Small, raised bumps can sometimes appear on the skin, and the skin around these bumps might get red and sore. This is often the body's immune system fighting off an infection. If you scratch these bumps, they can get a secondary infection and leave a scar. If sores or bumps show up near your eyes, it could lead to pink eye (conjunctivitis).

Prevention

To stop the spread of molluscum contagiosum:

  • Wash your hands often. Regular handwashing is key to preventing the spread of this skin infection. Wash your hands thoroughly with soap and water for at least 20 seconds, especially after touching your face, or after touching the affected areas.

  • Don't touch the bumps. Avoid touching or picking at the bumps. Shaving over the affected areas can spread the infection, so it's best to avoid shaving or using razors on these areas.

  • Don't share personal items. Sharing items like clothing, towels, and personal care items like razors, hairbrushes, and even utensils can spread the virus. Use your own individual items.

  • Avoid sexual contact if the bumps are near your genitals. If you have molluscum contagiosum on or near your genitals, it's important to avoid sexual contact until the bumps are completely gone and the infection is healed. This will help prevent spreading the infection to your partner.

  • Cover the bumps when around others. When you're around other people, it's a good idea to cover the bumps with clothing to prevent direct contact. Allowing the affected areas to breathe and air out when not around others is also beneficial for the skin's healing process. When swimming, use a waterproof bandage to cover the bumps to prevent spreading the virus through water.

Diagnosis

Doctors can usually tell if someone has molluscum contagiosum just by looking at the skin bumps. If they're not completely sure, they might take a small sample of skin from the affected area. This sample is then examined under a microscope to confirm the diagnosis.

Treatment

Molluscum contagiosum is a skin infection that usually goes away on its own within a timeframe of six months to two years. This means the bumps will eventually disappear, and you will no longer be able to spread the infection. However, even after the infection clears up, it's possible to get it again.

If the infection is very severe or covers a large area of your skin, your doctor might suggest seeing a dermatologist (a doctor specializing in skin conditions). A dermatologist can help discuss different treatment options.

If treatment is needed, there are several approaches. These might include:

  • Medicines to irritate the bumps: Some creams, like retinoic acid or benzoyl peroxide, can be used to irritate the bumps and help them heal.

  • Medicines to create blisters: A medicine called cantharidin can be used to create blisters around the bumps. This can help the bumps come off.

  • Scraping: In some cases, the bumps can be scraped off.

  • Freezing: Cryotherapy involves freezing the bumps to make them disappear.

  • Laser therapy: This is sometimes used, particularly if a person has a weakened immune system.

It's important to remember that some of these procedures can be uncomfortable, so your doctor may apply a numbing cream beforehand. Possible side effects of any treatment include infection and scarring. Your doctor will discuss the best approach for your specific situation.

Preparing for your appointment

To get help for skin problems, you'll probably first see your own doctor or a pediatrician (if it's a child). Or, you might be sent to a dermatologist, a doctor who specializes in skin conditions.

Getting ready for your appointment will make it easier and help your doctor understand your problem.

Before your visit, make a list of answers to these questions:

Your doctor will likely ask you these questions:

  • What are the symptoms? Describe the skin problem as clearly as you can. For example, are there red spots, itchy areas, blisters, or something else?
  • What makes the symptoms better or worse? Does anything seem to help or hurt the problem? For example, does scratching make it worse? Does a certain lotion help?
  • What medicines or supplements are you or your child taking? This includes all prescription drugs, over-the-counter medications, and vitamins or herbal supplements.
  • When did the symptoms start? Knowing the timeline is important.
  • Are the symptoms constant or do they come and go? Do they appear and disappear, or are they always present?
  • Have you or your child had similar problems before? If so, when and what were they like?
  • Has anyone else you know had similar skin problems? This could include family members or close friends.

This preparation will help your doctor understand the situation and make an accurate diagnosis.
