Molluscum Contagiosum

What is molluscum contagiosum?

Molluscum contagiosum is a skin infection that causes small spots on your skin. It sounds scary, but it's actually quite harmless and very common, especially in children.

The infection is caused by a virus. Don't worry - it's not dangerous and usually goes away by itself without needing any treatment.

What do the spots look like?

The spots are quite easy to spot once you know what to look for:

• They're small - about 2 to 5mm wide (roughly the size of a match head)
• They're raised up from the skin like little domes
• They have a shiny appearance
• There's usually a small white dimple or dent in the middle
• They often appear in groups together

In children, you'll usually see spots on the body, especially in skin folds like:

• The groin area
• Behind the knees
• Under the arms

In adults who catch it through close contact, spots might appear around:

• The lower tummy
• Genital area
• Thighs

If someone has a weak immune system (like people having chemotherapy), they might get spots on their face or around their eyes, or have larger or more spots than usual.

How do you catch it?

Molluscum contagiosum spreads through direct skin-to-skin contact. This means touching someone who has the infection.

The good news is that the chance of passing it on during normal daily activities is quite small. Children with the infection can usually still go to school and play with friends as normal.

How long does it last?

Most spots clear up completely within 18 months without any treatment. Your body's immune system learns to fight the virus and gets rid of it naturally.

Looking after yourself or your child

While waiting for the spots to clear up, there are some simple things you can do:

Do:

• Use unperfumed moisturiser to help with dry or itchy skin
• Hold a damp, cool towel against itchy areas
• Have cool baths to soothe the skin
• Keep the area covered, especially when swimming (use waterproof plasters)
• Use condoms during sex if you're infected

Don't:

• Squeeze or scratch the spots - this can cause infection or scarring
• Share baths, towels, bedding, or clothes with others

When to speak to your GP

You should see your GP if:

• You're not sure the spots are molluscum contagiosum
• The spots become very itchy, painful, swollen, or crusty
• You have spots near your eyes
• The spots are affecting your daily life significantly

Treatment options

Most people don't need treatment because the infection clears up naturally. However, if the spots are causing problems, your GP might suggest:

• Antibiotic cream if the spots become infected
• Steroid cream for itchy or sore skin

If you have lots of spots, they're near your eyes, or you have a weak immune system, your GP might refer you to a skin specialist for further help.

Remember, molluscum contagiosum might look concerning, but it's usually harmless and will clear up on its own with time and patience.
