Molluscum Contagiosum: Harmless but Persistent
Molluscum contagiosum is a common, harmless skin infection caused by a virus. It shows up as small, firm, dome shaped bumps, often with a tiny dimple in the centre. It is very common in children, spreads easily through everyday contact, and almost always clears on its own without treatment.
The bumps are usually painless and range from pinhead to pea sized. They can appear anywhere, though the arms, legs, tummy and folds of skin are common spots. There may be one or two, or clusters of twenty or more. Sometimes the skin around a bump turns pink or itchy, especially as the body starts to clear the virus.
It helps to know from the start that this is one of the most ordinary skin conditions of childhood. It is not a sign that your child is unwell or that anything has gone wrong. Most children are otherwise perfectly healthy the entire time the bumps are present.

The reassuring truth is that molluscum is self limiting. The immune system recognises the virus and clears it over time, usually within six to twelve months, though it can occasionally take longer. Once it clears, it rarely comes back and does not cause any lasting harm.
Because it settles on its own, watchful waiting is the standard approach in Australia for healthy children. There is no need to rush into treatment, and gently leaving the bumps alone is often the kindest choice. Picking or squeezing tends to spread them and can lead to scarring, so it is best avoided.
Children with sensitive skin, such as those with childhood eczema, can get more bumps, and the surrounding skin may become dry or itchy. That is worth mentioning to a doctor, but it still does not change the harmless nature of the condition itself.
Molluscum passes from person to person through direct skin contact, and sometimes through shared items that touch the skin, such as towels, bath sponges or wrestling mats. Within a family, siblings often pass it back and forth, which is completely normal and not a sign of poor hygiene.
A child can also spread it on their own skin by scratching one bump and then touching another area. This is called autoinoculation, and it is why gentle skin care and short nails help more than scrubbing.
Sensible steps include using separate towels where practical, avoiding sharing baths when there are many bumps, and covering bumps with clothing or a light dressing during close contact sports. These measures lower the risk a little, but they will not stop spread completely, and that is okay.
Two worries come up again and again, so it helps to set them straight. The first is swimming pools. Chlorinated water does not cause or meaningfully spread molluscum, and there is no need to keep your child out of the pool or away from swimming lessons. What matters more is not sharing towels, kickboards and other items straight after use.
The second myth is that molluscum means a house is unclean. It does not. This is an ordinary childhood virus that spreads through normal play and contact, and no amount of extra scrubbing will prevent it. Harsh soaps and vigorous washing can actually irritate the skin and make things worse.
Children do not need to be kept home from school or daycare. If you are ever unsure about exclusion, our guide to when a child is unwell and your centre's policy are good starting points.
For most healthy children, leaving molluscum alone is the right call. Treatment does not make it clear faster in every case, and some options can be uncomfortable for young skin, so the small bumps are usually best left to settle naturally while you get on with everyday life.
There are situations where a doctor may discuss options with you: bumps in an awkward or tender spot, a lot of surrounding eczema, ongoing infection, or a child who is very bothered by them. A GP can talk through the choices and what suits your child, without any pressure to act.
It is a different picture in conditions that spread differently, such as impetigo or school sores, a rash with fever like scarlet fever, or a viral rash like hand, foot and mouth disease. If you are unsure which you are looking at, a quick review clears it up.
Care that knows your child
Molluscum itself is not an emergency, but a review is sensible if a bump becomes red, hot, swollen, painful or starts oozing pus, which can point to a secondary skin infection that may need attention. The same goes for bumps near the eye, which are worth checking rather than treating at home.
Book a review too if you are simply not certain the bumps are molluscum, if they appear alongside fever or your child seeming unwell, or if the surrounding eczema is flaring and hard to settle. A doctor can confirm the diagnosis, usually just by looking, and put your mind at rest.
For a child with a weakened immune system, molluscum can behave differently, so mention any ongoing health conditions. In a genuine emergency, such as a severe allergic reaction or a very unwell child, call 000.
Abby Health is an online-first clinic, so you can show a doctor your child's skin and get clear advice from home, seven days a week. For something as common as molluscum, that often means reassurance and a plan for watchful waiting, rather than an unnecessary trip to a clinic.
You can choose to see the same doctor each time, so they know your child's history and can follow the bumps over the months it takes them to clear. To understand how consults work for little ones, see Abby for families and kids. When you are ready, you can schedule an appointment or book through our everyday family clinic. Bulk billed for eligible patients with a valid Medicare card. Strict eligibility criteria apply. This is general information only and not a substitute for personal medical advice; if your child is seriously unwell, call 000.
