You notice a few small, smooth, pearly bumps on your child’s tummy or behind the knee. They don’t seem to hurt, but they’re slowly multiplying — and you’re worried. Most likely, these are molluscum contagiosum, sometimes called “water warts.” Take a breath: this is one of the most common, and most harmless, skin infections in childhood.
Quick Answer
Molluscum contagiosum is a common, harmless viral skin infection in children. It shows up as small, firm, round, pearly or flesh-coloured bumps, often with a tiny dimple in the centre. It spreads by skin-to-skin contact, sharing towels or bath water, and by the child scratching one bump and seeding others. The good news: it almost always clears on its own, though this can take several months and sometimes up to 12–18 months. The most important care is to not scratch, squeeze or pick the bumps. See a doctor if a bump becomes red, swollen or has pus, if bumps appear near the eye, if they are very widespread, or if you are simply unsure what they are.
What Is Molluscum Contagiosum
Molluscum contagiosum is caused by a pox virus (the molluscum contagiosum virus). When it infects the top layer of skin, it produces the characteristic bumps.
What the bumps look like:
- Small, usually a few millimetres across (some can grow a little larger)
- Firm, round and raised
- Pearly, flesh-coloured or pink, often shiny
- A tiny dimple or pit in the centre is the classic sign
- They can appear singly or in clusters
They can show up almost anywhere — commonly the trunk, armpits, behind the knees, the arms and the face. They are usually not painful, though they can sometimes itch a little or look red if irritated.
How It Spreads
Molluscum spreads easily but in predictable ways:
- Skin-to-skin contact with another person who has the bumps
- Sharing items like towels, clothes, bath water, sponges or bath toys
- Scratching: when a child scratches a bump and then touches another part of their own skin, new bumps can appear there. This is why bumps often spread to nearby areas on the same child.
Because of this, the simple habits below matter more than any treatment.
It’s Harmless and Clears on Its Own
This is the part worth holding onto: molluscum is harmless and the body’s own immune system clears it without any treatment in most children.
The catch is patience. It often takes several months to resolve, and in some children it can take around 12 to 18 months, occasionally longer. While the body is still clearing it, you may keep seeing new bumps appear even as older ones fade — this does not mean things are getting worse. Once the immune system catches up, the bumps go away, usually without leaving a scar (as long as they haven’t been picked or scratched raw).
Because it clears on its own, “watchful waiting” — simply caring for the skin and letting time do the work — is a perfectly reasonable approach for most children, and treatment is often not needed at all.
Care at Home
The aim of home care is to stop the spread and avoid complications:
- Don’t scratch, squeeze or pick the bumps. This spreads the virus to other areas and can introduce bacteria, leading to infection or scarring.
- Keep nails short so scratching does less damage and spreads less.
- Cover the bumps where practical (for example with clothing or a light dressing), especially if your child tends to scratch them.
- Don’t share towels, washcloths, clothes or bath water with other children. Give your child their own towel.
- Pat dry gently rather than rubbing the area.
- School and play are usually fine. Children can normally continue going to school and playing as usual. It’s sensible to avoid skin-to-skin contact sports (like wrestling) while the bumps are active, and to keep bumps covered during swimming.
Treatment — A Doctor’s Decision If Needed
Most cases are simply left alone to clear naturally. Some bumps are treated only when there’s a good reason — for example if they are very widespread, in an awkward spot, getting infected, or genuinely bothering the child.
If treatment is being considered, that is a decision for a doctor or dermatologist to make and carry out. Treatments are not always recommended for children, and what suits one child may not suit another.
Please do not try home “removal” methods — picking, scraping, applying household substances or over-the-counter products meant for warts. These can damage the skin, spread the infection and cause scarring. Let a doctor guide any active treatment.
When to See a Doctor
Reach out to your paediatrician or dermatologist if:
- A bump becomes red, swollen, painful, warm or has pus — this can mean a bacterial infection
- Bumps appear on the eyelid or near the eye
- The bumps are very widespread or spreading quickly
- Your child has a weak immune system or another significant health condition
- Your child has eczema that is flaring up around the bumps
- You are not sure the bumps are molluscum at all
Indian Context
A few things make molluscum a familiar visitor in Indian homes. Shared bathing, common towels and bath buckets between siblings make it easy for the virus to pass from one child to another — giving each child their own towel and avoiding shared bath water helps a lot. The warm, humid climate and plenty of sweaty outdoor play can keep skin irritated, so gentle drying and short nails are useful habits.
Most importantly, resist the urge to pick at the bumps or reach for a home remedy or a chemist’s wart product. These often do more harm than good. Molluscum looks alarming because it lingers and multiplies, but it is genuinely harmless and self-limiting. Patience, gentle skin care and a calm household are the real treatment.
Frequently Asked Questions
Q: Are these bumps dangerous or a sign of something serious?
A: No. Molluscum contagiosum is a common, harmless viral skin infection. It is not dangerous and it does not signal an underlying serious illness in an otherwise healthy child.
Q: How long will the bumps last?
A: They usually clear on their own, but it takes time — often several months, and sometimes up to around 12 to 18 months. New bumps may keep appearing until the immune system fully clears the virus.
Q: Can my child go to school and play with friends?
A: Yes, in most cases. Children can usually attend school and play normally. Keep bumps covered where you can, avoid sharing towels, and skip skin-to-skin contact sports while the bumps are active.
Q: Will the bumps leave a scar?
A: Usually not, if they are left alone to heal naturally. Scarring is more likely when bumps are scratched, squeezed or picked, which is exactly why we advise leaving them be.
Q: Should I get them removed?
A: Most don’t need removal and clear on their own. If they are widespread, infected, near the eye or really bothering your child, ask a doctor — any treatment should be their decision, not a home attempt.
