Quick answer. Molluscum contagiosum is a common, harmless viral skin infection that causes small, pearly, dome-shaped bumps, most often in children. It is contagious but usually clears on its own over time, and treatment is optional.
Molluscum contagiosum is a viral skin infection that produces small, smooth, pearly bumps on the skin. It is very common, particularly in young children, and although the bumps can spread and may linger for months, the infection is harmless and tends to clear up by itself without leaving scars. The name reflects how easily it passes from person to person through skin contact and shared items.
This guide explains what molluscum contagiosum is, what the bumps look like, how it spreads, how doctors recognise it and what the treatment choices are, including why doing nothing is often perfectly reasonable. It also covers practical advice about childcare and school in Singapore and when it is worth seeing a dermatologist. The overall message is reassuring: for most people molluscum is a minor, self-limiting condition.

What is molluscum contagiosum?
Molluscum contagiosum is a skin infection caused by a pox virus. It leads to clusters of small, firm bumps on the skin that are typically pearly or flesh-coloured and often have a tiny dimple in the centre. The condition is widespread and especially common in young children, though it can affect people of any age.
It is a benign, self-limiting infection, which means it usually resolves on its own without treatment over a period of months. In Singapore it is seen commonly in children and is generally a minor nuisance rather than a cause for serious concern. The bumps can appear anywhere on the skin, though they tend to spare the palms and soles.
Symptoms & signs
The hallmark of molluscum contagiosum is its distinctive bumps. Typical features include:
- Small, firm, raised bumps that are smooth and dome-shaped
- A pearly or skin-coloured appearance, often with a tiny central dimple
- Usually painless, although they can occasionally become itchy, red or inflamed
- Bumps appearing in clusters, often on the trunk, arms, legs, face or skin folds
- New bumps appearing over time, especially where the skin has been scratched
The bumps may become red and crusted as the body clears them, which is part of the natural healing process.
How it spreads & who is at risk
Molluscum contagiosum spreads through direct skin-to-skin contact with someone who has it, and through contact with contaminated items such as towels, clothing, bath sponges or toys. Scratching the bumps can spread the virus to other areas of the person’s own skin, leading to new bumps nearby.
Children are most commonly affected, partly because of close contact during play and shared items. People with eczema or with weakened immune systems may develop more widespread bumps. In adults, it can sometimes spread through sexual contact, in which case bumps may appear around the genital area. Good hygiene and not sharing personal items help limit spread.
How it is diagnosed
A doctor can usually diagnose molluscum contagiosum simply by looking at the characteristic bumps, with their pearly appearance and central dimple. In most cases no tests are needed. Occasionally, if the diagnosis is uncertain or the bumps look unusual, a doctor may:
- Examine the skin more closely with magnification
- Take a small sample from a bump to examine under a microscope
A clear diagnosis is reassuring, as it confirms the condition is benign and self-limiting, and helps distinguish it from other skin bumps.
Treatment options
Because molluscum contagiosum usually clears on its own and treatments can sometimes irritate the skin, watchful waiting is a common and reasonable choice, especially in children. Treatment may be considered if the bumps are widespread, bothersome, in a sensitive area, or slow to clear. Options a doctor might discuss include:
- No treatment: letting the bumps resolve naturally over time
- Topical treatments: creams or solutions applied to the bumps
- Physical removal: procedures such as freezing (cryotherapy) or careful removal of the central core by a clinician
To reduce spread, avoid scratching, keep the bumps covered where practical, and do not share towels or personal items. A dermatologist can advise on whether treatment is worthwhile for your situation.
When to see a doctor & which specialist
Molluscum contagiosum is harmless, but it is worth seeing a doctor to confirm the diagnosis or if the bumps are widespread, persistent or bothersome. See a doctor if:
- You are unsure what the bumps are, or they are changing
- The bumps are around the eyes or genitals, or there are many of them
- The skin becomes very red, painful, swollen or starts to weep, which could suggest a secondary infection
- You or your child has a weakened immune system or severe eczema
For childcare and school in Singapore, children with molluscum can usually continue to attend, with bumps kept covered where possible to limit spread, but follow current guidance from your doctor or the centre. Seek urgent care, and go to A&E or call 995, only in the rare event of a spreading skin infection with fever and feeling very unwell. For diagnosis and treatment of persistent or troublesome bumps, see a dermatologist through our directory of dermatologists in Singapore.
