Overview

Molluscum contagiosum is a common viral skin infection producing small, firm, dome-shaped bumps with a tiny dimple in the centre. It is caused by a poxvirus, it is harmless, and it clears completely on its own without any treatment.

The catch is the timescale: it typically takes 12 to 18 months, and occasionally up to two years. That is longer than anyone expects, and not knowing it is why families end up trying one remedy after another.

Two things are worth understanding before you decide what to do.

Treatment is usually not recommended in children. The available treatments are uncomfortable, can scar, and are being used against something that will disappear by itself and leave nothing behind. Leaving it alone is the recommended approach, and it is a choice made on evidence rather than a shrug.

And when the spots suddenly become red, swollen and crusted, that usually means it is ending. This is called the beginning-of-the-end sign. It looks infected, it commonly gets treated with antibiotics, and it is in fact the immune system finally clearing the virus — the last stage before the spots go for good.

Common symptoms

What the spots look like

  • Small, firm, raised bumps, typically 2 to 5mm across
  • A tiny dimple or pit in the centre — the characteristic feature that identifies them
  • Pearly, flesh-coloured or pinkish, sometimes with a waxy look
  • Usually in clusters, often in a line where skin has been scratched
  • Anywhere from a handful to dozens

Where they appear

  • Children: trunk, armpits, backs of the knees, inner elbows, face and neck
  • Adults: lower abdomen, groin, inner thighs and genitals — where transmission is usually sexual
  • In warm moist skin folds, and anywhere skin rubs
  • Spread by shaving, which drags the virus along the razor's path

Associated features

  • Usually painless and not itchy
  • An eczema-like rash around the spots — very common, itchy, and worth treating in its own right
  • Children with eczema tend to get more spots, over a wider area, because scratching spreads them

The beginning-of-the-end sign

Spots becoming red, swollen, tender and crusted, often several at once. It looks alarming and looks infected. In fact it is the immune system mounting a response, and it signals that the whole thing is about to resolve — usually within weeks. It is frequently mistaken for bacterial infection and treated with antibiotics that were never needed.

What warrants a proper look

  • A spot that is growing rapidly, bleeding, ulcerated or unusually large
  • Spots on the eyelid, or any eye irritation or redness
  • Genital spots in a child — which need sensitive assessment
  • Very extensive or persistent molluscum in an adult — where an underlying immune problem, including undiagnosed HIV, is worth considering

Causes and risk factors

The virus

Molluscum contagiosum virus, a poxvirus that infects only the top layers of skin. It does not go anywhere else in the body and causes no internal illness.

How it spreads

  • Direct skin-to-skin contact — the main route
  • Scratching, which spreads it across your own skin — which is why spots appear in lines
  • Shaving, particularly in the genital area in adults
  • Shared towels, flannels, bath water and swimming aids
  • Sexual contact in adults, where genital molluscum is usually acquired that way

Who gets it

  • Children between about one and ten — by far the commonest group
  • Children with eczema, who get more and worse
  • Swimmers, and children who share baths
  • Sexually active adults, in the genital area
  • People who are immunosuppressed, where it can be extensive and persistent

What it is not

  • Not a sign of poor hygiene. It is extremely common in perfectly clean households, and this reassurance matters to a lot of embarrassed parents
  • Not dangerous, and not a threat to health
  • Not related to warts, though the two are often confused. Warts are caused by a different virus, feel rough, and have no central dimple

What else it might be

Warts, milia, chickenpox early on, or in an adult with widespread lesions a fungal infection that can look similar in immunosuppression — which is one reason extensive adult molluscum gets a broader look.

How it is diagnosed

Molluscum is diagnosed by appearance, and a clear close-up photograph is usually all that is needed — the central dimple is distinctive. This suits a remote consultation well.

What we assess

  • The appearance and distribution of the spots
  • How long they have been there, and whether they are spreading
  • Whether any are inflamed — and whether that is the beginning-of-the-end sign rather than infection
  • Any eczema, which needs treating alongside
  • Age, and in adults whether the distribution is genital
  • Immune status, and any relevant medication

Tests

None needed in the typical case. We consider:

  • STI screening in adults with genital molluscum, since it is usually sexually acquired and other infections travel with it
  • An HIV test where molluscum is very extensive, unusually large or persistent in an adult — offered with an explanation of why, not simply added to a form

What needs seeing in person

  • Spots on or near the eyelid
  • Any lesion that is growing rapidly, bleeding or ulcerated
  • Genital spots in a child — which need careful, sensitive assessment
  • Anything we cannot confidently identify from a photograph

How we treat it online

1. The recommended approach: leave it alone

For most children, no treatment is the correct treatment. Molluscum resolves completely and usually without scarring. The available treatments hurt, can cause scarring, and are being used on something that will go by itself.

What we can usefully do is confirm the diagnosis, explain the timescale honestly, and treat the things that are actually causing bother.

2. Treat the eczema, which is what usually itches

The itchy rash around the spots responds to emollients and a mild topical steroid. This is the most useful prescription in most cases — it reduces scratching, which reduces spread, and it makes the child considerably more comfortable.

3. Where treatment is worth considering

  • Adults with genital molluscum, to reduce transmission — usually cryotherapy at a clinic
  • Spots in a cosmetically difficult site causing genuine distress
  • Anyone immunosuppressed with extensive disease
  • Options include cryotherapy, and topical treatments including potassium hydroxide solution, all of which sting and none of which are pleasant for a small child

4. When it looks infected

Red, crusted, angry-looking spots are usually the beginning-of-the-end sign, not bacterial infection — and they mean resolution is close. Genuine infection spreads beyond the spots into the surrounding skin, with warmth, increasing pain and often fever. Where that is the picture we prescribe antibiotics; where it is not, we explain rather than prescribe.

5. What we will not do

  • Prescribe painful treatments for a young child with a harmless self-limiting condition
  • Prescribe antibiotics for the beginning-of-the-end sign
  • Treat lesions on the eyelid remotely
  • Assess genital lesions in a child without specialist referral

Important

When to seek urgent help

Molluscum is not an emergency. Seek prompt medical attention for:

  • Spots on the eyelid with a red, painful or watering eye, or any change in vision
  • Rapidly spreading redness, warmth and swelling beyond the spots, with fever — genuine bacterial infection or cellulitis
  • Widespread painful blistering in a child with eczema, usually with fever — eczema herpeticum, which is a different and urgent problem

Book an appointment for:

  • Uncertainty about what the spots are
  • A lesion that is unusually large, growing quickly, bleeding or ulcerated
  • Genital molluscum in an adult — for treatment and for STI screening
  • Genital spots in a child, which need careful assessment
  • Troublesome eczema around the spots
  • Very extensive or persistent molluscum in an adult — which warrants a broader look at immune health
  • Distress about appearance, where treatment options are worth discussing

Prevention and self-care

The main thing: do not squeeze them

Picking, squeezing or scratching spreads the virus to new areas and causes the scarring that molluscum otherwise does not leave. The single most useful instruction here, and the hardest to follow — keep nails short, and cover spots with clothing or a plaster if a child cannot leave them alone.

Reducing spread

  • Do not share towels, flannels or bath sponges
  • Avoid shared baths where possible, particularly with younger siblings
  • Cover spots with clothing or a waterproof plaster for swimming
  • Do not shave over affected areas — in adults with genital molluscum this is the single biggest cause of spread
  • Wash hands after touching the spots

Managing the itch

Emollients generously and regularly, and a mild steroid where prescribed. Treating the surrounding eczema reduces scratching, and less scratching means fewer spots. It is the most effective indirect treatment available.

School, nursery and swimming

There is no exclusion from school or nursery, and no ban on swimming. Children should not be kept out of either. Cover the spots for swimming, use your own towel, and carry on as normal — the virus is far too common to be worth isolating anyone over.

What is not worth it

  • Tea tree oil, apple cider vinegar and "molluscum removal" kits sold online — no good evidence, and several cause chemical burns on children's skin
  • Duct tape and home cautery
  • Repeated antibiotic courses for the beginning-of-the-end sign
  • Anything painful used on a young child for a condition that clears on its own

What to expect

Individual spots last two to three months; new ones keep appearing while the infection is active; the whole thing takes 12 to 18 months, sometimes up to two years. That is normal, it is not a failure of anything you have done, and it ends completely.

NHS or private

Molluscum needs no treatment, and that is the most useful thing on this page. It clears by itself — usually within 12 to 18 months, sometimes longer — and it leaves no scar if left alone. Your NHS GP will confirm the diagnosis free.

The NHS generally does not treat it, and that is correct rather than a rationing decision. Every available treatment carries a risk of scarring or pigment change in exchange for shortening something that was going to resolve anyway.

What is worth knowing costs nothing: the spots often become red, crusted and inflamed shortly before they disappear, and that inflammation is a sign of resolution rather than infection — people frequently seek antibiotics at exactly the point the immune system has started clearing it.

Do not squeeze them. That spreads the virus and is the commonest reason a handful becomes fifty.

Where money is genuinely wasted: private cryotherapy or curettage for a child's self-limiting rash, and the various creams and “molluscum treatments” sold online, none of which have good evidence.

Where a consultation is worth it: if the diagnosis is uncertain, if spots are on the eyelid, if surrounding eczema needs treating — which genuinely helps the itch and reduces spread — or if lesions are extensive in someone immunosuppressed.

Evidence and guidelines

NICE Clinical Knowledge Summary, Molluscum contagiosum, is the principal reference. It recommends no treatment for most cases, noting spontaneous resolution typically within 18 months and the risk of scarring or pigmentary change from active treatments.

CKS explicitly advises against squeezing or scratching lesions, which promotes autoinoculation and spread.

CKS notes that lesions commonly become inflamed, red and tender shortly before resolving, and that this should not be mistaken for bacterial infection — the basis for the point above.

CKS advises treating surrounding eczema, which reduces itch, scratching and spread.

CKS sets out the circumstances warranting referral — diagnostic uncertainty, lesions near the eye or on the eyelid margin, extensive or persistent disease, and molluscum in immunosuppressed individuals, where it can be florid and treatment-resistant.

Exclusion from school or swimming is not recommended under UKHSA guidance.

Common questions

How long will this last?

Longer than you would like: typically 12 to 18 months, sometimes up to two years. Individual spots last two to three months, but new ones keep appearing while the infection is active. It does end completely, and usually without any mark — but knowing the real timescale up front saves a lot of fruitless remedy-hunting.

Should we treat it?

Usually not, in children. The treatments are uncomfortable, can scar, and are aimed at something that will disappear on its own. Leaving it alone is the recommended approach on the evidence, not a fob-off. Treatment is more often worthwhile for adults with genital lesions, or where spots are causing genuine distress.

The spots have gone red and angry. Are they infected?

Usually not — this is the beginning-of-the-end sign, and it means the immune system is clearing the virus. Resolution normally follows within weeks. Genuine infection spreads into the surrounding skin with warmth, increasing pain and often fever. The red crusted stage is very commonly given antibiotics it never needed.

Can my child go swimming and to nursery?

Yes to both. There is no exclusion for molluscum. Cover the spots with clothing or a waterproof plaster for swimming, use your own towel, and carry on. Keeping a child out of school or the pool for this is unnecessary and unfair to them.

Is it because we are not clean enough?

No, not remotely. Molluscum is extremely common in scrupulously clean households — it spreads by ordinary skin contact between children, and hygiene has very little to do with it.

Why does my child keep getting more?

Mostly from scratching, which carries the virus to new skin — which is why spots appear in lines. Treating the itchy eczema around them is the most effective way to reduce spread, along with keeping nails short and covering spots the child cannot leave alone.

Will it leave scars?

Not usually — molluscum heals cleanly if left alone. The scars people have are almost always from squeezing, picking or scratching, or occasionally from treatment. Which is the strongest argument for leaving it be.

I'm an adult with these in my groin. What does that mean?

In adults, genital molluscum is usually sexually transmitted, so full STI screening is worth doing alongside. Treatment — usually cryotherapy — is more often recommended than in children, to reduce passing it on. And do not shave the area: shaving is the main reason it spreads.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
