Molluscum Contagiosum: What Those Small Bumps Mean—and What to Do Next
You notice a few tiny, smooth bumps on your child’s arm after bath time. They don’t seem painful, but one has a little dip in the middle. A week later, there are more. Is it an allergy? A wart? Something contagious?
Molluscum contagiosum is a common viral skin infection that can look puzzling at first. It often affects children, but adults can get it too. The good news: in otherwise healthy people, it usually clears on its own. The trick is understanding how it spreads, caring for the skin without making things worse, and knowing when a clinician should take a look.
This guide explains what molluscum contagiosum looks like, how it spreads, what treatment options involve, and how to reduce the chance of passing it to others. It’s educational information, not a substitute for a medical diagnosis or personalized care.
What Is Molluscum Contagiosum?
Molluscum contagiosum is a skin infection caused by a poxvirus. It produces small, raised bumps—often called molluscum lesions—on the surface of the skin. The bumps are usually firm, smooth, and flesh-colored, pink, or pearly. Many have a tiny central indentation, sometimes described as a “dimple.”
The infection is generally limited to the skin. In healthy people, it does not usually cause serious illness, and it often resolves without treatment. However, the bumps can linger for months, spread to nearby areas, or become irritated and itchy.
What do the bumps look like?
Molluscum lesions are commonly:
Round, smooth, and slightly raised
About 2–5 millimeters wide, though they can be larger
Flesh-colored, white, pink, or pearly
Dimpled or indented in the center
Present as a single bump or clusters
They may appear anywhere, but common sites include the arms, legs, torso, armpits, and face. In adults, bumps around the genitals or lower abdomen can occur, particularly when infection is passed through intimate skin-to-skin contact.
A bump may become red, swollen, or crusted as the body starts fighting the virus. That change can be part of the natural clearing process, but it can also resemble a bacterial infection. If the area is increasingly painful, hot, rapidly worsening, or draining pus, seek medical advice.
Who gets molluscum contagiosum?
Anyone can get it. It is especially common in:
Children, particularly those under 10
People who have close skin-to-skin contact with someone who has the infection
Swimmers and people who share towels or sports equipment
People with eczema, because irritated or broken skin may make spread easier
People with weakened immune systems, who may develop more extensive or persistent lesions
Having molluscum does not mean someone is unclean. The virus spreads through ordinary contact, and children can pick it up during play or everyday activities.
Is it the same as a wart or herpes?
No. Molluscum contagiosum is caused by a different virus than common warts and herpes. Its characteristic smooth, dimpled bumps may help a clinician recognize it, but appearance alone is not always enough to be certain.
Other conditions—such as folliculitis, milia, acne, genital warts, or certain infections—can look similar. Avoid trying to diagnose or treat an unfamiliar rash yourself, especially if it is near the eyes or genitals, painful, spreading quickly, or affecting an adult’s genital area.
How Molluscum Spreads—and How to Limit It
The virus spreads when infected skin touches another person’s skin. It can also spread from one part of the body to another when someone scratches, rubs, or picks at the bumps. This is called autoinoculation.
Shared items may contribute to transmission, particularly when they have recently touched affected skin. Examples include towels, clothing, washcloths, sports gear, or razors. Swimming pools themselves are not necessarily the source; close contact and shared wet items around the pool may play a role.
Practical steps to reduce spread
You don’t need to isolate a child from normal life. Instead, focus on simple habits:
Keep bumps covered when practical. Use clothing or a watertight bandage during activities involving close contact. Replace the bandage if it becomes wet or dirty.
Discourage scratching and picking. Keep fingernails short and consider covering itchy areas, especially at night.
Don’t share personal items. Use separate towels, washcloths, clothing, razors, and sports equipment.
Wash hands regularly. This is especially helpful after touching or applying a product to affected skin.
Avoid shaving over lesions. Shaving can spread the virus across nearby skin.
Care for eczema. Ask a clinician how to manage itchy, inflamed skin without irritating the bumps.
Clean shared equipment. Follow the facility’s usual cleaning guidance for sports or exercise gear.
These measures lower the chance of spread, but they cannot eliminate it completely. Molluscum can be contagious before every bump is noticed, and close contact is difficult to avoid in families.
Can a child go to school, daycare, or swim?
In most cases, children with molluscum can attend school, daycare, and routine activities. Check local school or sports policies, particularly for contact sports or swimming programs.
For swimming, cover visible bumps with a watertight bandage when possible, and don’t share towels or swimwear. If lesions are in an area that cannot be covered, or the child has open or irritated skin, ask a healthcare professional or program staff for specific advice.
The goal is sensible risk reduction—not keeping a child away from friends for months.
What about intimate contact?
In adults, molluscum lesions around the genitals may spread through intimate skin-to-skin contact. A clinician can help confirm the cause and discuss treatment and precautions. Until the bumps have been assessed, avoid direct contact with the affected area. Condoms may reduce exposure but cannot cover all nearby skin, so they do not fully prevent transmission.
If genital bumps are new, don’t assume they are molluscum. Several conditions can look alike and require different care.
Diagnosis and Treatment: What to Expect
A clinician can often identify molluscum by examining the bumps. In typical cases, no test is needed. If the appearance is unusual, the lesions are in a sensitive area, or there is uncertainty about the diagnosis, the clinician may recommend additional assessment.
When is it reasonable to wait?
For many healthy children and adults, watchful waiting is a reasonable option. The immune system usually clears the infection over time, though the timeline varies. Lesions may disappear within several months, but some cases last longer—sometimes a year or more.
Waiting can make sense when:
The bumps are not painful or significantly itchy
They are not near the eyes or genitals
There are only a few lesions
The person is otherwise healthy
Treatment may cause more irritation or scarring than the bumps themselves
While waiting, avoid squeezing, cutting, or scraping lesions at home. These methods can cause pain, bleeding, infection, scarring, and further spread.
What treatments may be offered?
Treatment decisions depend on age, number and location of lesions, symptoms, skin type, medical history, and personal preference. A clinician may recommend no treatment, a prescription product, or an in-office procedure.
Prescription topical treatments: Some medicines are applied to lesions to trigger a local response or help remove them. They may cause redness, irritation, blistering, or discomfort. Use only products recommended for the specific person and body area. A treatment suitable for an arm may not be safe near the eyes or genitals.
In-office procedures: A healthcare professional may use methods such as freezing or carefully removing lesions. These can work, but may be uncomfortable and can leave temporary pigment changes or scars. Procedures may not be suitable for every child or every location.
Treatment of surrounding eczema: If the skin around the bumps is itchy and inflamed, treating the eczema may reduce scratching and discomfort. A clinician can advise on appropriate skin care.
There is no single best approach for everyone. Ask about the likely benefit, discomfort, risks of scarring or discoloration, and whether treatment is necessary at all.
What not to do
Avoid using over-the-counter wart removers, acids, essential oils, or home remedies unless a clinician specifically recommends them. These products can burn or irritate healthy skin, especially on a child’s face or in sensitive areas.
Do not:
Pop or squeeze bumps
Scrape them with a needle or blade
Apply harsh chemicals
Use another person’s prescription
Treat lesions close to the eyes or genitals without medical advice
If a treatment causes severe pain, blistering beyond the treated area, swelling, or signs of infection, stop using it and contact a healthcare professional.
When to Seek Medical Advice
Molluscum is usually mild, but an assessment can prevent confusion and help choose safe care.
Arrange a medical appointment if:
You’re unsure whether the bumps are molluscum
Lesions are near the eyes, on the eyelid, or affecting vision
Bumps are on or around the genitals
The rash is widespread, rapidly increasing, or unusually large
The person has a weakened immune system
The skin is very itchy, painful, or repeatedly breaking open
You notice increasing warmth, tenderness, pus, or spreading redness
The bumps persist and are causing distress or social difficulties
Seek prompt care for severe pain, fever with a worsening skin infection, or rapidly spreading redness. Those symptoms are not typical of uncomplicated molluscum.
A note about immune health
People with weakened immune systems may develop larger, more numerous, or harder-to-clear lesions. This can occur for different reasons, including certain medical conditions or treatments. A clinician can assess the skin and consider the person’s overall health rather than treating the bumps in isolation.
A note about emotional well-being
Visible skin conditions can be stressful, especially for children and teens. A child may worry that classmates will notice, or a parent may feel pressure to “get rid of” every bump quickly. Calm, matter-of-fact explanations help: molluscum is common, it is not caused by poor hygiene, and it usually goes away.
If a child is being teased or avoiding activities, tell the school or coach what practical steps are in place. A healthcare professional can also discuss whether treatment is worthwhile based on the child’s comfort—not just the appearance of the skin.
FAQs
- Is molluscum contagiosum dangerous?
Usually not. In healthy people, it is generally a mild skin infection that clears over time. Complications are uncommon, though scratching can lead to irritation, scarring, or a secondary skin infection.
- How long does molluscum contagiosum last?
It varies. Many cases clear within several months, while others last a year or longer. The bumps may disappear gradually rather than all at once.
- Can molluscum go away without treatment?
Yes. The immune system often clears it without medical treatment. A clinician may recommend waiting when lesions are mild and treatment could cause unnecessary discomfort or skin changes.
- Is molluscum contagious before bumps appear?
It may be possible to spread the virus before all lesions are noticed. Because bumps can be small and develop over time, it can be difficult to know exactly when exposure happened.
- Can my child go to school with molluscum?
Usually, yes. Follow school policies and cover lesions when practical, especially during close-contact activities. Keeping a child home until every bump disappears is generally not necessary.
- Can a child with molluscum go swimming?
Often, yes, but cover visible lesions with watertight bandages where possible and avoid sharing towels or swimwear. Check the pool’s policies and ask a clinician if lesions are open, irritated, or difficult to cover.
- Does molluscum spread through swimming pool water?
The water itself is not considered the only or necessarily main route. Close skin contact and shared towels, equipment, or other items may contribute to spread around swimming activities.
- Can adults get molluscum contagiosum?
Yes. Adults can get it through skin-to-skin contact, shared items, or intimate contact. Genital-area bumps should be assessed because other conditions can look similar.
- Is molluscum a sexually transmitted infection?
It can spread through intimate skin-to-skin contact, including sexual contact, but it also commonly spreads among children and through nonsexual contact. A clinician can help assess genital lesions and discuss appropriate next steps.
- Do condoms prevent molluscum?
Condoms can reduce contact with some affected skin but do not cover every area where lesions may be present. They cannot fully prevent transmission if bumps are on nearby uncovered skin.
- Can scratching spread molluscum?
Yes. Scratching or picking can move the virus to nearby areas or break the skin. Keep nails short, cover itchy lesions when practical, and ask a clinician about managing irritation.
- Should I pop or squeeze the bumps?
No. Popping or squeezing can cause pain, bleeding, scarring, infection, and spread to nearby skin. Leave removal or treatment decisions to a qualified healthcare professional.
- Can molluscum leave scars?
It can, particularly if bumps are picked, infected, or removed aggressively. Some treatments may also cause temporary discoloration or scarring, so discuss risks before proceeding.
- What does the dimple in the middle mean?
A central indentation is a common feature of molluscum lesions. It can help a clinician recognize the condition, but it does not confirm the diagnosis on its own.
- Why are the bumps turning red?
Redness can happen when the immune system begins responding to a lesion. However, increasing pain, warmth, pus, or spreading redness may indicate irritation or a secondary infection and should be assessed.
- Can molluscum be itchy?
Yes. Itching is common, especially when eczema develops around the bumps. Scratching can spread the virus, so seek advice about safe ways to ease the itch.
- Is molluscum caused by poor hygiene?
No. Molluscum contagiosum is caused by a virus and can affect anyone. It is not a sign that someone is dirty or has failed to wash properly.
- Can pets spread molluscum to people?
Human molluscum contagiosum is caused by a virus that spreads among people. It is not generally considered an infection passed from household pets.
- Can I use wart remover on molluscum?
Don’t use wart remover unless a healthcare professional specifically advises it. Some products can burn or damage the surrounding skin, especially on the face, in sensitive areas, or on children.
- Are home remedies safe?
Not necessarily. Acids, essential oils, and other home remedies can irritate or injure skin and may not clear the infection. Ask a clinician before applying anything beyond gentle skin care.
- Does every case need treatment?
No. Many cases can be monitored while the body clears the infection. Treatment may be considered if lesions are uncomfortable, spreading, in a sensitive location, or causing significant distress.
- Is treatment painful?
It depends on the method, the person’s age, and where the lesions are. Some procedures can sting or feel uncomfortable, and topical treatments may irritate the skin. Ask the clinician what to expect.
- Can treatment cause skin discoloration?
Yes. Some treatments and the lesions themselves can leave temporary lighter or darker marks. The risk can vary by treatment, skin type, and how the skin heals.
- Can molluscum come back after it clears?
A person may develop new lesions while an earlier infection is still resolving, or they may become infected again later. New bumps should be assessed if the diagnosis is uncertain.
- Can I shave over molluscum bumps?
It’s best to avoid shaving over affected skin. Shaving can irritate lesions and spread the virus to nearby areas. Ask a clinician about grooming around lesions in sensitive locations.
- Should I cover the bumps all the time?
Not necessarily. Covering can help during close-contact activities or when clothing may rub against the lesions. Use clean, breathable coverings and replace them if they become wet or dirty.
- Can molluscum affect the eyes?
Lesions can occur near the eyelid. Because treatment around the eye needs special care, contact a healthcare professional rather than applying over-the-counter products or trying to remove them yourself.
- When should genital bumps be checked?
Have new or unexplained genital-area bumps assessed, particularly if they are painful, changing, or accompanied by other symptoms. Molluscum can resemble other conditions that require different evaluation and care.
- Is molluscum more serious for someone with a weakened immune system?
It can be more extensive or persistent in people with weakened immune systems. They should seek medical advice for diagnosis and a treatment plan suited to their health.
- What is the best first step if I think I have molluscum?
Avoid picking or treating the bumps with harsh products. Arrange an assessment if you’re unsure, the lesions are in a sensitive area, or symptoms are worsening. If the diagnosis is clear and the bumps are mild, a clinician can help you decide whether monitoring is appropriate.
Conclusion: Calm, Practical Care Goes a Long Way
Molluscum contagiosum can be frustrating because the bumps are visible and may take time to disappear. But for most healthy people, it is a manageable skin infection that clears on its own. Protect irritated skin, avoid picking, don’t share personal items, and get medical advice when the diagnosis or location raises questions.
If you or your child has unexplained bumps, a healthcare professional can confirm what they are and help you choose between watchful waiting and treatment. The best plan is the one that protects the skin, fits the person’s situation, and avoids unnecessary distress.
