What is a Molluscum Contagiosum Skin Infection?
Molluscum contagiosum is a common viral skin condition caused by a poxvirus. It leads to a molluscum contagiosum skin infection, which appears as either red/pink or raised skin coloured bumps. These bumps are usually dome-shaped and firm, often with a central dimple. They tend to measure 2–5 mm across but can sometimes grow larger.
The virus is passed through direct skin contact or by sharing contaminated items such as towels or clothing. While it is not serious, a molluscum contagiosum infection can take 12–18 months to clear without treatment. In some cases, people may seek molluscum contagiosum skin infection treatment to speed up recovery or reduce the risk of spreading the virus.

The main symptom of molluscum contagiosum infection is raised skin-coloured bumps. These may appear pink or red, especially if inflamed or irritated. A typical presentation includes small clusters, often forming after scratching. In some cases, eczema-like patches can develop around the bumps.
Spots commonly appear on the face, chest, armpits, groin and upper thighs. Most people develop fewer than 30 bumps, but in some cases, more extensive breakouts may occur.
How is Molluscum Contagiosum Spread?
Molluscum contagiosum is mainly spread through skin-to-skin contact. However, you can also catch molluscum contagiosum by sharing contaminated objects like towels, bedding or bathwater. Scratching can spread the virus to other parts of the body.
Adults often have immunity due to childhood exposure. Still, children in close contact can easily pass it between themselves. In adults, molluscum contagiosum can sometimes be transmitted sexually, causing bumps in the genital area and lower abdomen. If this occurs, a full check-up at a sexual health clinic is recommended.
How Long Does Molluscum Contagiosum Last?
Each bump typically lasts for a few weeks to months before it disappears. However, new ones often appear as old ones fade. This cycle can continue for over a year. Most cases resolve within 12–18 months, but some infections can persist for up to five years.
If you develop hundreds of lesions or unusually large spots, it may indicate a weakened immune system. In such cases, further medical evaluation is advised.
Can Molluscum Contagiosum Be Prevented?
The chance of passing on the molluscum contagiosum virus to others is small. However, you can reduce the risk of transmission by following these tips:
- Avoid sharing towels, soft toys, clothing and bathwater.
- Don’t scratch the affected areas.
- Avoid shaving over infected skin.
There’s no need to keep children away from school or swimming. Likewise, adults can continue to attend gyms and still take part in social activities.
Molluscum Contagiosum Skin Infection Treatment & Advice
In most children, molluscum contagiosum treatment isn’t necessary. It’s a harmless, self-resolving condition. However, if treatment is required—such as for cosmetic reasons or in adults—several options are available.
Common molluscum contagiosum skin infection treatments in Sussex with Laser & Skin Clinics include:
- Topical solutions, such as potassium hydroxide (e.g. Molludab).
- Cryotherapy, where bumps are frozen with liquid nitrogen.
- Curettage, which involves scraping off the bumps under local anaesthetic.
No single treatment has proven superior. Treatment choice depends on age, comfort level and severity of the condition.
