They are harmless small papules or bumps on the skin caused by a viral infection (a pox virus).
The infection is passed on by direct skin-to-skin contact and may affect any part of the body.
Sexual contact may lead to papules in the genital area.
They may appear on the face of people infected with HIV.
In most people they will usually go away by themselves after several months.
They may be treated with cryotherapy (liquid nitrogen spray).
If you have Molluscum contagiosum we recommend an STI screen and HIV test.
How common are Molluscum contagiosum?
In adults infection in the genital area is common.
Infection is more common in people who are immunosuppressed e.g. HIV, organ transplant, on chemotherapy.

Small, smooth, pearly bumps or papules usually 2-4mm in diameter, with a dimple in the middle.
How do I get tested for Molluscum contagiosum?
An experienced clinician can confirm the diagnosis on visual examination.
How are Molluscum contagiosum treated?
Although in non – immunosuppressed people the papules will eventually clear spontaneously, most people prefer to have treatment to clear them up more quickly.
Treatment with cryotherapy (liquid nitrogen) is provided in the clinic.
Most people will only need one or two treatments.
Sometimes a cream treatment is recommended.
What about my partner?
Your partner should be checked for molluscum too.
What problems can untreated Molluscum contagiosum lead to?
Sometimes scratching may lead to a secondary bacterial infection of the skin – it looks red and may feel sore, and you may need treatment with antibiotics.
Will Molluscum contagiosum come back again after treatment?
Not normally unless the papules were only partially treated or you have been re-infected.
