- Picked up via close personal contact incubation period of a few weeks
- There are small pearly topped papules with a central depression (punctum).
- Usually 2-6 mm across but can be larger than this, up to 10 to 20 mm
- Koebner phenomenon is seen where the lesions appear along with sites of trauma
- Widespread Molluscum especially on the face of an adult should raise the question of HIV infection
- More common and extensive in people who have atopic eczema
- Skin biopsy needed rarely
- HIV test in selected patients
- Usually goes away by itself, taking between 6 and 18 months to do so. Otherwise, treatment is usually to stimulate an inflammatory response through direct trauma or cryotherapy.
- In HIV positive patients they usually resolve on the initiation of HAART
- Liquid nitrogen (cryotherapy) by the general practitioner or dermatologist at intervals until they are clear.
- Spots can be scraped off with a sharp instrument (curettage) after local anaesthetic injection by the general practitioner or dermatologist.
- Eye specialist can deal with spots on the eyelids.
- Imiquimod has been used for molluscum contagiosum, but it is not licensed for the condition and most research studies have shown that it is not effective.

- However children with Molluscum contagiosum need not be kept off school, nor should they be barred from swimming, etc.
