Molluscum contagiosum

Molluscum contagiosum is a common viral skin infection. It causes small firm skin coloured bumps anywhere on the body. While anyone can get it, it mainly affects tamariki (children) under 10 years old. It is harmless but can be passed on to other people.


How molluscum contagiosum spreads

Molluscum is spread by close skin-to-skin contact with someone with spots.

It can also be passed on by  sharing clothing or towels.

Molluscum can sometimes be passed on during sex.

You  can spread  molluscum from one part of the body to another by scratching.

Spots usually appear 2 weeks after you are infected but it can be several months later. 

You are more likely to get infected if you have a weakened immune system.  


Symptoms of molluscum contagiosum

Molluscum contagiosum causes groups of small, hard, skin-coloured, raised spots (like tiny domes) on the skin. These spots are around 2 to 6mm in size.

They can look shiny and waxy with a small central pore. They are normally painless but can be itchy or sore if they become inflamed.

The spots can be on any part of the body. But they are most commonly found in the armpit, behind the knee, or in the groin.


Diagnosising molluscum contagiosum

Molluscum  contagiosum is diagnosed from its appearance.

Dermnet has images of molluscum in adults and tamariki.  

If the skin around the lumps is red , get checked by your healthcare provider . You can get dermatitis or infection around the molluscum.

Treating molluscum contagiosum

The spots generally go away on their own. This can take from 6 months to 2 years.

If spots are causing a problem  they may be  removed by freezing, needling  or applying wart treatments.

If the skin around the molluscum gets inflamed or there is infection you may need a cream or antibiotic.
