Molluscum contagiosum

Also called Water warts

Molluscum contagiosum is a viral skin infection that causes small, firm, raised spots, often with a dimple in the middle. It is common in children, but adults can get it too. It spreads through close contact, shared towels and baths. It is harmless and usually goes away on its own, but this can take up to 18 months or longer.

What it is

Treatment is not usually needed. Not scratching or squeezing the spots and not sharing towels help stop it spreading.

Treatments such as freezing are sometimes offered to adults or if the spots are bothersome.

Common signs

  • Small, firm, raised spots
  • A dimple in the centre of each spot
  • Spots that are skin-coloured, pink or white
  • Mild itching or redness around the spots

How it is usually diagnosed

  • Examination of the skin

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Notes on the spots and any treatment

Questions to ask your doctor

  • Does it need treatment?
  • Can my child still go swimming?
  • How can we stop it spreading?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Spots near the eye with a red or sore eye: get it checked soon
