Molluscum contagiosum (MC) is a viral infection that causes harmless spots. It usually spreads through skin-to-skin contact. It mostly affects children, but in adults it can often be passed on through sex. MC can also spread if you share personal items such as towels, but it is not a sign of bad hygiene.

The main symptom of MC is raised spots, which can be confused with other rashes such as chicken pox. If you are unsure what is causing your spots check with your GP. 

Spots caused by MC can:

  • Form in clusters and each spot usually measures no more than half a cm wide. They are bumpy, domed and have a pale dimple in the middle. 
  • Appear almost anywhere on your body. If the infection has spread through sex the spots will often crop up around the lower tummy, genitals and thighs. They can appear on your face and eyes if you have a weakened immune system, for example if you’re being treated for cancer.

You get MC through skin-to-skin contact with someone who has the virus. In adults this most often happens during sex. 

MC usually clears up on its own within 18 months. It rarely needs treatment. There are some self-care tips you can try if it feels itchy: 

  • Press a damp towel to your skin.
  • Have a cool bath.
  • Use plenty of fragrance free emollient (moisturising) cream.

Try not to scratch your spots. This will stop them getting infected.

If you are diagnosed with MC at a clinic appointment we may offer to freeze off your spots or use a liquid treatment on them.

You do not need to see a GP unless: 

  • Your spots become very itchy, painful or crusty.
  • There are spots near your eyes or eyelids.
  • You have a weakened immune system for any reason.
  • Your symptoms are not going away and you have had MC for 18 months or more. 

Your GP may prescribe antibiotics or steroid creams, or refer you to a specialist doctor. 

We know that having spots for a fairly long time can make you feel fed up or self-conscious. It might feel extra tough if your spots are on your genitals and you are worried about explaining them to your sexual partner or partners. Please try to keep in mind that MC can happen to anyone. It does not say anything about you. You can always call us on 0800 328 3383 if you feel you could do with more support. 

If you know someone has MC, do not share baths or items such as duvets and towels with them. 

If you have MC: 

  • Keep the areas where you have spots covered as much as you can.
  • Buy special waterproof bandages if you want to go swimming. 
  • Use a condom while having sex.
