Molluscum contagiousum (molluscum for short) is a skin infection that is common in tamariki. It causes small raised bumps that can appear anywhere on the body. Molluscum spreads easily around the body and between people. It is caused by a virus.
Molluscum mainly affects young tamariki under the age of 10 years. Rangatahi (young people) can also get molluscum, but it is not as common.
Most adults have been exposed to molluscum when young. That means they're protected against it. Parents are unlikely to become infected after touching their child's molluscum.

Molluscum can show up anywhere on the body. But the bumps often appear in warm, moist places such as:
Molluscum doesn’t happen on the palms or soles. Molluscum is not painful but can be itchy.
Molluscum can spread easily to other places on your child's body and to other people.
Molluscum can spread around the body when tamariki touch the infected area and then touch another part of their body.
Common ways it can spread to others include:
Because molluscum spreads easily, good hygiene is important. This will help reduce the chance of it spreading between tamariki.
Try the following tips if your child has molluscum.
Wash and dry your hands well after touching your child’s skin with molluscum.
If your child has plasters covering the molluscum, throw them away carefully.
Don’t share towels or clothing.
Dry the skin with molluscum bumps last. The virus can spread when drying with a towel.
It’s best for your child to have showers instead of baths if possible. The molluscum virus can spread in bathwater.
Make sure your child doesn’t share baths with other tamariki.
Don’t use bath toys. Or, if you do, make sure to clean and dry them after using them.
If you think your child may have molluscum, it’s a good idea to see your doctor. It may be helpful to take some photos of your child's skin with you when having a health check.
Most tamariki won't need any treatment for molluscum. The bumps normally clear up on their own. Molluscum usually clears up 6 to 18 months after it appears.
Tamariki may need treatment if they have bumps on and around their face, especially if the bumps are worrying them.
Tamariki with low infection-fighting ability (low immunity) may need treatment. The virus can take longer to clear for them.
For tamariki with both eczema and molluscum, it's important to focus on good eczema management before looking at options to treat the molluscum.
There are several different treatments for molluscum, but none of the options are totally effective. If your child needs treatment, your child’s doctor will discuss the best option with you.
The doctor may recommend your child puts a cream, lotion or ointment on their bumps. There are several different options, and some can irritate the skin around the bumps. Your child's doctor will talk you through how to use these safely.
Some doctors may recommend freezing the bump with liquid nitrogen. This can be quite uncomfortable. Doctors don’t usually recommend this if your child has lots of molluscum all over their body. Liquid nitrogen may leave a white spot on the skin where the molluscum used to be.
Other treatments include:
Some of these treatments can lead to scarring once the molluscum has gone.
If molluscum bumps are scratched or bumped, they may become infected with a bacterial infection. If the skin around the molluscum becomes red and irritated, take your child to the doctor. They may need some antibiotics to treat the infection. Antibiotics will not get rid of the molluscum bumps but can help clear the infection around them.
Some tamariki may be left with scarring after the molluscum clears up. This can happen with or without treatment, but some treatment options may make scarring more likely. Scratching or irritating the molluscum often may also lead to scarring.
Tamariki don’t need to take time off school or activities.
Molluscum can take months to years to clear up. Tamariki with molluscum are usually otherwise healthy.
