Molluscum is a common viral skin infection that causes small, harmless, raised spots to appear on the skin. It is caused by the molluscum contagiosum virus. Once infected, your child can easily spread molluscum to other people, or to different areas on their own body. It is spread by touching the molluscum spots, and through bath or pool water, bath toys and towels.
Molluscum spots may stay on the body for a few weeks, several months or more than a year. Molluscum does not usually need any treatment.
At first, molluscum spots look like white pimples. They then become round, pearl-coloured lumps that have a white mark or indentation in the centre. They are usually 1–5 mm in size, but can be as big as 2 cm. Generally, molluscum spots are found on the stomach, face, arms, legs or in the nappy area.
Molluscum spots are painless and usually not itchy.
The molluscum virus is found in warm water, so children are often infected in swimming pools and baths. Sharing towels and face washers is another way to spread the virus. Molluscum can also be spread from skin-to-skin contact involving the molluscum spots.
It can take weeks or even months for the spots to appear after your child has come into contact with the molluscum virus.
Good personal hygiene is important to help prevent molluscum spreading. If your child has molluscum:
Most adults have been exposed to molluscum in their youth and are therefore immune, so it is not likely you will become infected by touching your child's spots.
Most of the time, molluscum does not need any treatment. The spots usually disappear over time as the body fights and kills the virus. In some children this can take more than a year. Molluscum spots heal without scarring.
There are a number of treatment options that aim to speed up the body’s natural process of fighting the molluscum virus. These are designed to irritate the molluscum spots, causing them to become red and inflamed. This activates the body’s immune system, helping it to fight the molluscum virus. Some treatment options include:
The treatment may also irritate the surrounding skin, and more aggressive treatment may cause scarring. If the spots are not causing symptoms and are hidden under clothing, it is better to wait for body’s natural immune system to work, without any specific treatment. If the spots are causing problems, consult a GP, dermatologist or dermatology nurse practitioner to explore treatment options.
If your child is experiencing both eczema and molluscum, the eczema needs to be treated before any treatment for molluscum can take place.
Sometimes, the skin around the molluscum spots can develop a rash and the skin can become infected with bacteria. If this happens, take your child to a GP. Antibiotics may be prescribed for the skin infection, but the antibiotics do not treat the molluscum spots themselves, because antibiotics do not work against viruses.
Why does my child scratch at their molluscum?
Molluscum spots usually don’t itch. It's more likely that the molluscum has caused a local flare up of pre-existing eczema, which may be itchy.
Can my child go to child care if she has molluscum?
Children with molluscum can go to school, child care and kindergarten, and play with other children, because clothing usually covers the affected areas.
