Ringworm is a common and highly infectious skin infection that causes a ring-like red rash on the skin.
The rash can appear almost anywhere on the body, with the scalp, feet and groin being common sites.
The condition, medically known as "tinea", isn't serious and is usually easily treated using creams sold by the pharmacy. However, ringworm is highly contagious and easily spread among people.
Despite its name, it doesn't have anything to do with worms. It's an infection of the skin caused by a fungus.
When to see a doctor
You need to see your GP if you or your child have ringworm of the scalp. This type of ringworm is treated with antifungal tablets only available on prescription.
Other types of ringworm are generally treated with antifungal cream from the pharmacy and you don't need to see a doctor unless the infection persists. However, pharmacists often prefer children to see a GP to confirm a diagnosis.

Who is affected?
Ringworm is common. It's estimated that 10-20% of people will have a fungal skin infection at some point during their lifetime.
People of all ages can be affected by ringworm, but children are particularly susceptible to it.
Scalp ringworm (tinea capitis) is most common in children who have not reached puberty (sexual maturity), particularly those who live in urban areas and African-Caribbean children.
Body ringworm can affect anyone of any age, although groin infections are more common in young men.
Most cases of ringworm are mild and can be treated using a pharmacy antifungal cream.
Scalp ringworm can be treated with antifungal tablets, sometimes combined with antifungal shampoo.
Sometimes, if ringworm leaves the skin irritated or broken it can lead to other bacterial infections, which may need treatment with antibiotics.

Stopping it spreading
It's really important, where possible, to prevent spreading the infection. You should avoid sharing towels, bedding or clothes with anyone diagnosed with ringworm.
If you think your pet has ringworm, take it to the vet. If your pet is treated quickly, you will be less likely to catch the infection from it.
If your child has ringworm, they do not need to stay off school. However, you should inform the school your child has the condition. In addition to treatment, your child should maintain a good level of personal hygiene to prevent the infection spreading.
