Ringworm

Also called Tinea, Tinea corporis, or Scalp ringworm

Ringworm is a common fungal infection of the skin. It often causes a ring-shaped rash that may be red, silver or darker than the surrounding skin, and itchy. It can appear anywhere, including the scalp and groin. It spreads easily through skin contact, from pets such as cats and dogs, or from towels and bedding.

What it is

It is usually treated with antifungal creams. Scalp ringworm needs antifungal tablets and shampoo.

Washing hands, not sharing towels and treating pets help stop it spreading.

Common signs

  • A ring-shaped rash
  • Itchy skin
  • Scaly, dry or swollen patches
  • Patches of hair loss on the scalp
  • Rash that slowly gets bigger

How it is usually diagnosed

  • Looking at the rash
  • Sometimes a skin scraping or hair sample

Records worth keeping

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

  • GP notes
  • Skin or hair test results
  • Prescriptions

Questions to ask your doctor

  • How long should I use the treatment?
  • Should my pet be checked?
  • Can my child go to school?

When to get help right away

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

  • A rash that spreads quickly with pain, pus or a high temperature: see a doctor the same day
