Rashes in babies and children

Many things can cause a rash in children, and they're often nothing to worry about.

Go to A&E or call 999 if your child has a rash and they:

  • have a stiff neck
  • are bothered by light
  • seem confused
  • are shaking uncontrollably
  • have a fever you can't control
  • have unusually cold hands and feet
  • have a rash that doesn't fade when you press a glass against it

These can be signs of meningitis.

See a GP if:

  • your child seems unwell, and has a rash and a fever

Use the information on this page to get an idea of what to do about a rash. But don't self-diagnose – see a GP if you're worried.

Rash with fever

Fever and red cheeks

Bright red spots on childs cheeks


A fever and a bright-red rash on both cheeks can be slapped cheek syndrome. Your child may have a cold, and the rash can spread to the body.

It usually clears up within a week. Children's paracetamol can bring down a fever.

Blisters on hands, feet and in the mouth

Hand, foot and mouth disease is a common childhood illness that causes blisters on the hands and feet, and ulcers on the tongue. It also causes fever, and your child may have a cold.

It usually clears up in about a week. Children's paracetamol can bring down a fever.

Pink-red rash

Scarlet fever rash on a child


Scarlet fever causes a pink-red rash, which feels like sandpaper and looks like sunburn.

It usually starts with a swollen tongue, sore throat, headache and fever.

See your GP straight away if you suspect scarlet fever. It's treated with antibiotics.


Measles rash on a child


Measles usually starts with a fever, sore eyes that are sensitive to light and grey spots inside the cheeks.

After a few days, a red-brown rash appears on the head or neck and spreads to the rest of the body.

Call your GP if you think you or your child has measles.

Rash with itching

Heat rash should clear up without treatment.

Scaly red skin or cracked skin

Eczema on the knees


Skin that's itchy, red, dry and cracked may be eczema. It's common behind the knees, elbows and neck, but it can appear anywhere.

Speak to your GP if you think your child has eczema.

A raised, itchy red rash (hives) can appear as an allergic reaction to things like stings, medicines or food.

It usually clears up within a day or two.

Speak to your GP if your child keeps getting this type of rash. They may be allergic to something.

Call 999 if there's swelling around their mouth.

Ask your pharmacist for a cream or lotion to treat ringworm.

Speak to your GP if it appears on your child's scalp, as it may need to be treated with medicine.

Small spots and blisters

Chickenpox causes red spots that turn to blisters. They can be itchy. They eventually scab and fall off.

Some children have a few spots, while others have them all over their body.

Itchy red sores or blisters

Red sores or blisters that burst and leave crusty, golden-brown patches could be impetigo.

The sores or blisters can be itchy, get bigger or spread to other parts of the body. They often appear on the face, hands or around the middle of the body.

Speak to your GP if your child may have impetigo.
