When should I contact a doctor if my child has a rash?

You should contact a doctor if:

  • The rash is widespread or the child seems affected.
  • The rash does not go away after a few days or gets worse.
  • The child has fever, vomiting, diarrhea or other serious symptoms.
  • You are unsure of the cause of the rash.

Examination for rash

The doctor who examines the child will ask a number of questions about the rash, when it occurred, how the child seems affected, whether there are others in the circle of friends who have something similar, whether the child has been vaccinated etc.

The doctor will then take a thorough look at the skin, possibly taking a brush test to test for bacteria, fungi and viruses if you are unsure.

If the child is in bad shape, the temperature is usually checked and a small blood sample is taken (small prick in the finger) to check the level of infection in the body.
