Many childhood illnesses may cause a rash.  Many of them are viral and therefore have no treatment.  For the treatment of allergic rashes (nettle rash) please see the self help section on insect bites and stings.

A rash in a child who is otherwise well is not usually a cause for concern.


Rashes are often associated with temperature.  Cooling a child will often cause the rash to go away.


The rash associated with meningitis is a purplish blotchy rash which doesn’t fade when a glass is pressed against it.  By the time the rash appears the child is usually very obviously ill and you should telephone 999 immediately.


Contact the doctor when the surgery is open if:

  • rash persists and the child is unwell

Contact the doctor straight away if:

  • the rash is a purplish blotchy rash which doesn’t fade when a glass is pressed against it.
