If your child is very young, has a high temperature or isn’t eating and drinking, take them to see your family doctor (GP). Some rashes, such as cellulitis and impetigo, are caused by a bacterial infection and need to be treated with antibiotics.
It's also best to see your GP if your child’s rash hasn’t disappeared within a few days, or if you think it’s getting worse. If your medical centre is closed, you can phone the government’s free 24/7 health advice line, Healthline, on 0800 611 116 for advice from a registered nurse.
Highly infectious diseases such as measles and chickenpox also cause a rash. If you think your child has either of these it’s best to see your GP.
Rashes caused by chronic conditions such as eczema, psoriasis or allergies need ongoing support and treatment, which is also best managed by your GP.
