Rashes

Skin rashes are common in babies and children.

Most rashes are harmless and go away on their own.
The causes of skin rashes tend to differ in babies compared to older children. Many viruses can cause a rash in addition to other symptoms such as fever and cough. The rash often varies in shape and size, usually appearing as blotchy red spots commonly affecting most of the body. They sometimes appear quite quickly and usually last for only a few days. These rashes are generally ‘non-specific’, which means that it is often hard to say which specific virus is the cause.

You can get general advice on the NHS Conditions or from your local pharmacy

Some rashes require no medical input and simply get better by themselves without any treatment. This includes viral rashes. If your child has a fever, you may want to lower their temperature using paracetamol (Calpol) and/or ibuprofen.
Some rashes require you to keep your child off from nursery or school. This includes chickenpox and scarlet fever.
However, certain conditions such as eczema and impetigo may require treatment from your GP.

If it is non-urgent, speak to your local pharmacist or health visitor.
Or contact you GP practice and a qualified member of the clinical team will assess if your child needs to be seen urgently. For an urgent out-of-hours GP appointment, call NHS 11 1.
You should only call 999 or go your nearest A&E department in critical or life threatening situations.
