About this information

NICE clinical guidelines advise the NHS on caring for people with specific conditions or diseases and the treatments they should receive. The information applies to people using the NHS in England and Wales.

This information explains the advice about fever in children that is set out in NICE clinical guideline 160.

All of the treatment and care that NICE recommends is in line with the NHS Constitution (www.gov.uk/government/publications/the-nhs-constitution-for-england). For more information see 'About care in the NHS' on our website (www.nice.org.uk/nhscare).
