This guideline covers the assessment and early management of fever with no obvious cause in children aged under 5. It aims to improve clinical assessment and help healthcare professionals diagnose serious illness among young children who present with fever in primary and secondary care.
This guideline should be read in conjunction with NICE’s guidance on sepsis, neonatal infection, meningitis (bacterial) and meningococcal septicaemia in under 16s, urinary tract infection in under 16s, diarrhoea and vomiting caused by gastroenteritis in under 5s and antimicrobial prescribing for common infections.
Feverish illness in young children usually indicates an underlying infection and is a cause of concern for parents and carers. Feverish illness is very common in young children, with between 20 and 40% of parents reporting such an illness each year. As a result, fever is probably the commonest reason for a child to be taken to the doctor. Feverish illness is also the second most common reason for a child being admitted to hospital. Despite advances in healthcare, infections remain the leading cause of death in children under the age of 5 years.
