[Fever of unknown origin in a young child: diagnosis and treatment]

Area of Science:

• Pediatrics
• Infectious Diseases
• Clinical Diagnostics

Context:

• Fever without a focus in children presents diagnostic challenges, especially in young infants who may not exhibit typical infection symptoms.
• Early recognition of serious bacterial infections (SBIs) and bacteremia is critical in febrile children.
• Age-specific clinical signs are vital for assessing risk in children aged 1 to 36 months.

Purpose:

• To outline an evidence-based approach for evaluating children with fever without a focus.
• To guide clinicians in identifying children at increased risk for bacteremia or major bacterial infections.
• To differentiate between children requiring hospitalization and those suitable for outpatient management.

Summary:

• Infants under 1 month with fever or hypothermia require immediate clinical evaluation and diagnostics.
• Children aged 1-36 months with concerning clinical signs (toxic appearance, high fever, diarrhea, tachypnea, etc.) necessitate hospital admission and parenteral antibiotics.
• Febrile children without alarming clinical signs and with normal lab results can be managed as outpatients with parental guidance.

Impact:

• Facilitates appropriate and timely management of febrile children, reducing risks associated with SBIs.
• Empowers healthcare providers with clear diagnostic criteria for febrile illnesses in pediatric populations.
• Enhances patient safety through structured evaluation protocols and parental education for early detection of clinical deterioration.
