What is the approach to managing fever and cough in an unimmunized child?

Management of Fever and Cough in an Unimmunized Child

Unimmunized children with fever and cough require a structured approach based on severity of symptoms, with low threshold for antibiotic therapy and careful monitoring for complications due to their higher risk of vaccine-preventable infections. 1

Initial Assessment and Triage

Mild Cases (Treat at Home)

• Children with mild cough and low-grade fever should be managed at home with antipyretics and adequate fluid intake 1
• Acetaminophen or ibuprofen should be used for fever control (Note: aspirin should NOT be used in children under 16 years of age due to risk of Reye's syndrome) 1

Moderate Cases (Community Health Professional Assessment)

• Children with high fever (>38.5°C) and cough should be evaluated by a healthcare professional 1
• Children under 7 years of age should be seen by a nurse or doctor 1
• Children under 1 year of age should always be evaluated by a physician due to higher risk of complications 1

High-Risk Cases (GP or Emergency Department Assessment)

• Children with high fever (>38.5°C) AND any of the following require physician evaluation: 1
  • Breathing difficulties
  • Severe earache
  • Vomiting >24 hours
  • Drowsiness
  • Any chronic comorbid disease

Treatment Approach

For Mild-Moderate Cases

• Provide antipyretics (acetaminophen or ibuprofen) and ensure adequate hydration 1
• In unimmunized children, maintain a lower threshold for antibiotic therapy compared to immunized children due to higher risk of bacterial infections 1
• For children over 1 year with influenza-like symptoms, consider antiviral therapy (oseltamivir) if within 48 hours of symptom onset 1

For High-Risk Cases

• Offer antibiotics plus antipyretics and adequate fluid intake 1
• For children over 1 year with influenza-like symptoms, add oseltamivir 1
• Consider empiric antibiotic therapy based on likely pathogens: 1
  • For suspected pneumococcal infection: Amoxicillin 90 mg/kg/day divided TID
  • For suspected H. influenzae: Amoxicillin-clavulanate or cefuroxime
  • For suspected atypical pneumonia: Add azithromycin (10 mg/kg on day 1, then 5 mg/kg on days 2-5) 2

Indications for Hospital Admission

Refer for hospital assessment if ANY of the following are present: 1

• Signs of respiratory distress:
  • Markedly raised respiratory rate
  • Grunting
  • Intercostal recession
  • Breathlessness with chest signs
• Cyanosis
• Severe dehydration
• Altered level of consciousness
• Complicated or prolonged seizure
• Signs of septicemia (extreme pallor, hypotension, floppy infant)

Hospital Management

• Most children admitted to hospital will need: 1
  • Oxygen therapy if saturation <92%
  • Intravenous fluids if unable to maintain hydration
  • Antibiotics (intravenous if severely ill)
  • Antiviral therapy if influenza suspected

Indications for ICU/HDU Transfer

Transfer to high dependency or intensive care if: 1

• Failing to maintain oxygen saturation >92% despite supplemental oxygen (FiO2 >60%)
• Shock
• Severe respiratory distress with elevated PaCO2 (>6.5 kPa)
• Rising respiratory and pulse rates with clinical evidence of severe respiratory distress
• Recurrent apnea or irregular breathing
• Evidence of encephalopathy

Special Considerations for Unimmunized Children

• Unimmunized children are at higher risk for vaccine-preventable infections including pertussis, pneumococcal disease, and Haemophilus influenzae type b 3
• Maintain a lower threshold for diagnostic testing and empiric antibiotic therapy 3
• Consider broader antibiotic coverage to include these pathogens 1
• Closer follow-up is essential, with clear return precautions given to caregivers 1

Diagnostic Approach in Hospital Setting

• Complete blood count with differential 1
• Blood cultures in moderate to severe cases 1
• Chest X-ray for children with respiratory distress or hypoxia 1
• Consider specific testing for pertussis in unimmunized children with paroxysmal cough 1
• Respiratory viral panel testing if available 1

Common Pitfalls to Avoid

• Delaying antibiotics in unimmunized children with high fever - they have higher risk of bacterial infections 3
• Failing to consider pertussis in unimmunized children with persistent cough 1
• Discharging without clear follow-up plans and return precautions 1
• Using aspirin for fever control in children (risk of Reye's syndrome) 1
• Underestimating severity in children with subtle signs of respiratory distress 1
