Prevention and Treatment of Respiratory Infections in Children

Prevention: Vaccination-Based Strategy

The American Academy of Pediatrics recommends that all children receive conjugate vaccines against Streptococcus pneumoniae, Haemophilus influenzae type b, and pertussis as part of the routine childhood immunization schedule 1, 2, 3, 4
These vaccines prevent approximately half of pneumonia-related deaths worldwide in children under 5 years old 1
The 13-valent pneumococcal conjugate vaccine (PCV13) has been shown to reduce complicated pneumonia and empyema 1
The Centers for Disease Control and Prevention (CDC) recommends annual influenza vaccination for all infants ≥6 months, children, and adolescents 1, 2, 3, 4
The average efficacy of the trivalent inactivated influenza vaccine is 86% 1
The live attenuated influenza vaccine provides greater efficacy in children 6-59 months compared to the inactivated vaccine 1
Influenza vaccination also reduces secondary pneumococcal pneumonia, which is especially important given that bacterial pneumonia often complicates influenza infection 1, 2, 3

The American Academy of Pediatrics recommends that amoxicillin be used as first-line therapy for previously healthy, appropriately immunized infants and preschoolers with mild to moderate pneumonia of probable bacterial origin 7
Amoxicillin provides adequate coverage for Streptococcus pneumoniae, the most prominent invasive bacterial pathogen 7
For school-aged children and adolescents, consider atypical pathogens (Mycoplasma pneumoniae) in management decisions 7
Macrolide antibiotics should be prescribed for children (primarily school-aged and adolescents) evaluated in the outpatient setting with findings compatible with atypical pneumonia 7
In children ≥5 years, macrolides may be used as empirical first-line treatment since Mycoplasma pneumoniae is more prevalent in this age group 8

The American Thoracic Society recommends that patients with oxygen saturation ≤92% breathing room air be treated with oxygen to maintain saturation >92% 8
Maintain oxygen saturation >90% using supplemental oxygen as needed 5, 6
Patients on oxygen therapy should have observations at least every 4 hours, including oxygen saturation 8, 5
Ensure adequate hydration through oral fluids if tolerated, or via nasogastric or intravenous routes if the infant cannot maintain oral intake 5
Intravenous fluids, if needed, should be administered at 80% of baseline levels, and serum electrolytes should be monitored 8

The American Academy of Pediatrics recommends hospitalization for infants with oxygen saturation <92%, cyanosis, respiratory rate >70 breaths/minute, difficulty breathing, apnea, or poor feeding 8
For older children, hospitalization is recommended for those with oxygen saturation <92%, cyanosis, respiratory rate >50 breaths/minute, difficulty breathing, or signs of dehydration 8

The child being cared for at home should be reviewed by a physician if they deteriorate or do not improve after 48 hours of treatment 8
If a child remains febrile or ill 48 hours after admission with pneumonia, reevaluation is necessary, considering possible complications 8
Children who receive adequate therapy should demonstrate clinical improvement within 48-72 hours, including decreased fever, improved respiratory rate, decreased work of breathing, stable oxygen saturation, and ability to maintain adequate oral intake 5
