Adenovirus Infection Management in Children

General Principles

The American Academy of Pediatrics recommends supportive care with hydration, antipyretics, and respiratory support as needed for immunocompetent children with adenovirus infection, while cidofovir is reserved for life-threatening infections in severely ill or immunocompromised children 1
Supportive care is the cornerstone of management for the vast majority of children with adenovirus infection, with the infection typically resolving within 7-10 days without specific antiviral therapy 1

Adequate hydration is essential to maintain fluid balance in children with adenovirus infection 1
Antipyretics are recommended for fever management in children with adenovirus infection 1
Respiratory support, such as oxygen and nebulizers, may be necessary for children with adenovirus infection 1
Monitoring for clinical deterioration is crucial over the typical 7-10 day illness course 1

Patients with adenovirus infection are infectious for 10-14 days from symptom onset 1, 2
Hand hygiene with soap and water is essential for preventing the spread of adenovirus infection 1
Dilute bleach solution is recommended for equipment and surface disinfection to prevent the spread of adenovirus infection 1
Isolation in hospitals and daycare settings is necessary to prevent outbreaks of adenovirus infection 1

The American Academy of Ophthalmology recommends symptomatic relief, such as artificial tears and topical antihistamines, for adenoviral conjunctivitis 2, 3, 4
Topical corticosteroids may be indicated for severe cases of adenoviral conjunctivitis with marked chemosis, lid swelling, epithelial sloughing, or membranous conjunctivitis 2, 3, 4

Cidofovir is the treatment of choice for severe adenovirus infections, particularly in immunocompromised children or those with disseminated disease 1
The standard regimen for cidofovir is 5 mg/kg IV once weekly for 2 weeks, then every other week 1
Mandatory renal function monitoring is essential due to the considerable nephrotoxicity risk associated with cidofovir 1

Adenovirus serotypes 3 and 7 have a worse prognosis 1
Age under 1 year with myocarditis is associated with a 5-year survival rate of only 66% with adenovirus versus 95% without 1
Immunocompromised status is associated with fatality rates exceeding 50% for untreated severe pneumonia or disseminated disease 1
