Management of Adenovirus in Children

Treatment Approach

The American Academy of Pediatrics recommends supportive care only, including hydration, antipyretics, and respiratory support as needed, for immunocompetent children with mild-moderate disease 1, 2
The Centers for Disease Control and Prevention suggests that no specific antiviral therapy is indicated for self-limited gastroenteritis or upper respiratory infections 3, 1
The American Academy of Pediatrics advises monitoring for clinical deterioration over 7-10 days, which is the typical illness duration 1
Cidofovir is the treatment of choice for life-threatening adenovirus infections in severely ill or immunocompromised children, despite the lack of randomized controlled trials, according to the American Society of Clinical Oncology 4, 5
The dosing regimen for cidofovir is 5 mg/kg IV once weekly for 2 weeks, then once every other week, as recommended by the American Society of Clinical Oncology 4, 5
Mandatory monitoring of renal function is required due to the considerable nephrotoxicity risk associated with cidofovir, as stated by the American Society of Clinical Oncology 4, 5

The Centers for Disease Control and Prevention considers patients infectious for 10-14 days from symptom onset 6, 2
The World Health Organization recommends hand hygiene with soap and water, as adenovirus survives on surfaces for up to 28 days 6
The Centers for Disease Control and Prevention advises using dilute bleach for equipment disinfection and isolating infected children in hospitals and daycare settings to prevent outbreaks 6, 3, 1

The American Heart Association states that poor outcomes are associated with adenovirus serotype, particularly type 3 and 7, which have a worse prognosis 7, 8, 9
The American Academy of Pediatrics reports that age under 1 year with myocarditis shows a 5-year survival of only 66% with adenovirus versus 95% without 7, 8, 9

The American Academy of Pediatrics should consider adenovirus in the differential diagnosis when children present with fever ≥5 days, particularly when accompanied by conjunctivitis, pharyngitis, or respiratory symptoms 10, 11, 12
Adenovirus infection can be differentiated from Kawasaki disease based on clinical features, including fever persisting for a mean of 11 days without treatment in Kawasaki disease, versus 7-10 days for adenovirus 10, 11
The American Heart Association, as published in Circulation, notes that adenovirus commonly presents with exudative pharyngitis and discrete intraoral lesions, which would argue against Kawasaki disease 12
Both adenovirus and Kawasaki disease can show elevated inflammatory markers, making clinical features paramount for differentiation 10, 12
