“…The first published studies of children reported few findings in radiographs 15 ; however, subsequent reports have revealed a higher proportion of radiographic abnormalities 11 , which depend on the severity of pulmonary involvement 31,32 . In adults, most computed tomography studies in SARS-CoV-2-associated CAP show ground-glass opacities (25-60% according to different studies) [33][34][35][36][37][38] that can progress to white lung. The proportion of white lung in children is low, and the mechanism is worth further study.…”

Pneumonia is a frequent manifestation of COVID-19 in hospitalized children. Methods The study involved 80 hospitals in the SARS-CoV-2 Spanish Pediatric National Cohort. Participants were children <18 years, hospitalized with SARS-CoV-2 community-acquired pneumonia (CAP). We compared the clinical characteristics of SARS-CoV-2-associated CAP with CAP due to other viral etiologies from 2012 to 2019. Results In total, 151 children with SARS-CoV-2-associated CAP and 138 with other viral CAP included. Main clinical features of SARS-CoV-2-associated CAP were cough 117/151(77%), fever 115/151(76%) and dyspnea 63/151(46%); 22/151(15%) patients were admitted to a pediatric intensive care unit (PICU), and 5/151(3%) patients died. Lymphopenia was found in 63/147(43%) patients. Chest X-ray revealed condensation (64/151[42%]) and other infiltrates (87/151[58%]). Compared with CAP from other viral pathogens, COVID-19 patients were older (8 vs.1 year; odds ratio [OR] 1.42 [95% confidence interval, CI 1.23;1.42]), with lower CRP levels (23 vs.48 mg/L; OR 1 [95%CI 0.99;1]), less wheezing (17 vs.53%; OR 0.18 [95%CI 0.11;0.31]) and greater need of mechanical ventilation, MV (7 vs.0.7%, OR 10.8 [95%CI 1.3;85). Patients with non-SARS-CoV-2-associated CAP had a greater need for oxygen therapy (77 vs.44%, OR 0.24 [95%CI 0.14;0.40]). There were no differences in the use of CPAP or HVF or PICU admission between groups. Conclusion SARS-CoV-2-associated CAP in children presents differently to other virus-associated CAP: children are older and rarely have wheezing or high CRP levels; they need less oxygen but more CPAP or MV. However, several features overlap, and differentiating the etiology may be difficult. The overall prognosis is good.
