    ImportanceCompared with seasonal influenza, the clinical features and epidemiologic characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and coronavirus 2019 (COVID-19) in US children remain largely unknown.ObjectiveTo describe the similarities and differences in clinical features between COVID-19 and seasonal influenza in US children.Design, Setting, And ParticipantsThis retrospective cohort study included children who were diagnosed with laboratory-confirmed COVID-19 between March 25 and May 15, 2020, and children diagnosed with seasonal influenza between October 1, 2019, and June 6, 2020, at Children's National Hospital in the District of Columbia.ExposuresCOVID-19 or influenza A or B.Main Outcomes And MeasuresRates of hospitalization, admission to the intensive care unit, and mechanical ventilator use and the association between underlying medical conditions, clinical symptoms, and COVID-19 vs seasonal influenza.ResultsThe study included 315 patients diagnosed with COVID-19 (164 [52%] male; median age, 8.3 years [range, 0.03-35.6 years]) and 1402 patients diagnosed with seasonal influenza (743 [53%] male; median age, 3.9 years [range, 0.04-40.4 years]). Patients with COVID-19 and those with seasonal influenza had a similar hospitalization rate (54 [17%] vs 291 [21%], P = .15), intensive care unit admission rate (18 [6%] vs 98 [7%], P = .42), and use of mechanical ventilators (10 [3%] vs 27 [2%], P = .17). More patients hospitalized with COVID-19 than with seasonal influenza reported fever (41 [76%] vs 159 [55%], P = .005), diarrhea or vomiting (14 [26%] vs 36 [12%], P = .01), headache (6 [11%] vs 9 [3%], P = .01), body ache or myalgia (12 [22%] vs 20 [7%], P = .001), and chest pain (6 [11%] vs 9 [3%], P = .01). Differences between patients hospitalized with COVID-19 vs influenza who reported cough (24 [48%] vs 90 [31%], P = .05) and shortness of breath (16 [30%] vs 59 [20%], P = .13) were not statistically significant.Conclusions And RelevanceIn this cohort study of US children with COVID-19 or seasonal influenza, there was no difference in hospitalization rates, intensive care unit admission rates, and mechanical ventilator use between the 2 groups. More patients hospitalized with COVID-19 than with seasonal influenza reported clinical symptoms at the time of diagnosis.
