الوصف: It is presently unknown whether imported cases of the 2019 coronavirus disease (COVID-19) have different characteristics when compared with local cases. To compare the clinical characteristics of local cases of COVID-19 in China compared with those imported from abroad. This was a retrospective study of confirmed cases of COVID-19 admitted at the Beijing Ditan Fever Emergency Department between February 29 th , 2020, and March 27 th , 2020. The clinical characteristics of the patients were compared between local and imported cases. Compared with local cases, the imported cases were younger (27.3 ± 11.7 vs. 43.6 ± 22.2 years, P < .001), had a shorter interval from disease onset to admission (1.0 (0.0–2.0) vs 4.0 (2.0–7.0) days, P < .001), lower frequencies of case contact (17.4% vs 94.1%, P < .001), fever (39.1% vs 82.4%, P < .001), cough (33.3% vs 51.0%, P = .03), dyspnea (1.9% vs 11.8%, P = .01), fatigue (7.5% vs. 27.5%, P = 0.001), muscle ache (4.7% vs. 25.5%, P < 0.001), and comorbidities ( P < .05). The imported cases were less severe than the local cases, with 40.4% versus 5.9% mild cases, 2.8% versus 15.7% severe cases, and no critical cases ( P < .001). The length of hospital stay was longer in imported cases than in local cases (32.3 ± 14.5 vs 21.7 ± 11.2 days, P < .001). The imported cases showed smaller biochemical perturbations than the local cases. More imported cases had no sign of pneumonia at computed tomography (45.0% vs 14.9%, P = .001), and none had pleural effusion (0% vs 14.9%, P < .001). Compared with local cases, the imported cases of COVID-19 presented with milder disease and less extensive symptoms and signs.
