ObjectivesDescribe and evaluate the outcome of a coronavirus disease-2019 (COVID-19) patient without shortness breath.Design methodsWe retrospectively collected data from COVID-19 patients diagnosed cared for in Marseille, France. We selected who at admission, had low dose CT scanner, dyspnea status, oxygen saturation available. Blood gas was analyzed sample subset patients.ResultsAmong 1712 with COVID-19, we report that 1107 (64.7%) do not complain breath admission. The low-dose computed tomography (LDCT) scan showed signs compatible pneumonia 757/1,107 (68.4%) dyspnea. In underwent least one blood analysis (n = 161) presented 28.1% (27/96) hypoxemia/hypocapnia syndrome. Asymptomatic hypoxia associated very poor (33.3% were transferred to ICU 25.9% died).ConclusionThe absence an old comorbidity merit medical attention should be considered as good sign well-being. prognosis asymptomatic hypoxia, highlight severity this mild clinical presentation. these patients, pulse oximetry is important mean predict along news score LDCT scanner.
