  abstract = {{O}bjectives: {D}escribe and evaluate the outcome of a coronavirus disease-2019 ({COVID}-19) patient without shortness of breath. {D}esign and methods: {W}e retrospectively collected data from {COVID}-19 patients diagnosed and cared for in {M}arseille, {F}rance. {W}e selected data from patients who at admission, had a low dose {CT} scanner, dyspnea status, and oxygen saturation available. {B}lood gas was analyzed in a sample subset of patients. {R}esults: {A}mong 1712 patients with {COVID}-19, we report that 1107 (64.7%) do not complain of shortness of breath at admission. {T}he low-dose computed tomography ({LDCT}) scan showed signs compatible with pneumonia in 757/1,107 (68.4%) of patients without dyspnea. {I}n a subset of patients who had underwent at least one blood gas analysis (n = 161) and presented without dyspnea at admission, 28.1% (27/96) presented with a hypoxemia/hypocapnia syndrome. {A}symptomatic hypoxia was associated with a very poor outcome (33.3% were transferred to the {ICU} and 25.9% died). {C}onclusion: {T}he absence of shortness of breath in an old patient with comorbidity merit medical attention and should not be considered as a good sign of well-being. {T}he poor prognosis of asymptomatic hypoxia, highlight the severity of this mild clinical presentation. {I}n these patients, pulse oximetry is an important mean to predict the outcome along with news score and {LDCT} scanner.},
