Obstructive sleep apnoea (OSA) is the most frequent form of sleep disordered breathing (SDB) [2], which may represent a relevant risk factor for the clinical course and prognosis of coronavirus disease 2019 (COVID-19) [3, 4]. Common characteristics and comorbidities of OSA and COVID-19 (male gender, age &gt;60 years, metabolic syndrome, cardiovascular and chronic pulmonary disease) were recently described as prognostic factors in COVID-19 [5]. However, the prevalence of SDB after COVID-19 remains insufficiently explored.Sleep disordered breathing may be a risk factor or a sequela of COVID-19. https://bit.ly/37v5Gyz ER -
