Functional characteristics of patients with SARS-CoV-2 pneumonia at 30 days post-infection

We read with great interest the series of cases reported by Mo et al. [1], describing pulmonary function after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in hospitalised patients. The authors describe a significant correlation between diffusing capacity of the lung for carbon monoxide (DLCO) and clinically defined pneumonia severity. More than half of patients with COVID-19 pneumonia exhibit abnormal lung function 30 days after symptom onset, without clear relationship with pneumonia extent on chest CT. This pleads for systematic and long-term follow-up of patients with COVID-19. https://bit.ly/2TFMPqE
