COVID pneumonia patients from August 2020 to January 2021 were analyzed (n=72), with a standardized clinical follow-up a month after discharge. We describe clinical features, extent of pneumonia and treatment provided. We define Extent Pneumonia as an affection of ≥ 4 of 6 radiographic zones and/or 3 of 5 lobes in chest CT and compare vs Non extent pneumonia. Lastly, we describe the findings on the clinical follow-up.Results: Table 1: Cohort´s description. Table 2: Extent and Non extent pneumonia comparison. Clinical follow-up: 8(11.1%) patients persist symptomatic after discharge (4cough-3dyspnea-1anosmia).
