In this study, the investigators are attempting to evaluate the influence of socio-economic factors on the functional recovery (physical and psychological) of patients who developed ARDS after a COVID-19 infection, with the aim of offering personalized medical and social follow-up and support measures in order to avoid medium- and long-term complications, which can result in handicaps, reduced quality of life, and a higher risk of death.

Inclusion Criteria:

• Inpatient in ICU for PCR-proven SARS-VOC-2 infection regardless of specimen type
• Patient who received a chest CT scan in the initial phase of management (either just before or during hospitalization in the intensive care unit)
• Patient who has received invasive or non-invasive ventilatory support, or humidified and heated high-flow oxygen (HFO).
• ARDS meeting the criteria of the 2012 Berlin definition. For patients who have received only HFO, a flow rate at least equal to 50L/minute with a FiO2 strictly greater than 50% with a PaO2/FiO2 ratio less than or equal to 200 will be required for inclusion.
• Patient who gave oral consent after being informed about the conduct of this study.

Exclusion Criteria:

• Patient with limited autonomy prior to hospitalization in limited intensive care unit: walking distance of less than 50 meters, WHO classification status 3 and 4.
• Patient with a history of chronic respiratory failure as defined by the use of long-term oxygen therapy or non-invasive home ventilation, excluding patients with SAS and/or hypoventilation obesity syndrome.
• Patient with a history of central or peripheral neurological conditions limiting the patient's motor autonomy and the performance on gait tests or Pulmonary function Tests
• Patient refusing to participate
• Patient < 18 years of age
• Patient not affiliated or not benefiting from national health insurance
• Patient under guardianship, curatorship or protected adult
• Patient unable to understand and consent to the research protocol

SECONDARY EXCLUSION CRITERIA

• Patient not showing up for visit at M6
• Patients who have not had all the examinations necessary to evaluate the main endpoint (Spirometry, DLCO, TM6 and CT)

Patient who has been managed in intensive care for covid-19 infection.
