Exclusion criteria

Exclusion criteria: 1. With suspicion of COVID-19 but not confirmed by RT-PCR test 2. Known history of any other pathology that could be confused with the diagnosis of long COVID: multiple sclerosis, autoimmune disease (lupus and Gougerot syndrome, inflammatory muscle disease, and myasthenia gravis), untreated hypothyroidism, major depression, regular use of narcotics 3.

Design outcomes

Primary

MeasureTime frame
Long-term COVID symptomatology measured using physical and cognitive questionnaires/parameters (Chalder scale, FAS, Promis) at baseline and 90 days

Secondary

MeasureTime frame
1. Observation of the evolution of the fatigue measured by the percentage of patients whose fatigue has decreased by 30% on the Chalder scale at 90 days compared to its initial state measured at baseline 2. Quality of life measured using SF-36 at baseline, day 28 and 90 days 3. Clinical symptoms, functioning, and quality of life evaluated using PROMIS at baseline, day 28 and 90 days 4. Long COVID fatigue symptomology measured by the Fatigue Assessment Scale (FAS) at baseline, day 28 and 90 days 5. Rate and evolution of autoimmune antibody markers within 90 days (posthoc analysis based on funding) analysed with Luminex/ELISA at baseline, day 5, day 10, day 28 and day 90
