Brief summary

The goal of this observational study is to learn about the long-term evolution of long COVID. The main question it aims to answer is: Does the main symptoms of the patients diagnosed with long COVID aproximate to those of patients who have had COVID acute infection without devoloping long COVID? Participants will answer mailed survey questions about their main symptons.

Detailed description

Scales, indexes and questionnaires were mailed to 40 patients with long COVID to evaluate their main symptoms. Fatigue, emotional disorders, sleep disorders, cognitive impairments, dyspnea, physical activity, quality of life and pain were analyzed. The patients were reassessed after three years.
