RESUMEN
Introduction: post-COVID-19 syndrome is the set of signs and symptoms that develop during or after an infection compatible with COVID-19, that persist for more than 12 weeks and are not explained by an alternative diagnosis. Background: to characterize the clinical-epidemiological behavior of the post-COVID-19 syndrome in patients at the Andres Ortiz Polyclinic. Method: a descriptive and cross-sectional observational study was carried out from October to December 2021, in a population of 51 subjects that was studied in its entirety. The analysis was descriptive. Results: patients with 50-59 years (n = 20;39.2%), female (n = 32;62.7%) predominated. The most frequently affected organ system was the respiratory (n = 19;37.2%), while the symptoms were: chronic fatigue (n = 15;29.4%), shortness of breath (n = 11;21.5%) and cough (n = 8, 15.6%). Among the patients with respiratory (n = 30), cardiovascular (n = 24) and neurological (n = 10) diseases, the most frequent were, respectively: pulmonary fibrosis (n = 17;56.7%), cardiac arrhythmias (n = 11;45.8%) and peripheral neuropathies (n = 5;50%). Conclusions: post-COVID-19 syndrome occurred mainly between the ages of 50 and 59, in female patients, with symptoms of chronic fatigue, shortness of breath and cough, as well as pulmonary fibrosis, cardiac arrhythmias and peripheral neuropathies as main comorbidities.
