Abstract
Background
Post-COVID-19 disease is not yet clearly described, presenting significant clinical variability across populations and patients. This paper compares post-COVID symptoms in three patient groups with mild, moderate, and severe infections in Ecuadorian outpatients.Methods
An epidemiological, observational, descriptive, and cross-sectional study was performed, and carried out in Quito, Ecuador. 1,366 non-hospitalized participants between 12 to 85 years, diagnosed with COVID-19 infection by molecular RT-PCR were included in the study. Demographic characteristics, including age groups, sex, ethnic group, work type, residence type, comorbidities, diagnosis, symptoms, and treatment were studied.Findings
1,366 outpatient Ecuadorian patients were analysed with SARS-CoV2 infection confirmed with a PCR+ test. The mean age was 39 (± 10) years, distributed by age groups ranging between 12 and 85 years; 81.41% were between 18 and 54 years. 50.29% were men, and 49.71% were women.Interpretation
64.3% of patients had symptoms between 4 to 6 weeks after infection, 21.1% showed ongoing symptoms between 6 to 12 weeks, and 14.6% had symptoms for more than 12 weeks. The most common symptom was fatigue in 67.3% of patients, followed by headache in 45.2%, body pain in 42.3%, and sleep disorders (insomnia, sleep apnoea, restless leg syndrome) in 36.5%. 69.3% of patients showed mild infection, 21.7% moderate, and 9.0% severe infection. On average, patients' daily life activities showed a 6.8% mean degree of impact following infection. A sedentary lifestyle (walking less than 30 minutes a day) was the most critical risk factor (40.3%), followed by being a health worker (11.87%). Patients aged ≥55 years with HTN, CKD, smoking, and sedentary lifestyle were 4.39, 1.92, 9.19, 4.07, and 2.42 times more likely to have a severe infection level. At least 30% of patients do not feel recovered from COVID-19 infection.Funding
