Abstract:
INTRODUCTION:Coronavirus disease 2019 (COVID-19), a potentially fatal disease, is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The number of cases has increased rapidly, but information on the clinical characteristics remains limited. METHODS:Cohort study. We collected and analyzed epidemiological, demographic, and clinical data of critically and noncritically ill patients and compared the outcomes. RESULTS:The mean age of hospitalized patients with COVID-19 was 54 years (standard deviation 16.9; 53.8% men), 29% required ICU admission, and 18.6% died. CONCLUSIONS:The main risk factors for ICU admission were age over 60 years, obesity, and preexisting chronic lung diseases.
