Abstract

Background: Coronavirus disease 19 (COVID-19) is a recently described infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Iran was the first country where the SARS-Cov-2 was detected in the Middle East. In the current study, we aimed to evaluate the clinical, radiological and laboratory findings in hospitalized COVID-19 confirmed cases in Iran. Methods: The clinical manifestations, radiological data, laboratory findings, and the underlying diseases of the patients with COVID-19 were obtained from electronic medical records. Next, this information was compared in discharged and dead patients. Results: Overall, 4028 patients with COVID-19 including 3088 discharged, 778 dead, and 162 still hospitalized patients were enrolled in this study. The highest percentage of people who recovered (55) was between 30 and 60years old and the highest percentage of deaths (74.4) was more than 60years old. Based on demographic data, 50.05 were female and 49.95 were male. Clinical evaluations revealed that dyspnea (56.9), cough (31.4) and fever (17.8) were the most manifestations. Comorbidities were significantly higher in the dead group. Laboratory analysis revealed abnormalities in lymphocyte count (LYM), erythrocyte sedimentation rate (ESR), and inflammatory biomarkers such as C-reactive protein (CRP). The most prevalent computed tomography (CT) scan data were ground-glass opacity (GGO) (30.5) and consolidation (9.4). Conclusions: Laboratory parameters and clinical and radiological findings help to evaluate the follow-up of the disease in patients. Age and comorbidities are factors that predispose people to COVID-19. Further research is needed to evaluate the effects of various factors on the progression of COVID-19 infection.
