Clinical features in mild type and severe type of COVID-19 patients

Abstract Background Coronavirus Disease 2019 (COVID-19) outbroke in Wuhan and spread to the world quickly. We aim to describe the clinical features and compare them between mild type and severe type of COVID-19 patients. Methods Laboratory confirmed COVID-19 patients were included in this study. Patients’ demographic data and clinical data were recorded and compared between mild type and severe type. Results Fifteen patients were confirmed COVID-19 and enrolled in this study. Six patients were of mild type, while 9 patients were of severe type. Statistical differences were found between mild type and severe type patients in retirement, epidemiological history, baseline blood level of lactate dehydrogenase and Oxygenation Index (All p < 0.05). All patients had ground-glass opacities without consolidation in initial chest computed tomography images, 2 (16.7%) patients had pulmonary nodules. There were no statistical differences between mild type and severe type patients in initial chest CT findings (All p > 0.05). Conclusions Differences can be found in baseline clinical features between mild type and severe type of COVID-19 patients to help health care providers making early judgement to the severity and proper treatment.
