This study purposed to identify COVID-19 clinical characteristics, disease severity and mortality rates of patients admitted to UNS Hospital. Method: Data for 205 UNS Hospital patients were taken ret- rospectively from June - November 2020. Medical records were obtained including gender, age, clinical symptoms and comorbidities according to the disease severity. Data analysis was performed using a descriptive method using the Microsoft Excel 2019 application to determine the prevalence of each clinical characteristic based on the disease severity and mortality rate. Results: Total data were 205 analyzed, 50.7% female and 49.3% male, the most age group was 19-39 years (43.4%). Patients divided into mild, moderate and severe categories were 53.7%, 34.1% and 12.2%. Clinical symptoms include cough (64.88%), fever (47.8%), shortness of breath (45.4%), malaise (23.41%), nausea (20.49%). Meanwhile, the dominant comorbid factors were hypertension (24.3%) and diabetes mellitus (17.1%). The highest mortality rate was 40-59 years (52%). Duration of treatment 10-14 days. Conclusion: Clinical characteristics of confirmed SARS-COV-2 patients found at UNS Hospital still vary widely, with mild to severe symp- toms with the comorbid DM and hypertension dominating the death of COVID-19 patients.
