ABSTRACT

Objective: In this study, we tried to evaluate the asymptomatic rate, case fatality rate and total duration of hospital stay of admitted patients with COVID-19. Methodology: We conducted a retro-prospective study of 384 patients admitted into the Mugda Medical College and Hospital, Dhaka, Bangladesh in between May 1, 2020 and June 31, 2020. Data were obtained from patient charts and the hospitals’ admission records using a structured questionnaire. Result: Among 384 patients about 34 (8.9%) were asymptomatic and in symptomatic patient the median time from illness onset (before admission) to discharge was 19·0 days, whereas the median time to death was 9.0 days. The median time from hospital admission to discharge alive was 14.0 days, whereas the median time to death was 3.0 days. The most common symptoms on admission were fever (21, 70.6%). Case fatality rate was 25.5% (98/384×100). Conclusion: Moving forward, we hope to continue to deliver early and optimal care, limit community transmission, and tying the case fatality to the lower end of the known range.
