Clinical characteristics and outcomes of confirmed COVID-19 patients in the early months of the pandemic in Tanzania: A multicentre cohort study

Background We performed a prospective cohort study of the clinical presentations and management outcomes of laboratory-confirmed COVID-19 patients in the early months of the pandemic at two hospitals in Dar es Salaam, Tanzania. Methods Between April 1 - May 31, 2020, laboratory-confirmed COVID-19 patients seen at two tertiary facilities were consecutively enrolled in the study and followed up for 21 days. Results We enrolled 121 COVID-19 patients; 112 (92.6%) were admitted while 9 (7.4%) were seen as outpatients. The median (IQR) age of patients was 41 (30-54) years; 72 (59.5%) were male. The medians (IQR) reported days from hospital admission to recovery and death was 10 (6-18) and 5.5 (3-9), respectively. Forty-four (36.4%) patients had at least one underlying condition. Of the 112 admissions, 17 (15.2%) went to ICU, of which 14 (82.3%) died. At the end of follow-up, 93(76.9%) recovered, and 18 (14.9%) died, 7 (5.8%) remained asymptomatic, and 1 (0.8%) was still ill. Overall, 46 (38.3%) patients had at least one underlying condition. Conclusion Three-quarters of all COVID-19 patients were aged less than 60 years, reflecting Africa's young population structure. High admission rates to ICU and death rates were observed
