We identified 9,519 SARS-CoV-2 PCR-positive cases of whom 78% were community-managed, 22%
were hospitalized (3.2% at an intensive care unit) and 5.5% had died within 30 days. Median age varied
from 45 years (interquartile range (IQR) 31-57) among community-managed cases to 82 years (IQR 75-
89) among those who died. Age was a strong predictor of fatal disease (odds ratio (OR) 14 for 70-79-
year old, OR 26 for 80-89-year old, and OR 82 for cases older than 90 years, when compared to 50-59-
year old and adjusted for sex and number of comorbidities). Similarly, the number of comorbidities was
strongly associated with fatal disease (OR 5.2, for cases with ≥4 comorbidities versus no
comorbidities), and 82% of fatal cases had at least 2 comorbidities. A wide range of major chronic
diseases were associated with hospitalization with ORs ranging from 1.3-1.4 (e.g. stroke, ischemic heart
disease) to 2.2-2.7 (e.g. heart failure, hospital-diagnosed kidney disease, chronic liver disease). Similarly,
chronic diseases were associated with mortality with ORs ranging from 1.2-1.3 (e.g. ischemic heart
disease, hypertension) to 2.4-2.7 (e.g. major psychiatric disorder, organ transplantation). In the absence
of comorbidities, mortality was relatively low (5% or less) in persons aged up to 80 years.
