We conducted a cohort study using de-identified data from the Western Cape Provincial Health Data Centre (WCPHDC) of public sector patients aged ≥20 years with documented sex and not known to have died before March 1, 2020 (before the first diagnosed COVID-19 case in South Africa, and several weeks before the first documented COVID-19 death) and included all follow up through June 9, 2020. We used Cox-proportional hazards models adjusted for age, sex and other comorbidities to examine the association between HIV, tuberculosis and COVID-19 death among (i) all public sector patients with ≥1 health visit in the 3 years before March 1, 2020 (considered "active patients"), (ii) laboratory-diagnosed COVID-19 cases and (iii) hospitalized COVID-19 cases.	./cache/cord-279828-es498qul.txt	./txt/cord-279828-es498qul.txt
