None of the 61 patients with systemic lupus erythematosus (SLE) surveyed was confirmed to have COVID-19. This is in contrast to the initial analysis of the COVID-19 Global Rheumatology Alliance registry, which shows an overrepresentation of SLE in patients with rheumatic diseases who have been diagnosed with COVID-192.
