*Because of missing data for some responses, values might not add up to 100%. For missing SARS-CoV-2 testing date, we used reported date of illness onset instead. In total, 56 patients had no date information and could not be assigned to a specific wave, of which 54 reported mild illness and 2 reported severe illness. †Missing data for sex, n = 13, and age, n = 20. ‡Missing data for sex, n = 1.
