Abbreviations: OR, odds ratio; aOR, adjusted odds ratio; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2. Models adjusted for age, sex, country of origin, socioeconomic deprivation, prior SARS-CoV-2 diagnosis, number of comorbidities, and HIV status. * Socioeconomic deprivation is based on the index of the Catalan government according to the basic health area (ABS) of residence. This index is based on five indicators which are: proportion of manual workers, proportion of residents with low education level, proportion with low income, rate of premature mortality, and rate of avoidable hospitalization.
