↵* Ordinal regression was performed to compare the 5-level ordinal outcomes at 15 days and 30 days since diagnosis. Age, immunocompromised state and location of infection acquisition (shown to be significant in univariate analyses) were included as covariates in each model. Analyses limited to community-acquired infections showed no significant difference between virus groups; the variable “sex” was also insignificant (data not shown). For hCoV, the ordinal outcomes at 30 days were as follows: 81.6% discharged, 3.4% in convalescent hospital care, 4.6% in acute hospital care, 1.1% in ICU care and 9.2% died.
