Note. ccCoV, common-cold coronavirus; hMPV, human metapneumovirus; hRV/EV, human rhinovirus/enterovirus; IQR, interquartile range; PIV, parainfluenza; RSV, respiratory syncytial virus; SIRS, systemic inflammatory response syndrome.
Competing risks of discharge and death were modeled in Cox proportional hazards models with time-varying HARVI status.
Adjusted models included the following covariates: Age (years), sex, non-Hispanic Black race/ethnicity, CCI score (adults), CCC score (children), meeting ≥2 SIRS criteria (adults), and peak season admission (December, January, February, or March).
