Note. Data presented are median (interquartile range: low 25%, high 25%). CRP = C-reactive protein; WBC = white blood cell; Asympt/mild = asymptomatic/mild: not hospitalized; Mod = moderate: hospitalized but not requiring ICU; severe/critical = hospitalized, requiring mechanical intubation, +/− ICU admission.
