IQR, interquartile range; LOS, length of stay; WBC, white blood cell count.

*P*values based on Kruskal–Wallis test for continuous variables and Fisher’s exact test for categorical variables.Peripheral WBC, peripheral ANC, CSF WBC, CSF ANC, and CSF protein were natural logarithm transformed to obtain normal distributions.

↵a Enterovirus season is June–October.
