In rotavirus infections, factors influencing hospitalization were found to be emergency department observation time (hours) with an OR of 0.91, 95% CI (0.867–0.974) (p = 0.005), blood glucose levels with an OR of 1.03, 95% CI (1.02–1.05) (p = 0.002), serum potassium levels with an OR of 2.36, 95% CI (1.14–4.87) (p = 0.02), and CRP levels with an OR of 1.02, 95% CI (1.01–1.03) (p = 0.006) (Table 3). The gene discussed is CRP; the disease is Rotavirus infection.
