A, Viral loads of norovirus, astrovirus, and sapovirus in stool specimens in acute gastroenteritis (AGE) case patients and healthy controls (HCs), shown as cycle threshold (Ct) values. B, Viral loads of norovirus, astrovirus, and sapovirus in stool specimens by singly detected and codetected viruses. C, Comparison of Ct values between subjects by age groups. D, Viral loads of norovirus, astrovirus, and sapovirus in stool specimens by clinical setting. Data are shown as medians with 95% confidence intervals, and P values were calculated using the Wilcoxon rank sum test (NS, not significant). Note that Ct values were missing for 1 norovirus-positive and 1 sapovirus–positive case patient (both <5 years old). Abbreviations: AGE, acute gastroenteritis; Ct, cycle threshold; ED, emergency department; HCs, healthy controls.
