*AGE episodes were defined based on self-report as any illness in the previous 30 day with diarrhea or vomiting that included >3 loose stools in any 24-hour period. Data from participants who completed the survey on or before the 15th of the month were included in estimates for the preceding month, whereas information from surveys completed after the 15th contribute to the current month. Prevalence estimates are weighted to account for the sampling scheme; 95% CIs are estimated using exact (Clopper-Pearson) formulas. AGE, acute gastroenteritis. †Survey design-based F-tests comparing differences in proportion of AGE across age groups are significant for both the diarrhea or vomiting definition (p = 0.0014) and the diarrhea definition (p<0.001). ‡Survey design-based F-tests comparing differences in proportion of AGE across sex are not significant for either the diarrhea or vomiting definition (p = 0.264) nor the diarrhea definition (p = 0.112).
