Seasonality of pediatric diarrhea according to pathogen, 2010–2012. (A) Numbers of stool specimens tested according to month are presented as the overall height of the bars. Stacked within each of these bars are the numbers of bacterial, viral, protozoal, and mixed (bacterial + viral, bacterial + protozoal, or viral + protozoal) detections and negative test results (white). (B) Detection of enteric bacterial pathogens. (C) Detection of viral pathogens. (D) Detection of protozoal pathogens. The number of diarrheal episodes in which each pathogen was identified are presented as stacked bar graphs for each month of the 2-year study period. Abbreviations: EAEC, enteroaggregative E coli; EIEC, enteroinvasive E coli; EPEC, enteropathogenic E coli; ETEC, enterotoxigenic E coli; STEC, shigatoxigenic E coli.
