For each country, the top three most frequently detected pathogens (out of the nine considered) among eligible children ages 0 to 23 months (left half of the plot) and 24 to 59 months old (right half) are shown. Bar heights are proportional to the percent of cases positive for a pathogen (which is also printed below each bar), and the pathogens are indicated by abbreviations and color as summarized in the legend. Pathogens considered are: rotavirus, adenovirus 40/41, norovirus GI, norovirus GII, Cryptosporidium, Shigella, ST-ETEC, Campylobacter, and V. cholerae. Note that the seasons are not plotted in a particular order and may be non-sequential.
