  1. Prevalences at 95 % CIs for single infections and co-infections with enteric pathogens among case (at least five stools/24 h) and control children aged below five years in Kunming, southwest China. Children were sampled during the wet (May to October, n = 371) and dry (November to April, n = 649) seasons. Odd ratios between case (n = 850) and control (n = 170) children were estimated at 95 % CIs. The asterisk (*) indicates statistical differences (calculated using the chi-square or Fisher’s exact tests) in pathogen prevalence between case and control children in both seasons. The “- -” symbol indicates that no cases were detected. Infections with various DEC subtypes (i.e., EAEC, EPEC, EAEC, EHEC, and ETEC) were combined into a single category (DEC). Only co-infections found in at least 10 individuals (1 % of children) have been shown
