FIG. 2.

Cumulative incidence of primary enteric infections with bacterial agents (A) and parasites and rotavirus (B) in a cohort study of 200 children monitored from birth until up to 2 years of age in Guinea-Bissau from 1996 to 1998. For the microorganisms that infected <50% of the children, the median age at which 25% of the children are infected is reported. Stx1-producing STEC, Isospora spp., and E. histolytica or E. dispar infected <25% of the children and the results are therefore not shown. The results for G. lamblia, Entamoeba coli, C. mesnilli, and Endolimax nana represent the detection of cysts, trophozoites, or both.
