Two studies were done on cryptosporidiosis in children. A retrospective survey showed that from 2005 to 2015, Cryptosporidium species was detected by microscopy of stool from 0.25% of children with diarrhea. In a subsequent prospective study, polymerase chain reaction detected Cryptosporidium species in 4 (1.3%) of 304 children. Cryptosporidium species is as frequent as other intestinal pathogens in childhood diarrhea. Testing is relevant.
