Objective To investigate the infection and distribution characteristics of Cryptosporidium and Cryptosporidium in patients with diarrhea. METHODS: From March to October of each year from 1997 to 2000, 377 diarrhea patients in 7 pilot counties (cities and districts) in Yunnan Province were collected for their stool samples, and iodine solution Direct smear and stool smear acid-fast staining. Results The total infection rate of Cryptosporidium and Cryptosporidium in 378 cases of diarrhea in 7 counties (cities and districts) were 3.97% and 5.92%, respectively, among which the infection rate was highest in preschool children, The infection rates of sporozoites were 10.64% and 8.51% respectively. Cryptosporidium was detected in 3 counties of Luoping, Yuanyang and Pu’er. Cryptosporidium was detected in 6 counties (cities) in Lushui County, Jinghong City, Pu’er County, Luoping County, Yuanyang County and Kunming Xishan District Out Conclusions Cryptosporidiosis is endemic and Cryptosporidium is widely distributed. The prevalence of two species of sporozoites in preschool children is high.
