Prevalence of Cryptosporidium species in elementary school children.
The project described here was conducted to study the prevalence of various parasites in elementary school children in northern Jordan. A single stool specimen was collected from each of 1,000 students in the 6- to 14-year-old age group. A questionnaire covering demographic information, health status, and other relevant information was filled out by one of the parents of each student. Fresh stool specimens were processed by using wet mount preparations, formalin-ether, and Sheather's sugar flotation techniques. Permanently stained slides were prepared by acid-fast, Giemsa, and trichrome staining. Cryptosporidium species was found in 40 specimens (4%); however, only 15 specimens had Cryptosporidium species alone, and these 15 specimens were from symptomatic children with diarrheic stools. The symptoms reported most often were abdominal pain, cramps, malaise, nausea, and headache. The number of cases of infection was higher in villages, where contact with animals was evident and where contaminated drinking water could have been a major source of the infections.
