Objective: Cryptosporidiosis is an important enteric parasitic infection among infants and children in developing countries with significant morbidity and mortality especially among immuno-suppressed individuals. The aim of the present study was to estimate the prevalence of enteric cryptosporidiosis in children presenting with diarrhea in Isfahan.
Methods: This cross-sectional study was conducted from August 2007 to June 2008 in three university hospitals in Isfahan. Children aged 1 month to 10 years presenting with acute or persistent diarrhea were selected consecutively. The oocyst of C. parvum was investigated in stool specimens using a modified acid-fast staining method.
Findings: During the study period, 606 children (mean age 42.4±30.0 months, 58.1% female) were recruited. Acute and persistent diarrhea was present in 422 (69.6%) and 184 (30.4%) of the children, respectively. Twenty eight (4.6%) specimens were oocyst positive. The prevalence of Cryptosporidium infection was significantly higher in children with persistent diarrhea compared to children with acute diarrhea (12.5% vs 1.2%; P<0.001). Most of the infected children were under 5 years of age (89.2%), however, the age difference between infected and non-infected children was not statistically significant. Also, there was no significant difference between infected and non-infected children in gender.
Conclusion: The prevalence of Cryptosporidiosis in children presenting with persistent diarrhea is considerable and we suggest routine stool examination for Cryptosporidium in this group of children.
