Prevalence of Cryptosporidium species in elementary school children
1Department of Biological Sciences, Faculty of Science, Jordan University of Science and Technology, Irbed.
Insights
Prevalence of parasites in 1,000 Jordanian elementary students revealed Cryptosporidium species in 4% of cases. Infections were linked to symptomatic children, villages, and potentially contaminated water sources.
Area of Science:
- Environmental Health
- Infectious Diseases
- Pediatric Parasitology
Background:
- Parasitic infections pose a significant health burden, particularly in school-aged children.
- Understanding parasite prevalence is crucial for implementing effective public health interventions.
- Northern Jordan's specific environmental and socioeconomic factors may influence parasitic disease transmission.
Purpose of the Study:
- To determine the prevalence of various parasites among elementary school children in northern Jordan.
- To identify risk factors associated with parasitic infections in this population.
- To investigate the clinical manifestations and potential sources of infection, focusing on Cryptosporidium species.
Main Methods:
- A cross-sectional study involving 1,000 elementary school students (ages 6-14) in northern Jordan.
- Stool specimen collection and analysis using wet mount, formalin-ether, and Sheather's sugar flotation techniques.
- Microscopic examination of permanently stained slides (acid-fast, Giemsa, trichrome) for parasite identification.
Main Results:
- Overall parasite prevalence was assessed, with Cryptosporidium species identified in 40 specimens (4%).
- Of the 40 Cryptosporidium-positive cases, 15 (37.5%) were symptomatic with diarrhea, abdominal pain, cramps, malaise, nausea, and headache.
- Higher infection rates were observed in villages with animal contact and potential for contaminated drinking water sources.
Conclusions:
- Cryptosporidium species infection is present in northern Jordanian schoolchildren, with a notable proportion of symptomatic cases.
- Village environments with animal contact and contaminated water are potential risk factors for parasitic infections.
- Further research and targeted public health strategies are needed to control parasitic diseases in this vulnerable population.
Abstract:
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.
