Intestinal helminthic and protozoal infections and urinary schistosomiasis in Egyptian children

Area of Science:

• Medical Parasitology
• Public Health
• Epidemiology

Background:

• Parasitic infections pose a significant health burden, particularly in developing countries.
• Understanding the geographic distribution and prevalence of these infections is crucial for effective control programs.
• Egypt faces challenges with various endemic parasitic diseases affecting child populations.

Purpose of the Study:

• To determine the current distribution and frequency of parasitic infections among school-aged children in Egypt.
• To provide updated epidemiological data on common intestinal and urinary parasites.
• To identify regional variations in infection rates across different governorates.

Main Methods:

• A cross-sectional study involving 2945 children aged 6-12 years.
• Collection and examination of one stool and one urine specimen per child.
• Data collection from schools located in Cairo, Giza Governorate, and the Nile Delta region.

Main Results:

• Schistosoma mansoni and Schistosoma haematobium infections showed marked regional variation, with higher rates in Giza and the Nile Delta.
• Intestinal parasitic infections such as ascariasis (3-31%), amebiasis (13-52%), and giardiasis (5-25%) were frequently observed.
• Lower rates were reported for strongyloidiasis, trichuriasis, and trichostrongliasis (<1%).
• Specific infections like Fasciola hepatica (0.01%) and Heterophyes heterophyes (8%) were noted in specific localities.

Conclusions:

• Parasitic infections remain a public health concern in Egyptian children, with significant geographic disparities.
• The findings highlight the need for targeted interventions and continued surveillance in high-prevalence areas.
• Updated epidemiological data are essential for guiding national control strategies against parasitic diseases.
