Purpose of the Study:

• To determine the prevalence of intestinal protozoa and helminths in primary school children in Abha, Saudi Arabia.
• To analyze the distribution of infections based on age, nationality, and co-infection patterns.

Main Methods:

• Stool specimens were collected from 1282 children aged 5-13 years attending 10 primary schools.
• Microscopic examination was used to identify intestinal protozoa and helminths.

Main Results:

• Overall prevalence of intestinal parasites was 24.4% (313/1282).
• The most common protozoa were Giardia lamblia (10.9%) and Entamoeba histolytica (4.1%). Entamoeba coli had a prevalence of 11.3%.
• Hymenolepis nana was the most prevalent helminth (3.0%). Infection rates were higher in Yemeni children.

Conclusions:
