School Nurse–Led Intervention Framework for Intestinal Parasitic Infections in Conflict-Affected Yemen: A Cross-Sectional Study Informing Public Health Action

Study Overview: A school-based cross-sectional study conducted between January and June 2024 in Ad'Dla Governorate, Yemen, involving 480 primary school children (6-12 years). The study aimed to determine the prevalence, distribution, and risk factors of intestinal parasitic infections (IPIs) and to develop an evidence-based, nurse-led intervention framework for resource-limited, conflict-affected settings. Key Findings: · Overall IPI prevalence: 46.0% (221/480) · Protozoan infections predominated (86.0%), primarily Entamoeba histolytica/dispar (48.9%) and Giardia lamblia (37.6%) · Significant risk factors: Rural residence (AOR=2.25), unimproved water (AOR=1.71), unimproved sanitation (AOR=1.68) · No significant associations with age or sex Repository Contents: 1.
