Summary

This study tested whether teaching hand and respiratory hygiene to primary school children could lower how often they get sick and miss school. Over 800 students in Erbil, Iraq, took part. Some schools got hygiene lessons and reminders, while others did not. The goal was to see if a simple, low-cost program could prevent common respiratory and stomach illnesses.

Eligible participants were children enrolled in grades four to six (aged 9-13 years) attending public schools within Erbil city center. All students in the selected schools were invited to participate. Written informed consent was obtained from parents or guardians, and verbal agreement was provided by the children prior to enrollment. Exclusion Criteria: * Exclusion criteria included students attending private, evening, or special schools (e.g., for children with disabilities), as well as those with chronic medical conditions likely to influence school attendance. Bilingual schools (English-Arabic) were excluded to maintain comparability in the educational environment.
