This longitudinal study provides a rigorous quantitative analysis of the relationship between climatic variables and intestinal parasitic infections (IPIs) in Babil Governorate, Iraq, from January 2022 to April 2024. Data from 2,148 confirmed patient records across three major hospitals were correlated with high-resolution meteorological data. Our analysis reveals a 45.8% increase in total IPI incidence, rising from 512 cases in 2022 to 747 cases in 2024, strongly associated with a 2.3 °C temperature increase and a 35% reduction in annual rainfall. Multivariate regression models demonstrated that maximum temperature was the strongest predictor of Giardia lamblia incidence (β = 0.82, p < 0.001), while drought duration showed significant association with Entamoeba coli infections (β = 0.71, p = 0.003). Humidity levels were inversely correlated with overall IPI prevalence (r = -0.79, p < 0.01). Children under 10 years showed 3.2 times higher infection risk during drought periods (OR = 3.2, 95% CI: 2.1-4.8), and significant gender-specific patterns emerged across parasite species. These findings provide compelling evidence for climate-driven disease amplification and underscore the urgent need for integrated public health interventions that address both environmental and demographic risk factors.
