Prevalence and Seasonal Distribution of Protozoal Infections Entamoeba Histolytica and Giardia Lamblia in Dir Lower

Background: The research examines the prevalence and seasonal distribution of protozoal infections—Entamoeba histolytica and Giardia lamblia—in Dir Lower, 2021, highlighting distinct patterns. Results: E. histolytica consistently recorded higher infection rates year-round, with a significant peak in August, likely tied to warmer temperatures that enhance both water contamination and protozoal survival. G. lamblia cases, although fewer, exhibited modest increases in late winter and summer, potentially due to post-rainy conditions favorable to its transmission. Age and gender analysis revealed a higher prevalence of G. lamblia among male children in the 11–20 age group, possibly due to increased outdoor exposure and water contact, while females showed slightly lower infection rates. Conclusion: The study underscores a need for age-specific interventions, particularly for boys under 15, to curb infections effectively. Emphasizing targeted strategies during summer and vacation periods, the research provides critical insights for designing more focused public health measures to control protozoal transmission in the Dir Lower community
