Malnutrition (AOR = 2.89; 95%CI: 1.584–8.951; p = 0.039), cow dung use (AOR =2.21; 95%CI: 1.121–9.373; p = 0.014), presence of smoker in the family (AOR = 0.638; 95% CI: 0.046–0.980; p = 0.042) and maternal literacy (AOR = 3.098; 95%CI: 1.387–18.729; p = 0.021) were found to be significant predictors of acute respiratory infection among under five children.
