Background: Acute infectious diarrhea is still one of the most important causes of death in childhood and malnutrition increases its morbidity and mortality. There is a strong correlation between the nutritional status of the child and the risk of subsequent diarrhea. Micronutrient deficiencies also increase the childs susceptibility to diarrhea and vitamin A and zinc supplementation has been shown to reduce the incidence and hasten recovery from acute diarrhea episodes. Results: Fifty-eight (27%) of these children developed a new diarrhea episode during the follow up period. Children who were vitamin A and zinc deficient at the time of admission, above 12 months of age, kept animals at home or had weight-for-age and weight-for-height z scores <-1 during the univariate analysis had a higher risk of experiencing subsequent diarrhea. Vitamin A and zinc deficiencies, keeping animals at home, diarrhea duration ? 4 days on enrolment and weight-for-age z score <-1 reminded as independent risk factors during multivariate analysis. The aggregation of these factors had a synergistic effect on the risk of subsequent diarrhea. Conclusion: Children with micronutrient deficiencies and in contact with animal had the highest risk of suffering subsequent diarrhea. Our findings support the current approach of providing multiple micronutrient supplements for the prevention of infection in order to reduce mortality in children.
