Impact Of Seasonal Malaria Chemoprevention On Morbidity And Mortality Dues To Malaria Among Children Under Five Years In Chad.

In Chad, malaria remains the first cause of consultation with an annual morbidity of 35.39% and a mortality of51%. To reduce the burden of disease, Seasonal Malaria Chemo Prevention was adopted (SMC) in 2013.Since the adoption of SMC, no impact study was performed and no valuation model was proposed. The aim of this study was to model the impact of SMC on morbidity and mortality in children under five years in Chad. This was a prospective comparative study. Among the followed 8 health districts, a SMC program was applied on 4 in 2015. The impact of SMC was measured by the double-difference model on data from the Health Information System collected between January 1, 2011 and December 31, 2015. The incidence and mortality rate of malaria decreased globally between January 1, 2011 and December 31, 2015. The impact of SMC was a significantly increasing incidence of malaria by 1.587� and a decrease of mortality rate by 1.494 per 100 000. So, Seasonal Malaria Chemoprevention has contributed significantly to reduce severe malaria cases and frequentation of children aged between 3-59 months. Our results show that SMC contribute to fight malaria by increasing early frequentation of health center in case of simple malaria thus reducing the severe cases and the mortality.
