Evaluation du système de surveillance épidémiologique de la fièvre jaune dans le district sanitaire de Kadiolo, 2020

Abstract

Yellow fever is an acute hemorrhagic disease of viral origin caused by a flavivirus transmitted between humans, via domestic mosquitoes belonging to the Aedes species or transmitted to humans from the reservoir constituted by primates. The fatality rate is between 25% and 50%. The preventive measures available to countries have largely proven their effectiveness. The WHO estimates that 200,000 cases of yellow fever and 30,000 deaths from the disease worldwide are estimated to be 200,000 each year. Africa is the most affected continent, with 95% of cases recorded worldwide. In Mali, on December 5, 2019, the Government of Mali officially declared an outbreak of yellow fever in the regions of Sikasso and Koulikoro. It is in this context that we conducted a descriptive cross-sectional study from January 01, 2020 to December 31, 2020 on data from the epidemiological surveillance of yellow fever for the year 2020. The epidemiological surveillance indicators evaluated were very good overall. The general objective was to evaluate the yellow fever epidemiological surveillance system from January 1, 2020 to December 31, 2020 in the Kadiolo Health District. Keywords: Evaluation, Epidemiological Surveillance, Yellow Fever, Kadiolo.Yellow fever is a notifiable disease. It is likely to cause epidemic outbreaks with high mortality. The fatality rate can vary between 25% and 50%. The World Health Organization (WHO) estimates the number of cases at 200,000 each year, with the majority on the African continent. The preventive measures available to countries have largely proven their effectiveness. In Mali, on December 5, 2019, the Government officially declared an outbreak of yellow fever in two highly populated regions of the country, Sikasso and Koulikoro. It is in this context that we conducted this descriptive cross-sectional study. The general objective was to evaluate the yellow fever epidemiological surveillance system from January 1, 2020 to December 31, 2020 in the Kadiolo Health District. The evaluation of the epidemiological surveillance system for yellow fever in the health district of Kadiolo made it possible to verify the capacities of this district to deal with the occurrence of possible outbreaks. The epidemiological surveillance indicators assessed were good overall
