Résumé

Background: Acute poliomyelitis has been the ground for several epidemic outbreaks over many years and caused high mortality
as well as permanent acute flaccid paralysis. However, the disease is under control nowadays thanks to a well elaborated
surveillance strategy. The objective of this study is to evaluate the epidemiologic surveillance system for acute flaccid paralysis
in the Bogodogo health district from 2016 to 2018. Methods: We conducted a cross-sectional evaluation with a quantitative
approach over a period of 3 years going from January 1st 2016 to December 31st 2018. Based on the collected data, we estimated
the surveillance indicators of the world health organization and the Atlanta Center for Disease Control. The analysis of indicators
and surveillance delays did allow the assessment of quality and performance of the surveillance system. Results: During our
study time in the Bogodogo health district, we recorded 45 suspected cases of acute flaccid paralysis. The key performance
indicators, except for two of them (Proportion of samples that were collected in the laboratory within 72h after collection and
proportion of active surveillance reports received) were meeting the criteria of the world health organization. The sensitivity and
the positive predictive value were respectively of 94% and 100%. However, the laboratory results were incomplete, only
representing 18% of cases, and the mean delay for sample transport to the laboratory was of 11 days which was out of normal
range according to the world health organization. Conclusion: Our results show a satisfying global performance of the
surveillance system in the Bogodogo district, but the implementation of our recommendations will help improve the current
