Surveillance des paralysies flasques aiguës en Côte d'Ivoire de 2007 à 2016 : importance et profil épidémiologique des entérovirus non poliovirus.

INTRODUCTION: Côte d'Ivoire's status as a polio-free country requires high quality surveillance of acute flaccid paralysis. Our study aims to determine the prevalence of non-poliovirus enteroviruses found in the surveillance of Acute Flaccid Paralysis (AFP) in Côte d'Ivoire and to study their distribution according to individual characteristics and associated factors. METHOD: We conducted an exhaustive descriptive and analytical cross-sectional retrospective study on 3597 cases of acute flaccid paralysis notified in the context of surveillance of AFP from 2007 to 2016 in Côte d'Ivoire. RESULTS: The mean annual rate of non-poliovirus enterovirus over the period was 11.3% over the study period with extremes of 9.2% and 15.9%. The absence of fever at the onset of illness and early age were factors associated with the occurrence of acute flaccid paralysis due to non-poliovirus enterovirus. CONCLUSION: Our study found a downward trend in non-poliovirus enteroviruses detected in AFP surveillance in Côte d'Ivoire, and identified the absence of fever and the age of the subject as being the factors associated with their occurrence. It is therefore necessary to type all cases of non-poliovirus enteroviruses detected in AFP surveillance to assess the risks of vaccine-derived polioviruses.
