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.
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.
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.
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.
科特迪瓦作为无脊髓灰质炎国家，需要对急性弛缓性麻痹进行高质量监测。我们的研究旨在确定在科特迪瓦急性弛缓性麻痹（AFP）监测中发现的非脊髓灰质炎肠道病毒的流行情况，并根据个体特征和相关因素研究其分布。
我们对2007年至2016年在科特迪瓦AFP监测背景下报告的3597例急性弛缓性麻痹病例进行了详尽的描述性和分析性横断面回顾性研究。
在研究期间，非脊髓灰质炎肠道病毒的年均发病率为11.3%，极端值为9.2%和15.9%。发病时无发热和低龄是与非脊髓灰质炎肠道病毒导致急性弛缓性麻痹发生相关的因素。
我们的研究发现，在科特迪瓦AFP监测中检测到的非脊髓灰质炎肠道病毒呈下降趋势，并确定无发热和患者年龄是与其发生相关的因素。因此，有必要对在AFP监测中检测到的所有非脊髓灰质炎肠道病毒病例进行分型，以评估疫苗衍生脊髓灰质炎病毒的风险。
