Performance and utility of the Acute Flaccid Paralysis surveillance system in Niamey (2005-2016): Documentary analysis and perception of stakeholders.

Abstract

Introduction :
Poliomyelitis is a highly contagious viral disease that primarily affects children under 5 years of age. The quality of surveillance makes it possible to detect or not the Polio virus circulating in a country. The objective was to evaluate the performance and utility of the Acute Flaccid Paralysis (AFP) surveillance system in Niamey through documentary analysis and the perception of stakeholders (2005-2016).

Methodology :
This was a cross-sectional survey that collected data from 2005 to July 31, 2016. It involved the stakeholders involved in AFP surveillance in the Niamey region. The non-polio AFP rate and the proportion of stool samples collected within 14 days were used to select the health facilities. Sociodemographic variables and the CDC AFP surveillance attributes were studied.

Results :
a total of 123 actors were interviewed, 85 were nurses, 12 were community relays, and 8 were traditional practitioners. AFP surveillance was integrated into the organizational chart along with other surveillance activities, i.e., 100%. On average, 3±0.7 people per CSI were involved in surveillance, with 97% providing training on surveillance. Information was disseminated to 100% of CSIs. Investigation of AFP cases was decentralized in 94% of cases. By 2015, 163 cases of AFP had been identified, including 68 (41.72%) indigenous cases and 95 (58.28%) imported cases.

Conclusion :
Although complex, the AFP surveillance system in Niger proves its utility. It is acceptable, reactive, and representative, granting the country "polio-free" status.
