Key result
Between 2016 and 2021, Niger reported 4,134 AFP cases in children under 15, with an annualized non-polio AFP rate averaging 5.93 per 100,000, and identified 33 cases of circulating vaccine-derived poliovirus type 2.
Why the study?
Niger experienced circulating vaccine-derived poliovirus outbreaks in 2018, highlighting the need to comprehensively assess acute flaccid paralysis surveillance trends, patterns, and challenges.
Population
4,134 acute flaccid paralysis cases under 15 years old in Niger
Design
Nationwide surveillance study

AFP surveillance in Niger meets most targets yet shows gaps in specimen quality and transport; leaves open how to optimize systems in conflict settings.
Observational (n=4,134)
Yes
Continued AFP surveillance in Niger demonstrates adequate detection rates but highlights the need for improved stool specimen quality and transportation times to support polio eradication.
Ishagh et al. (2025) conducted an observational in Acute Flaccid Paralysis (n=4,134). Acute Flaccid Paralysis (AFP) surveillance was evaluated on Annualized non-polio AFP rate per 100,000 population < 15 years. Between 2016 and 2021, Niger reported 4,134 AFP cases in children under 15, with an annualized non-polio AFP rate averaging 5.93 per 100,000, and identified 33 cases of circulating vaccine-derived poliovirus type 2.
