Implication

Afghanistan's 2020 polio surge signals stalled eradication; leaves open optimal strategies for cVDPV2 control in conflict zones.

Structured PICO

Population

Children in Afghanistan, specifically those aged <5 years targeted for vaccination, and those aged <15 years for acute flaccid paralysis surveillance.

Intervention

Polio eradication efforts including routine immunization, supplementary immunization activities (SIAs) with oral poliovirus vaccine (OPV), and environmental surveillance.

Outcome

Number of wild poliovirus type 1 (WPV1) and circulating vaccine-derived poliovirus type 2 (cVDPV2) cases detected.

Despite political instability and the COVID-19 pandemic, polio cases in Afghanistan decreased significantly in 2021, highlighting the potential for eradication with resumed nationwide vaccination efforts.

Limitations

Accuracy of the reported coverage data and LQAS surveys data is uncertain because many of these are reported by inexperienced officers selected by the de facto government without other oversight.
Quality of AFP surveillance likely suffered since the beginning of the COVID-19 pandemic and might also remain reduced from potential disruptions since the transition in government.
