Statement on stopping wild poliovirus transmission in Afghanistan and Pakistan


Acknowledging that our common goal is to attain ‘Health for All by All’, which is a call for solidarity and action among all stakeholders; 

Noting the progress achieved globally in eradicating wild poliovirus transmission since 1988, with endemic wild poliovirus transmission restricted to just two countries – Afghanistan and Pakistan; 

Recalling that 2023 is the target year for interrupting all remaining poliovirus transmission globally, as per the Global Polio Eradication Initiative Strategy 2022–2026: Delivering on a Promise; 

Appreciating the recent, intensified efforts made by both Afghanistan and Pakistan, resulting in a unique epidemiological window of opportunity to achieve success in 2023, as characterized by:

the geographic restriction of wild poliovirus transmission in 2022 to eastern Afghanistan and a few districts of north-western Pakistan;

the absence of any wild poliovirus case since September 2022; 

the significant decline in genetic biodiversity of wild poliovirus to just a single lineage in each country; and

the successful interruption of circulating vaccine-derived polioviruses;
