Why the study?

The COVID-19 pandemic disrupted polio vaccination and surveillance activities worldwide in 2020, requiring an updated summary of surveillance performance indicators.

Population

43 priority countries

Comparison

Surveillance performance indicators in 2020 vs 2021

Design

Surveillance performance report

Discussion

Member takes

Implication

Alerts clinicians to re-emergence risk in certified regions; leaves open surveillance and response adequacy.

Structured PICO

Population

43 priority countries experiencing or at high risk for poliovirus transmission, focusing on acute flaccid paralysis (AFP) surveillance among persons aged <15 years

Intervention

Poliovirus surveillance (AFP surveillance and environmental surveillance)

Outcome

Surveillance performance indicators (nonpolio AFP rate and collection of adequate stool specimens)

National AFP surveillance performance improved from 2020 to 2021 in many priority countries, but substantial national and subnational gaps persist, highlighting the need for continued monitoring to achieve polio eradication.

Limitations

Inaccurate estimates of populations could affect AFP surveillance and limit interpretation of surveillance indicators
High NPAFP rates do not necessarily indicate highly sensitive surveillance
Accuracy of stool specimen adequacy depends on whether the field investigator can elicit an accurate paralysis onset date
