Statement of the Thirtieth Polio IHR Emergency Committee
23 November 2021
The thirtieth meeting of the Emergency Committee under the International Health Regulations (2005) (IHR) on the international spread of poliovirus was convened by the WHO Director-General on 3 November 2021 with committee members and advisers attending via video conference, supported by the WHO Secretariat. The Emergency Committee reviewed the data on wild poliovirus (WPV1) and circulating vaccine derived polioviruses (cVDPV). Technical updates were received about the situation in the following State Parties: Afghanistan, China, Guinea Bissau, Mauritania, Nigeria, Pakistan, Senegal and Ukraine.

Although heartened by the apparent progress, the Committee unanimously agreed that the risk of international spread of poliovirus remains a Public Health Emergency of International Concern (PHEIC) and recommended the extension of Temporary Recommendations for a further three months. The Committee recognizes the concerns regarding the lengthy duration of the polio PHEIC but concluded that there are still significant risks despite apparent progress made in the two endemic countries, and that the coming three months would be a critical period to monitor the situation there closely.

…Additional Considerations
The committee noted the convincing efforts by China to rule out further transmission and accepted that nine months after the last detection of cVDPV3, China was no longer infected.
The Committee welcomed the further progress achieved with the introduction and delivery of nOPV2 but was concerned to hear of significant delays in outbreak response timelines as countries opted to delay response in order to use nOPV2. Polio outbreaks should continue to be met with an aggressive and timely response with the immediately available type-2 vaccine.
The Committee warned of the ongoing effects of COVID-19 particularly on essential immunization and possible future disruptions of supply and delivery of vaccines. Zero-dose children and communities were missed before the advent of the pandemic and it is critical that these children and communities are prioritized as essential immunization services are restored. COVID-19 is likely to continue to have adverse effects on all health programs and systems for some time to come so the polio programme must continue to manage its response to overcome the remaining hurdles.
Based on the current situation regarding WPV1 and cVDPV, and the reports provided by affected countries, the Director-General accepted the Committee’s assessment and on 5 November 2021 determined that the situation relating to poliovirus continues to constitute a PHEIC, with respect to WPV1 and cVDPV. The Director-General endorsed the Committee’s recommendations for countries meeting the definition for ‘States infected with WPV1, cVDPV1 or cVDPV3 with potential risk for international spread’, ‘States infected with cVDPV2 with potential risk for international spread’ and for ‘States no longer infected by WPV1 or cVDPV, but which remain vulnerable to re-infection by WPV or cVDPV’ and extended the Temporary Recommendations under the IHR to reduce the risk of the international spread of poliovirus, effective 5 November 2021.
