The International Health Regulations' Emergency Committee, responsible for assessing global poliovirus spread, has expressed concerns over Pakistan's efforts to reach a large number of children through its polio eradication campaign, warning that failure of the polio programme in Afghanistan poses a serious threat to Pakistan, reported 24NewsHD TV channel.
In a session convened by the World Health Organisation (WHO) director general on August 16, 2023, the committee highlighted the gaps in Pakistan and Afghanistan's efforts to eliminate polio disease. It emphasised that recent favorable environmental samples from Peshawar and Karachi underscore the persistent risk of a polio outbreak in the country.
The committee highlighted that a new case of WPV1 emerged in Pakistan since the last meeting, bringing the 2023 total to two cases. Both instances occurred in the Bannu district of Khyber Pakhtunkhwa. Throughout the year, at least 15 environmental surveillance-positive samples were identified.
"Although the action plan in southern KP has resulted in 160,000 more children being vaccinated, the context remains challenging — including political instability, insecurity in some areas with front-line workers requiring police patrols to accompany them and vaccination boycotts, where communities make demands for other services in exchange for allowing polio vaccination," the committee further said.
In Afghanistan, since the last meeting, there have been five new WPV1 cases reported, all from Nangarhar province, the emergency committee said adding that the cases occurred in five different districts and had onsets from April to May 2023. “Any setback in Afghanistan poses a risk to the programme in Pakistan due to high population movement,” the emergency committee warned.
The committee further observed that in 2023, there were only two genetic clusters of WPV1 identified, compared to three in 2022 and five in 2021.
However, there have been multiple chains of transmission within these two genetic clusters, detected primarily in the endemic zones of Eastern Afghanistan and South KP of Pakistan, including an extreme orphan virus, indicating some gaps in surveillance.
The emergency committee warned that due to the ongoing transmission in eastern Afghanistan with cross-border spread into Pakistan and the large pool of unvaccinated zero-dose children in southern Afghanistan constitutes an ongoing risk of WPV1 re-introduction into the southern region.
