For years, the World Health Organization's polio goal has been to declare it conquered and eliminated worldwide, but a slight glitch in the plan has caused the WHO to instead declare polio a public health emergency.
The glitch is that it's the vaccine that's causing the disease spike. The WHO's polio emergency committee met January 25, 2023.
"Though cVDPV2 (circulating vaccine-derived polioviruses) cases are declining, the risk of international spread remains high due to transmission in Africa, detections in the Americas, Europe, and Israel, and a recent detection in Indonesia. The group also raised concerns about cVDPV1, the vaccine-derived type 1 strain, in Africa, especially against the backdrop of WPV1 cases in Mozambique and population immunity gaps," CIDRAP reported.
