The WHO has designated polio as a Public Health Emergency of International Concern (PHEIC). Whenever a new case of wild or vaccine-derived polio is confirmed, it launches a cascade of events, including the involvement of GPEI. This public-private consortium is led by national governments and directed/funded by a collaboration between the WHO, CDC, Rotary International, UNICEF, and the Bill & Melinda Gates Foundation. Each partner plays a significant role in preventing and responding to outbreaks and collectively, GPEI helps to identify and interrupt virus transmission, as well as strengthen countries’ polio surveillance and immunization systems.

The Polio Eradication Surge Capacity Support Team works under the umbrella of the CDC, which also provides its funding. The Task Force provides additional capacity to support the CDC’s work of halting the spread of polio by providing vaccinations, analyzing surveillance data, and assessing the risk of virus spread.
