Why member states must renew recommitment to eradication of polio – WHO


Dr Matshidiso Moeti


The World Health Organisation (WHO) has called on the governments of nations to work together toward ensuring the eradication of polio by end of 2019 or early 2020 adding that the African Region has confirmed continued emergence of circulating vaccine-derived polioviruses (cVDPVs) in some Member States, attributed to weak routine immunization services delivery.

WHO Regional Director for Africa, Dr Matshidiso Moeti who made the call in her message on World Polio Day, on Wednesday, in Abuja said there is need to strengthen surveillance efforts in the African region noting that some countries have sub-optimal surveillance, in both secure and insecure areas.

While expressing concern that it would be a disaster if the African Region is not certified as a result of poor surveillance performance, she urged all countries to recommit to strengthen surveillance urgently.

“We are close to ending polio, I call on all countries to work together to ensure that this becomes a reality, and the African Region is declared to have eradicated polio by end 2019 or early 2020,” she stated.

While describing polio as “an incurable but completely vaccine preventable disease that still threatens children in a few places around the world,” the Regional Director explained that the World Health Organization joins millions of people around the world to observe World Polio Day on October 24th every year, adding that the global body aims to galvanize support to end polio.

Discussing the enviable progress made to end polio, she said: “Since the launch of the Global Polio Eradication Initiative (GPEI) nearly 30 years ago, new cases of polio have dropped by more than 99.9 percent – from 350,000 cases every year in more than 125 affected countries, to 22 wild polio cases in 2017 in two affected countries.”

She said the African Region has made tremendous progress towards polio eradication. “As late as 2012, the Region accounted for more than half of the global polio burden, but polio cases have dropped steadily from 128 cases in 2012, to 4 cases in 2016 to 0 cases in 2017 and 2018. The African Region has now reached an important milestone towards eradication – it has been more than two years since the last case of wild poliovirus.”

“I applaud the excellent efforts of governments, polio eradication partners, communities, parents and health workers in achieving this magnificent milestone.”

“However, this is no time to be complacent. Until polio is eradicated, all countries remain at risk of outbreaks. As a Region, Africa can only be certified to have eradicated polio if three years have passed without any confirmed wild poliovirus, and if polio surveillance (closely looking out for polio cases) has been maintained at the level required for certification. If no new case is confirmed, and surveillance is quickly strengthened, the African Region can be certified to have eradicated polio by the end of 2019 or early 2020.”

She recalled that at the 71st World Health Assembly (WHA) in May 2018, she tasked Member States to implement containment of polioviruses and potential polioviruses infectious materials according to the global action plan (GAP III), in a timely manner, to avoid any leakage of polioviruses into the environment and populations which could result in catastrophic outbreaks and reverse the gains towards eradication. She disclosed that the progress on polioviruses containment by Member States will be presented at the next WHA in May 2019.

“In 2017, the Addis Ababa Declaration on Immunization was endorsed by Heads of State at the African Union. It called for governments to invest further in immunization services which are key for stopping emergence of cVDPVs, sustaining the gains towards polio eradication and post certification of polio eradication. Eradication of polio needs political commitment and adequate resources. WHO assures all Member States of its dedicated support.”
