In the past 30 years, polio has moved from being a widely occurring infectious disease to one now on the brink of complete eradication. It is too soon to celebrate the success of what will be only the second infectious disease to be eradicated in human beings, after smallpox. But already the plans for ending the massive polio eradication programme and the consequences for the future of global health programmes and actors are being intensely debated.<\/span><\/p>\n

A recent high-level discussion at Chatham House, London focused on how the legacy of the polio eradication programme can strengthen health security and the drive towards universal health coverage (UHC). But to do so it will be vital for key elements and capacities to be integrated into health systems.<\/span><\/p>\n

Before the Global Polio Eradication Initiative (GPEI) was established in 1988, the wild poliovirus (WPV) was present in 125 countries, with approximately 1000 children being paralysed each day. In 2017, the world saw only 22 cases of polio caused by WPV, limited to just Afghanistan and Pakistan. However, the path towards eradication has not been straightforward. More than 99% of the reduction was achieved by 2000, but the last mile of eradication has proven to be the most difficult. As of 6 December, there have already been 28 confirmed WPV cases in 2018.<\/span><\/p>\n

Initiated by the pioneering efforts of Rotary International in the 1980s, the unique GPEI partnership has, to date, expended more than US$ 15 billion, much of it in low-income countries with weak health systems and low rates of routine immunization against a range of infectious diseases. It has achieved its progress through a focused campaign-based system of national and subnational supplementary immunization activities, training health workers\u2014including women who are from the communities they serve and therefore known and trusted\u2014to go door-to-door to find every child and provide drops of oral polio vaccine (OPV). To maintain OPV integrity, cold chains were established, along with managerial systems to manage and map the programme nationally and locally. A cornerstone of the programme is the operation of high-quality surveillance systems and laboratory networks to identify, confirm, and report every suspected case and undertake environmental monitoring of sewerage samples for evidence of circulating poliovirus. Emergency Operations Centres serve as hubs year-round and during immunization days and, in areas of conflict, on days of tranquillity. In many countries, the strength of this polio programme infrastructure has been of benefit to other health activities, including routine delivery of other immunization services and nutritional supplements such as vitamin A, as well as aiding rapid and efficient responses to emergencies such as natural disasters and outbreaks of diseases like Ebola.<\/span><\/p>\n

All these facets of the GPEI programme constitute an immensely valuable resource to strengthen countries\u2019 health systems and services. The polio assets can help build capacity for preventive approaches and primary healthcare services; and they are precisely the assets countries need to build and sustain resilience to health emergencies caused by infectious diseases, disasters, and disruptions.<\/span><\/p>\n

To translate this potential into effect, it will be necessary to transition the polio assets presently operated and funded by the GPEI into country ownership and integrate them into health systems. And therein lies a great challenge. Countries will need the financial resources to increase their health spending and the political will to prioritise investment in health in the face of competing areas of national expenditure. They can be assisted by development partners, including the UK, which has been one of the largest contributors to the GPEI.<\/span><\/p>\n

The arguments in favour are clear. The necessary investments will:<\/span><\/p>\n
