Nigeria was declared polio-free in August 2020, a feat it achieved after several decades of continuous action. In 2009 Nigeria was considered the epicentre of a worldwide outbreak of the polioviruses. And in 2016, the country was temporarily declared polio-free. However, three new cases soon emerged in Northern Nigeria. This was a major setback in the fight against polio as these cases were the first to be discovered since 2014.
