After decades of effort, wild-type polio has been eradicated in Africa. The last confirmed case was recorded in Nigeria four years ago, and these days the ARCC (Africa Regional Certification Commission) has officially declared the disease eradicated in Africa.
The end result was made possible by a program in the state of Borno in Nigeria, where children were intensively vaccinated and the spread of the disease was monitored. The regional director of the African part of the World Health Organization said that it was a big and important feat with extreme perseverance, but after they had been close many times, the situation worsened again.
Until a few years ago, Nigeria was responsible for half of all cases of the disease. The only hotspots in the world remain Afghanistan and Pakistan.
