Nigeria marks three years without a wild polio case, meaning Africa could be declared free of the disease in 2020
Africa is on the verge of being declared polio free, after three years without any recorded cases of the disease, according to the World Health Organization (WHO).
Nigeria marked three years without a wild polio case on Wednesday, a “major milestone”. If no more incidences emerge in the next few months, Africa could officially be declared polio free in 2020. The last case was recorded in Borno state in August 2016.
