Two years after Nigeria celebrated the eradication of new infection of poliomyelitis in the country, the federal government has confirmed the re-occurrence of the disease with two new cases in Borno state.
The development is seen as a major setback for Nigeria, which was on track to be declared polio free in 2017.
Polio is an infectious viral disease that usually affects children. It can only be prevented through immunisation. The disease is spread by poor sanitation and contaminated water.
This development is as result of Boko Haram terrorist group attacks on polio centres and medical officials which has stalled the polio eradication programme in Borno and some other areas of the north-east.
