Following the recent detection of wild poliovirus in Nigeria, Ministers of Health from Cameroon, Central African Republic, Chad, Niger and Nigeria have declared the polio outbreak in Nigeria as a public health emergency for countries of the Lake Chad basin. The declaration, coming out of the 66th session of the WHO Regional Committee for the African Region, demonstrates commitment from governments across the region to bolster momentum in the fight against the virus.

Nigeria has mobilized its immunization forces and will look to take heed of four key lessons earned during almost three decades of anti-polio efforts: 1) establishing and sustaining trust is critical to the success of eradication campaigns; 2) frequent, independent monitoring and evaluation are key to tracking the progress of an intervention and making modifications; 3) holding all actors accountable is essential to pushing an intervention forward and; and 4) contextualized health initiatives are key in fighting polio and other diseases. These lessons will reinforce a cohesive, multilateral strategy that builds on past successes to secure a polio-free Nigeria. (Center for Global Development, 16 Nov 2016)
