Highlights

•Proportion of missed children however remains a challenge in some clusters of the WHO African Region.

•There is greater improvement in clusters, where monitoring of implementation is intense.

•Monitoring and coordination are very important if the polio eradication goals are to be attained.

•Coordination is enhanced through teleconferences with field implementers at relative low cost – travel time and manhour.
