Surging cases in Pakistan and Africa have dashed hopes of defeating the virus this year.
Summary
The global initiative to eradicate polio is badly stuck, battling the virus on two fronts. New figures show the wild polio virus remains entrenched in Afghanistan and Pakistan, its other holdout, where cases are surging. The main problem in both countries is that the massive vaccination campaigns held every few months are still not reaching every child. In Africa, meanwhile, the vaccine itself is spawning virulent strains that are hard to contain. The leaders of the world’s biggest public health program are admitting for the first time that success is not just around the corner—and intensively debating how to break the impasse.
