poliovirus outbreaks currently still occur around the world and American children continue to receive polio vaccinations. Dr. Bruce Aylward, Director of the Global Polio Eradication Initiative at the World Health Organization, stated that, "as we stand on the brink of eliminating wild polioviruses around the world, these results provide a glimpse of the massive economic benefits of global polio eradication." To date, the Global Polio Eradication Initiative has succeeded in reducing the annual cases of paralytic polio from an estimated 350,000 cases in 1988 to less than 2,000 cases in 2006. The only remaining areas of the world that have not yet disrupted transmission include regions in four countries (Afghanistan, India, Nigeria, and Pakistan).
