Nigeriaon Course to Becoming Polio-Free Chika Oduah ENUGU, NIGERIA - Nigerian activistAyubaGufwanmade sure his five children received polio vaccinations soon after they were born. "I was determined to make sure none of my kids got the polio virus because I am a victim myself," he said. Gufwancame down with polio when he was 5 years old. Forced to crawl on the floor, hewasn't able toattend school for years and faced ridicule. These days,Gufwanis a popular advocate for the needs of polio survivors. His organization has supplied more than 26,000 locally produced wheelchairs for Nigerians living with the disease. The government has been working with organizations such as UNICEF, Rotary International, the Bill and Melinda Gates Foundation, the World Bank and the U.S. Centers for Disease Control and Prevention to train health workers, procure the vaccine and spread awareness. This week, those efforts paid off. On Wednesday, Nigeria marked three years without a new case of wild polio virus. It's a status many say is a cause to celebrate, but Dr. UsmanAdamu, who helps coordinate the Nigerian government polio eradication operations center, offered a more measured response. "It's not a celebration per se,"Adamusaid. "It's just marking the milestone, which is significant in our quest to achieve eradication and, subsequently, certification." The next step for Nigeria to be certified polio-free will be rigorous surveillance to see that there are no further cases of the wild polio virus. Nigeria could be declared polio-free as soon as mid-2020. .
