We are so close. We’ve got a 99.9 percent reduction in polio. But we’re not there, yet,” says John Sever, a vice chair of Rotary’s International PolioPlus Committee, who has been part of the eradication effort since the beginning. “Rotarians and others have to keep working. People will naturally say, ‘Well, it seems to be basically gone, so let’s move on to other things,’ but the fact is, it isn’t gone, and if we move on and don’t complete the job, we set ourselves up for having the disease come right back.
