World Polio Day is this month and we are facing a major challenge. The news out of Afghanistan and Pakistan tells us that we have more work to do. It tells us that polio will not die out quickly or easily.Most of all, it tells us that we are needed now more than ever. Success will require us to remain steady and show that there is no time limit to our commitment. We are in this to the end, and we will conquer this terrible disease. We will give life back to children and families, and restore hope to communities.
