In a post on the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, foundation Co-Chair Bill Gates writes about traveling to New York this week to deliver a speech to the U.N. on polio eradication, one of the top five global health priorities as described by U.N. Secretary-General Ban Ki-moon. “New polio cases are the lowest they’ve ever been and there are currently just three countries, down from 125 in 1988, where polio is still endemic: Afghanistan, Nigeria, and Pakistan,” Gates notes. He adds, “[T]he world is coming together with the financial resources, the political commitment, and the innovation necessary to do something absolutely extraordinary, to protect every child everywhere from this preventable disease” (9/25).
