2011 Annual Letter from Bill Gates: Ending Polio

Aid for the poorest has already achieved a lot. For example, because of donors’ generosity, we are on the threshold of ending polio once and for all. Polio is a terrible disease that kills many and paralyzes others. Fifty years ago it was widespread around the world. When you talk to people who remember polio in the United States, they’ll tell you about the fear and panic during an outbreak and describe grim hospital wards full of children in iron lungs that maintained their breathing. At its peak in the United States in 1952, polio paralyzed or killed more than 24,000 people.
As a result of mass mobilizations to administer the polio vaccine, polio was eliminated in the United States and most developed nations decades ago. Most people who live in rich countries assume the disease is long gone and that it doesn’t kill or paralyze children anymore. But it is still a frightening presence in a number of places around the world.

In 1988 the global community adopted the goal of ending polio altogether. At that time more than 350,000 children a year worldwide were killed or paralyzed by the disease. Since then, vaccination coverage has increased significantly and the number of cases has gone down by 99 percent, to fewer than 1,500 last year. There are now just four countries where polio transmission has never been stopped: India, Nigeria, Pakistan, and Afghanistan.

That’s incredible progress, but the last 1 percent remains a true danger. Eradication is not guaranteed. It requires campaigns to give polio vaccine to all children under 5 in poor countries, at a cost of almost $1 billion per year. We have to be aggressive about continuing these campaigns until we succeed in eradicating that last 1 percent.
Therefore, funding is critical to success. Organizations such as Rotary International http://www.rotary.org and the governments of India, the United States, the United Kingdom, and Japan are all major contributors to the polio campaign. Our foundation gives about $200 million each year. But the campaign still faces a 2011-12 funding gap of $720 million. If eradication fails because of a lack of generosity on the part of donor countries it would be tragic. We are so close, but we have to finish the last leg of the journey. We need to bring the cases down to zero, maintain careful surveillance to ensure the virus is truly gone, and keep defenses up with polio vaccines until we’ve confirmed success.
