Wall Street Journal: Pulling the plug on polio eradication?

In counterpoint to the New York Timespositive coverage of the war on polio earlier this month, the Wall Street Journal on Friday put forward a case for abandoning the goal of eradication—and not just for polio. The Journal depicts a potentially seismic policy shift as emanating from the de facto leader of global health, Bill Gates.  Such a reversal is unlikely.

Gates got behind polio eradication in 1999 with a $50 million grant he believed would close out the disease. He predicted in 2000 that “If necessary resources and political will are devoted to polio eradication, the world can claim victory over this killer by the end of this year and certify the planet as polio free by the year 2005.” A decade and nearly a billion dollars later, the result is not eradication but oscillation, case numbers rising and falling.

Debate about the wisdom of the eradication policy has ensued. Millions of children die from malaria, for example, compared to which polio’s afflictions, although still horrible, are minute. More suffering could be averted, the argument goes, with a different allocation of global health dollars. The Wall Street Journal urges a move away from disease-specific campaigns and towards strengthening of overall health systems.

Polio might be expensive, but dropping eradication might be more so.  A Lancet study in 2007 concluded that control would be more expensive than eradication. But whatever the optimal policy, it requires funding. Eradication provides a sense of urgency and heroism; a control strategy does not.

Credibility is also at stake for global health advocates and Bill Gates in particular. Gates has backed not only getting rid of polio. In 2007, he and wife Melinda strong-armed a skeptical global health community to embrace malaria eradication. As hoped, tremendous energy and funding were released. A giant vogue for malaria eradication ensued, like Ashton Kutcher’s Twitter-driven campaign for bed nets. At the governmental level, the largest surge in funding commitments to battle malaria came one year after setting eradication as the goal. Arguably to protect these gains, the Gates Foundation doubled-down on polio eradication in 2008. And as the Wall Street Journal points out, Gates personally led the assault, descending in 2009 on the hottest polio spot, Nigeria, where vaccination lagged.

A resurgence of polio that came from consciously letting up on the disease, even if the best policy, would be a public relations disaster. The current trajectory also presents serious problems but far less severe: Eradication is expensive and doesn’t appear to be working. The solution has been continued mass dosing of the polio-vulnerable in the developing world and, for donor nations, a steady drip of good news that, yes, we are at the absolute cusp of eradication. Right now, the news is good in Nigeria and indeterminate in India, the familiar cusp yet again.

Ultimately, polio can be snuffed out by the downward pressure of eradication, the strengthening of health systems and much broader, slower and more costly development—improvements in food, water and sanitation.  In the near term, eradication will remain the strategy, but elusive.
