Will you give your kids the Polio vaccine if you knew that it could help eradicate it worldwide and finally rid us of this dreaded disease?
Why Can't the World Eradicate Polio? | Newsweek International | Newsweek.com
In the universe of global diseases, polio would seem to be a minor problem. Fewer than 2,000 people in the world were stricken last year. AIDS and malaria, by contrast, killed more than three million people. In a list of the world's most threatening infectious diseases, polio would rank pretty far down—past measles, meningitis, influenza and drug-resistant tuberculosis, to name a few. Which raises the question: why did
Bill Gates release $255 million of his foundation's money on Wednesday to fight polio?
The answer many health officials give is that polio is on the brink of being eliminated once and for all. A campaign of mass inoculations around the world, led by the World Health Organization, has reduced cases by 99 percent, cornering the disease in a few pockets of resistance. What's needed, health officials argue, is an infusion of funds to get them over the hump.
Trouble is, it's not clear that more money is going to do the trick. It's not easy to wipe a disease off the face of the planet—especially one like polio, which spreads easily and quickly through contact and occasionally through contaminated food and water. Only one in 200 children who contract the virus shows symptoms (usually paralysis), which makes the other 199 silent carriers. Indeed, more than two decades of fighting the disease around the globe has taught health workers that it is far more stubborn than originally thought. The failure to deliver the knockout blow has cast doubt on whether eradication is a viable strategy in the war on polio—even with a donor as bold and wealthy as Gates.
