Polio Eradication Proves Difficult

There is an story today in the New York Times about the uphill battle to eradicate polio from the earth.

Nearly 18 years ago, in what they described as a "gift from the 20th century to the 21st," public health officials and volunteers around the world committed themselves to eliminating polio from the planet by the year 2000.

Since then, some two billion children have been vaccinated, cutting incidence of the disease more than 99 percent and saving some five million from paralysis or death, the World Health Organization estimates.

But six years past the deadline, even optimists warn that total eradication is far from assured. The drive against polio threatens to become a costly display of all that can conspire against even the most ambitious efforts to eliminate a disease: cultural suspicions, logistical nightmares, competition for resources from many other afflictions, and simple exhaustion. So monumental is the challenge, in fact, that only one disease has ever been eradicated — smallpox. As the polio campaign has shown, even the miracle of discovering a vaccine is not enough.

Not least among the obstacles is that many poor countries that eliminated polio have let their vaccination efforts slide, making the immunity covering much of the world extremely fragile, polio experts warn. They compare it to a vast, tinder-dry forest: if even one tree is still burning, a single cinder can drift downwind and start a fire virtually anywhere.

The article focuses on problems in Nigeria and India. It's worth reading and will hopefully, at the least, renew your sense of graditude for modern medicine/science.
