The number of polio cases has plummeted in the last 25 years, from 300,000 to less than 300. Even so, last May the World Health Organization declared that global eradication of polio, reaching that last 0.1 percent, was a “programmatic emergency for global public health.”

Zero cases of polio and smallpox, down from 16,000 and 29,000 cases earlier in the twentieth century. The number of measles cases has been reduced to 61, down from more than half a million in less than a century's time.
