"There is no vaccine for guinea worm, and there are no drugs that can cure those who are infected. The pest once afflicted hundreds of millions of people from the Gambia to India. But the worm is now gone from Guinea, and from almost everywhere else. At last count, there were only five hundred and forty-two people infected, down from an estimated 3.5 million in 1986. Of the remaining cases, exactly five hundred and twenty-one are in South Sudan." -- Parasitologist Mark Siddall on the very successfull, Jimmy Carter sponsored campaign to eradicate the guinea worm
and how this campaign proved Malthus wrong.
