"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.
What if a deadly epidemic was burgeoning and almost nobody noticed? In the latest issue of PLoS Neglected Tropical Diseases, a distinguished group of virologists, epidemiologists and infectious-disease specialists say that’s not a hypothetical question. They argue that Chagas disease, a parasitic infection transmitted by blood-sucking insects, has become so widespread and serious — while remaining largely unrecognized — that it deserves to be considered a public health emergency.

Screwworms, once the scourge of livestock (as well as pets and occasionally humans [link to VERY GRAPHIC slideshow]) throughout the Western Hemisphere, have been eradicated from the United States since 1966. In addition to constant vigilance by veterinary services and livestock handlers, who treated wounds immediately and set traps [link to 1920s informational film], the method which ultimately led to control of this horrifying pest is sterile insect technique. Maps showing the progress of the technique can be seen here. The USDA's National Agriculture Library maintains a special collection on the Screwworm Eradication Program. Here is a good overview of the problem and the USDA's solution, complete with (somewhat gruesome) pictures and videos. [more inside]
