DDT and the malaria wars

Sat, 2006-09-16 12:47 -- John Hawks

I'll be lecturing on hemoglobinopathies again this week, and I stumbled across this 2001 article by Malcolm Gladwell, profiling Fred Soper and the early 20th century effort to eradicate malaria.

This passage is from a longer section describing his work eliminating invasive Anopheles gambiae from Brazil in 1938:

Four thousand men were put at his disposal. He drew maps and divided up his troops. The men wore uniforms, and carried flags to mark where they were working, and they left detailed written records of their actions, to be reviewed later by supervisors. When Soper discovered twelve gambiae in a car leaving an infected area, he set up thirty de-insectization posts along the roads, spraying the interiors of cars and trucks; seven more posts on the rail lines; and defumigation posts at the ports and airports. In Soper's personal notes, now housed at the National Library of Medicine, in Bethesda, there is a cue card, on which is typed a quotation from a veteran of the Rockefeller Foundation's efforts, in the early twentieth century, to eradicate hookworm. "Experience proved that the best way to popularize a movement so foreign to the customs of the people . . . was to prosecute it as though it were the only thing in the universe left undone." It is not hard to imagine the card tacked above Soper's desk in Rio for inspiration: his goal was not merely to cripple the population of gambiae, since that would simply mean that they would return, to kill again. His goal was to eliminate gambiae from every inch of the region of Brazil that they had colonized--an area covering some eighteen thousand square miles. It was an impossible task. Soper did it in twenty-two months.

There were the great successes, and some hubris, and something of a tragic end. But it's a timely story, considering that WHO has stepped up its recommendations to use DDT to fight malaria in Africa. (via Instapundit)

And Soper was a Kansas boy.

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
