What's the Link Between Sleeping Sickness and Unwanted Facial Hair?

Graham at Gross Anatomy has an interesting riff on how Eflornithine, a promising drug that cures African sleeping sickness, has been repurposed for a much more lucrative life. Sleeping sickness, Graham reminds us, is caused by a protozoan infection delivered by the bite of a tsetse fly.

UPDATE: Medecins Sans Frontieres announced a project to test a new, unnamed drug to combat sleeping sickness. It will replace the currently used, also unnamed medication: "an arsenic-based compound, which has a potential mortality rate of 10% and was developed over 50 years ago."
