Via Jezebel: ‘The Western medical discourse on Africa has never been particularly subtle: the continent is often depicted as an undivided repository of degeneration. Comparing the representations of disease in Africa and in the West, you can hear the whispers of an underlying moral panic: a sense that Africa, and its bodies, are uncontainable. The discussion around Ebola has already evoked—almost entirely from Tea Party Republicans—the explicit idea that American borders are too porous and that all manners of perceived primitiveness might infect the West.

And indeed, with the history of American and European panic over regulating foreign disease comes a history of regulating the perception of filth from beyond our borders, a history of policing non-white bodies that have signified some unclean toxicity.’
