Return of the Guinea Worm

The Guinea Worm is a nasty parasite that has almostNYT been eradicated.  But now, in one of the few remaining countries where it exists, Chad, it has started cropping up in dogs at alarming rates.  This may make ultimate eradication impossible.  This story is fantastic– a medical mystery, the interaction of poverty, infrastructure, and disease, how we treat our pets versus livestock animals, the life-cycle of a complex and nasty parasite.  Just give it a read.
