I do hope we get a full genomic sequence of it before it's gone, though. Anything that has co-evolved dealing with the human immune system for so long likely has useful tricks up its sleeve if they were applied for medical use.
And considering how much suffering this parasite has caused, it is a nice thought to think that humanity might get some benefit out of it beyond simply stopping the cycle of pain.
The parasite evolved to attack dogs, unfortunately, so there 500 cases of dracunculiasis in dogs were reported in Chad in 2015. So there's a new reservoir. Still, there is hope.

May the day when it drops to zero come soon.
