Pretomanid was approved by the FDA today. Obviously the molecule and treatment protocol has been in design and study for years up to this point, but FDA approval is a reasonable endpoint to celebrate as a "cure being discovered." I suppose you could also argue it's "not a cure" because in the small trail performed it only cures 90%. Finally, I don't know what you're getting at with "not a more deadly strain". XDR TB is "eXtensively Drug Resistant" which makes it also the most fatal form of TB. There are a lot of things which left untreated can kill you. I assume it is normal for fatality rates of a strain of disease to be stated as the post-treatment fatality rate.
