T.B is never cured, the first line drug just make it dormant, and second line drugs are there if the bacteria resists the first line. after that no cure and you die
i recommend you guys read Mountains Beyond Mountains, the Quest of Dr. Paul Farmer by Tracy Kidder. Absolutely my favorite book, great motivator about this docter, paul farmer, who goes on to change the cdc and who's whole treatment of tb when he shows in experiements in haiti, peru, rwanda, and russia that the current drugs are contributing to more drug resistant tb and turning it into killer bacteria
they'll probably send dr. farmer to this guy right now in denver.
