TB Sanitariums were also used for isolating TB cases for a lot of years. There were no cures prior to antibiotics except to remove an infected lung lobe.
It looks like we're in danger of entering another era where the word "Tuberculosis" will again connote "The White Plague".
A nursing home I worked in for a while during the mid 1980's was an old TB hospital used by the state that was converted to a nursing home later. The top floor ward still had active TB patients there. Once you get TB you have to be monitored the rest of your life. Inactive TB can become active at any time. The older strain isn't as easy to catch as you would think with some basic precautions though. Not knowing someone has it is the danger.
The new strain though sounds like real bad news. Some of it comes from improper treatment where patients had it and only took about half the MEDS etc till they felt better and the bug grew immune to the treatment in some cases.
