The problem is that TB, while not particularly contaigous, is a slow indolent infection that can remain dormant for years. Many people are exposed but do not develop TB because they develop immunity. Some are exposed and only develop active disease years later.

The major problem with this strain is it's resistance to treatment. Normal TB is treated with two or three different medications for a period of 9 months. Thats how hard the normal TB is to kill.

TB is particularly dangerous in immune compromised individuals. It's common in the prison system and in many South East Asian countries.
