<s>[INST] I had TB ten years ago – am I safe from it now? [/INST] TB treatment is very successful and is designed to kill all TB bacteria, provided that all the tablets are taken in the way the doctors instructed.

However, it is possible to catch TB more than once in your lifetime. TB is caused by exposure to TB bacteria, so if you breathe in this bacteria again at some later time, you may become ill again, especially if you have a weakened immune system. The best protection is to keep your immune system strong with nutritious food and a healthy lifestyle. Source: THE TRUTH ABOUT TB. Link: https://www.thetruthabouttb.org/talking-tb/questions-answers/.
