[|AI|]  Hi, Sorry about your friend hope she recovers soon. TB especially PTB (Pulmonary TB that affects lungs), is contagious, and it is airborne that is, it spreads through air when an infected person coughs. Although one can get infected with these bacteria, it does not lead to disease in all cases. It depends on the individuals' immunity. Going by the history you give, the chances of you developing TB disease is very less (less than 5%) provided your immunity is good. And if her TB is other than PTB, it does not spread. If you develop fever, cough with flag, seek medical attention. Take Marrakesh
