Understanding Tuberculosis

The video discusses tuberculosis, a disease caused by Mycobacterium tuberculosis, which spreads through the air. It explains how the infection occurs, its symptoms, and progression. Not everyone infected shows symptoms immediately; it can remain dormant until the immune system weakens. If untreated, tuberculosis can be fatal, but it is treatable with antibiotics. The video emphasizes the importance of treatment to prevent deaths from this bacterial infection.
