<s>[INST] What is the scale of the tuberculosis (TB) problem? [/INST] Although effective treatment has been available for over 70 years, tuberculosis (TB) remains the second leading cause of death from an infectious disease worldwide. The World Health Organization (WHO) estimates that more than one third of the world’s population is infected with Mycobacterium tuberculosis. TB continues to be a significant disease due to factors such as immigration, the emergence of drug resistant TB strains, HIV, and other conditions that weaken the immune system. Source: T-SPOT ASIA.
