Why we need new interventiosn for TB

From Cornell University: Each year, tuberculosis kills nearly two million people while an estimated nine million develop the disease, including 450,000 new cases of multidrug-resistant TB, including people recently diagnosed with particularly lethal new resistant strains. today's standard TB treatment were developed in the 1950s and 1960s, and the most commonly used TB test — developed more than a century ago — manages to detect TB in only about half of the cases.
