Measurements fail to identify TB patients who could benefit from shorter treatment course
Tuberculosis (TB) is a difficult infection to treat and requires six months of multiple antibiotics to cure it. To combat the TB pandemic, a shorter and simpler drug treatment would be a huge advance since most TB occurs in resource-limited settings with poor public health infrastructures.
