World TB Day (24th March) commemorates the anniversary of Robert Koch’s 1882 discovery of the causative agent of tuberculosis (TB). Since then, it has been the subject of intense research, with hundreds of millions of dollars spent on TB research and development every year. Despite this, we still lack the antibiotics, vaccines and diagnostic tests needed to control the disease properly, and TB therefore remains a major public health challenge, particularly in developing settings like much of sub-Saharan Africa. As of last year, TB is the leading cause of death worldwide due to an infection.
