Addressing social determinants to end tuberculosis.

Leave no one behind. This is the overarching pledge of the Sustainable Development Goals; a pledge that is far from being realised. In 2016, more than 4 million people with tuberculosis were estimated to be undiagnosed or their care and treatment were unknown.1 In the same year, nearly a fifth of the people who were diagnosed and known to be treated for tuberculosis had adverse outcomes, including 1·3 million deaths.1 One reason that millions of people affected by tuberculosis are left behind is an absence of coordinated, international action to combat poverty and inequality.
