'Cascade of care' can help India plug gaps in TB treatment

Tuberculosis (TB) is the leading infectious cause of death globally. In 2015, WHO estimated that there were 10.4 million new TB cases worldwide. Six countries accounted for 60 per cent of the total burden, with India accounting for 27 per cent of the global cases. The WHO highlighted that about 4.3 million TB patients globally are "missed" by health systems annually and remain either untreated or unreported to national governments, which may undermine global efforts to combat TB. India alone has more than one million of these missing TB patients every year.
