India has the world’s highest share of TB and drug-resistant TB cases
As old as known history, Mycobacterium tuberculosis, the bacillus that causes TB, remains common and deadly. TB caused 3.4% of all deaths globally in 1990 and 2.12% in 2017, according to the University of Washington’s Global Burden of Disease report, 2017. The disease affected 10 million--of whom 558,000 had drug-resistant TB--and killed 1.6 million globally in 2017, according to the WHO’s Global Tuberculosis Report (GTR), 2018.
India has the world’s highest share (27%) and over a quarter of all TB cases at 2.7 million, and accounted for 32% (421,000)--nearly a third of all TB deaths--in 2017, according to the report. An estimated 2.79 million TB patients are added annually, according to the ministry of health and family welfare’s (MoHFW) National Anti-Tuberculosis Drug Resistance Survey, 2016. India also has the highest share (24%) of drug-resistant TB cases--around 135,000 in 2017--of whom 124,200 (92%) have MDR-TB. Among MDR-TB patients, 31,547 (25.4%) are pre-XDR and and 1,615 (1.3%) are XDR-TB patients, according to the survey. Only 39,009 or 28% of drug-resistant TB cases were diagnosed and only 35,950 or 26% were treated in India in 2017, leaving a large diagnosis and treatment gap.
