Situation in 2014
Drug-resistant TB poses a major threat to control of TB worldwide. In 2014, there were an estimated 480 000 (range: 360 000–600 000) new cases of MDR-TB worldwide, and approximately 190 000 (range: 120 000–260 000) deaths from MDR-TB.
More TB patients were tested for drug resistance in 2014 than ever before. Worldwide, 58% of previously treated patients and 12% of new cases were tested. This improvement is partly due to the adoption of rapid molecular tests.
123 000 cases of rifampicin-resistant or multidrug-resistant TB (MDR-TB) were detected worldwide. This represented just 41% of the 300 000 notified pulmonary TB cases estimated to have MDR-TB.
A total of 111 000 people started MDR-TB treatment in 2014.
