Multidrug-resistant tuberculosis (MDR-TB)

Situation in 2012

Among patients with pulmonary TB notified in 2012, i.e. the group of patients known to National TB Programmes and that can be tested for drug resistance using WHO-recommended diagnostic tests, there were an estimated 300 000 (range: 220 000–380 000) MDR-TB cases.

However, only 5% of new bacteriologically-confirmed TB cases and 9% of those previously treated for TB were tested for MDR-TB in 2012.

A total of 94 000 TB cases eligible for MDR-TB treatment (84 000 with MDR-TB and 10 000 with rifampicin resistance detected using Xpert MTB/RIF) were notified in 2012, and just over 77 000 people with MDR-TB were started on second-line treatment.

The 2015 treatment success target of ≥75% set in the Global Plan to Stop TB 2011–2015 for MDR-TB was reached by 34 of 107 countries that reported outcome data for the 2010 patient cohort. However, overall only 48% of patients were successfully treated.
