Globally, 5% of new bacteriologically confirmed TB
cases and 9% of those previously treated were tested
for MDR-TB in 2012. The proportions have increased
slightly in recent years but remain below the target set
for 2012 by the Global Plan. Among TB cases which
were notified and confirmed as MDR-TB in 2012, 23%
were reported to have had DST carried out for both
fluoroquinolones and second-line injectable drugs,
to test for XDR-TB.
