— indicates values that cannot be calculated.
a
Estimates for all years are recalculated as new information becomes available and techniques are refi ned, so they may differ from those published previously.
b
Best, low and high indicate best estimates followed by lower and upper bounds. The lower and upper bounds are defi ned as the 2.5th and 97.5th centiles of outcome
distributions produced in simulations.
ress compared with 2010. In Brazil and Uganda, low rates
reflect a relatively high proportion of patients for whom
the outcome of treatment was not evaluated (10% and
13%, respectively) and high default rates (11% in both
countries). In the Russian Federation, treatment failure
rates are high, possibly linked to MDR-TB.
3.4.2 All new cases
Data on treatment outcomes for all new cases of TB are
shown in Table 3.6. Globally, the rate of treatment success
was 85% in 2010. Among WHO’s six regions, the highest
rates were in the Eastern Mediterranean (88%), South-
East Asia (89%) and Western Pacific (92%) regions. The
treatment success rate was 73% in the African Region,
74% in the Region of the Americas and 74% in the
European Region. The data for the African Region were
affected by missing data for South Africa. Once these are
available and reported, the treatment success rate will be
higher.
Of the 22 HBCs, 14 reached or exceeded a treatment
success rate of 85% among all new cases in 2010. The
eight countries that reported lower rates of treatment success
were Brazil (72%), Ethiopia (77%), Nigeria (81%),
the Russian Federation (66%), South Africa (53%), 1
Thailand (83%), Uganda (68%) and Zimbabwe (76%).

The NTP in South Africa noted that data reported to WHO
were incomplete; the figure of 53% is thus an underestimate.
