The three previous reports were published in 1997, 2000 and 2004, and included data from 35, 58 and 77 countries, respectively.

This report includes drug susceptibility test (DST) results from 91 577 patients from 93 settings in 81 countries and 2 special administrative regions (SARs) of China (i.e. Hong Kong and Macau). The data were collected between 2002 and 2007, and represent more than 35% of the global total of notified new smear-positive tuberculosis (TB) cases.
