Anti-tuberculosis drug resistance in the world

This report presents survey and surveillance data collected between 2002 and 2006 on drug resistance in tuberculosis (TB). It includes drug susceptibility test results from over 91,000 patients from 81 countries. New data are available from several high TB burden countries including: India, China, Russian Federation, Indonesia, Ethiopia, Vietnam, and Tanzania. The data records the highest ever prevalence of multi-drug resistant tuberculosis (MDR-TB). There are nearly half a million new cases of MDR-TB a year, with the highest rate recorded in Baku in Azerbaijan. Further, extensively drug-resistant tuberculosis (XDR-TB), a virtually untreatable form of TB, has been recorded in 45 countries.
The report argues that countries and the international community need to address TB drug resistance aggressively. In addition to specifically confronting drug-resistant TB and saving lives, programmes worldwide must immediately improve their performance in diagnosing all TB cases rapidly and treating them until cured as this is the best way to prevent the development of drug resistance. Approximately US$ 4.8 billion is needed for overall TB control in low- and middle-income countries in 2008, with US$ 1 billion for MDR-TB and XDR-TB.
