Epidemiology of antituberculosis drug resistance 2002-07: an updated analysis of the Global Project on Anti-Tuberculosis Drug Resistance Surveillance.

The article presents an analysis of the Global Project on Anti-Tuberculosis Drug Resistance Surveillance. Drug susceptibility data from 90726 patients in 83 countries and territories were gathered from 2002 to 2007. Researchers found that multidrug-resistant tuberculosis remains a threat to tuberculosis control in provinces in China and countries of the former Soviet Union. They believe that the lack of data on drug resistance in many countries, especially in Africa, emphasises the need to develop easier methods for surveillance.
