The World Health Organization warns of a sharp increase in the level of drug resistance in tuberculosis in the world. Leading position in the number of cases of drug-resistant TB or the former Soviet Union is occupied. WHO report "Resistance to anti-TB drugs in the world," based on data collected from 90 thousand patients in 81 countries between 2002 and 2006. According to experts, the proportion of cases of MDR-TB in about 5% of the total number of patients (approximately 500,000 of the 9 million annually to the patient). Particularly high prevalence of drug-resistant tuberculosis in the former Soviet Union. For example, in the Azerbaijani capital Baku pathogens were infected with multi-drug resistance to 22.3% of total patients. In Moldova, the comparable figure was 19.4%, in Donetsk - 16%, in the Tomsk region, Russia 15%, in Tashkent - 14.8%. Chinese statistics also shows the increasing prevalence of drug-resistant TB in the country. According to recent data, in north-eastern China resistant forms of up to 7.5% of the total number of infections. The prevalence of drug resistant tuberculosis in Africa is still unknown: most African countries are not able to provide the relevant statistics for lack of laboratories able to conduct appropriate tests adequately. According to the head of the WHO program antituberculous Mario Raviglione, the rate of drug resistant tuberculosis in the world has surpassed the most pessimistic forecasts. 10 years ago, many scientists have the data to 10% of resistant cases found in some areas in question, while others expressed the belief that higher prices are simply impossible, said Raviglione. "We now know that this is possible, and it shows that we are wrong, TB, where spread these forms continue to fight" - he stressed.
