Most international recommendations for tuberculosis control have been developed for multidrug-resistant (MDR) tuberculosis prevalence of up to around 5%. Yet we now face prevalence up to ten times higher in some places, where almost half of the patients with infectious disease are transmitting MDR strains of Mycobacterium tuberculosis. MDR tuberculosis is not an issue isolated in one city or country, but reflects a wider public health threat resulting from severely resistant forms of M tuberculosis. To adequately address MDR tuberculosis, more solid epidemiological information is needed to increase overall understanding of disease development and transmission.
