Multidrug-resistant Tuberculosis

Multidrug-resistant tuberculosis (MDR-TB) is a form of tuberculosis caused by bacteria that have become resistant to the two most effective antibiotics used to treat the disease—isoniazid and rifampicin. This resistance makes it much harder to cure MDR-TB with standard treatments, often requiring longer, more complex, and more expensive drug regimens. MDR-TB spreads in the same way as regular TB through the air when an infected person coughs or sneezes. Proper treatment adherence and early diagnosis are essential to prevent the development and spread of resistant strains.
