In 2011, 1.4 million died from it, making it the world’s deadliest infectious disease after AIDS. Thanks to billions of dollars spent on diagnosis and treatment over the past decade, deaths and infections are slowly declining. Yet a disturbing phenomenon has emerged that could not only reverse any gains we’ve made, but also encourage the spread of a newly resistant form of the disease.

In the largest study of its kind, to be published today in the International Journal of Tuberculosis and Lung Disease, colleagues and I have found that fake and poorly made antibiotics are being widely used to treat tuberculosis. These substandard drugs are almost certainly making the disease more resistant to drugs, posing a grave health threat to communities around the world.
