Poorly manufactured and fraudulent medicines kill thousands of people around the world each year. For infectious diseases like malaria and HIV, shoddy medicines also accelerate drug resistance and dramatically alter the course of epidemics. With few new drugs under development, recent progress against these major killers in the poorest countries is precarious.
Bad drugs have become a big problem for one major infectious disease in particular: tuberculosis. If we don’t solve this issue, we may see the gains we’ve made against TB slip away.
