"Russia has the largest population of injecting drug users (IDUs) in the world — an estimated 1·8 million people. More than a third have HIV; in some regions, the proportion is nearer to three-quarters. Astonishingly, an estimated 90% of Russian IDUs have hepatitis C, and most patients co-infected with HIV and tuberculosis in Russia are drug-dependent."
