GlobalPost’s “Global Pulse” blog interviews Mario Raviglione, the director of the WHO’s Stop TB Department since 2003, “about the progress and frustrations with detection and treatment of tuberculosis [TB].” Among other topics, Raviglione discusses “progress in addressing HIV-TB co-infection,” the emergence of extensively drug-resistant TB (XDR-TB), and research in diagnostics, such as the GeneXpert machine, which gives a “very quick” diagnosis of MDR-TB, according to the blog (Donnelly, 7/12).
