WASHINGTON, DC—Mario Raviglione has been the director of the World Health Organization’s Stop TB Department since 2003. He spoke with John Donnelly about his frustrations with detecting cases of multidrug-resistant TB as well as the slowness in the use of the GeneXpert machine, which can detect drug-resistant TB in two hours, compared to two months from older tests.
Q: With the International AIDS conference approaching, what should people know about TB and HIV-TB co-infection?
A: There has been much progress in addressing HIV-TB co-infection. Still, though, we are not there yet. Some countries are offering TB services to up to 90 percent of people who are co-infected with HIV. But other countries are reaching well under 50 percent.
