◆ The World Health Organization (WHO) publishes three high burden country lists TB, TB/HIV, multidrug resistant TB (MDRTB). Each list contains 30 countries: 20 countries with the highest number of cases in absolute terms, and 10 countries, not among the first 20, with the largest per capita case rate that meet a minimum threshold in terms of absolute numbers of cases.

Central African Republic, Congo, Lesotho, Liberia, Namibia, UR Tanzania and Zambia are high TB and TB/HIV burden countries.
