Context to Research
◆ 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.
◆ African countries appearing in all three lists are Angola, DR Congo, Ethiopia, Kenya, Mozambique, Nigeria, South Africa and Zimbabwe. Central African Republic, Congo, Lesotho, Liberia, Namibia, UR Tanzania and Zambia are high TB and TB/HIV burden countries. Botswana, Cameroon, Chad, Ghana, Guinea-Bissau, Malawi, Eswatini and Uganda are only high TB/HIV burden countries. Sierra Leone is only a high TB burden country and Somalia only a high MDR-TB country.
