In 2007, the country with the highest estimated incidence rate of TB was Eswatini, with 1,200 cases per 100,000 people. In 2017, the country with the highest estimated incidence rate as a % of the population was Lesotho, with 665 cases per 100,000 people. [190] In South Africa, 54,200 people died in 2022 from TB.

These people can in turn infect other people with MDR-TB. [5] [8] MDR-TB caused an estimated 600,000 new TB cases and 240,000 deaths in 2016 and MDR-TB accounts for 4.1% of all new TB cases and 19% of previously treated cases worldwide. [13] Globally, most MDR-TB cases occur in South America, Southern Africa, India, China, and the former Soviet ...
