According to the WHO Global Tuberculosis (TB) Report 2024, Tanzania has improved on the two TB burden indicators (TB incidence rate and TB deaths). The TB incidence rate has been reduced by 40% from 306 in 2015 to 183 in 2023, and the number of deaths due to TB for both HIV-positive and negative has been reduced by 68% from 58,000 in 2015 to 18,400 deaths in 2023. This has put Tanzania among the 3 countries with high TB burdens on track to reach the END TB milestone 2025 of reducing the Incidence rate by 50% in 2025 and among 13 countries in reducing the number of TB deaths by 75%. TB treatment success rates have reached 96% for TB cases notified in 2023 above the national and WHO targets of >90%.
