Tuberculosis (TB) remains one of the deadliest infectious diseases worldwide, as the current WHO Global Tuberculosis Report 2025 shows. Last year, the disease claimed over 1.2 million lives and affected an estimated 10.7 million people. Despite measurable advances in diagnosis, treatment and innovation, ongoing challenges in funding and equitable care threaten hard-won progress in the global fight against TB.
Between 2023 and 2024, the global rate of TB disease fell by almost 2%, while deaths fell by 3%. These declines signal continued recovery of essential health services following the disruptions caused by the COVID-19 pandemic. Some regions and countries are showing continued progress, proving that strong policy commitments and investments can combat this ancient disease.
The WHO Africa region achieved a 28% reduction in TB incidence rates and a 46% reduction in deaths between 2015 and 2024. The European region saw even larger declines, with incidence falling by 39% and deaths falling by 49%. Over 100 countries achieved at least a 20% reduction in TB incidence rates during this period, and 65 countries recorded reductions of 35% or more in TB-related deaths.
The advances in TB diagnosis and treatment are remarkable. In 2024, 8.3 million people were newly diagnosed and accessed treatment, representing about 78% of those diagnosed in the same year. Coverage of rapid tests for TB diagnosis increased from 48% in 2023 to 54% in 2024. Treatment of drug-sensitive TB remained highly effective with a success rate of 88%.
Nevertheless, global progress remains far behind the goals of the End TB Strategy. A major obstacle is global funding for TB, which has stagnated since 2020. In 2024, only $5.9 billion was available for prevention, diagnosis and treatment, just over a quarter of the annual target of $22 billion set for 2027. Cuts in international donor funding from 2025 pose a serious challenge.
WHO calls for sustained political commitment, increased domestic investment and intensive research to accelerate progress. Dr. Tereza Kasaeva, Director of the WHO Division of HIV, TB, Hepatitis and STIs, emphasizes that with political commitment, sustained investments and global solidarity, there is an opportunity to finally defeat this ancient killer.
