World TB Day

World TB Day, held on March 24 each year, is an occasion for people around the world to raise awareness about the devastating health and economic consequences of tuberculosis (TB) and to advocate for TB prevention and control activities.

In 2024, 24 Minnesota counties reported a total of 194 new cases of active TB disease, compared to 160 in 2023. The case count in 2024 was the highest since 2008. Worldwide, an estimated 10.8 million people became sick with TB disease in 2023. TB is again the leading cause of death worldwide from infectious diseases, replacing COVID-19. TB can be cured with proper medical care, yet it still kills over 1.25 million people every year, including around 600 in the United States. Drug resistance to TB medications continues to be a concern.

The number of active TB cases is only the tip of the iceberg. For every person with active TB, many more have latent TB infection (LTBI). The World Health Organization estimates that close to a quarter of the world’s population is infected with TB. Overall, 5-10% of them will develop active TB unless they receive treatment for LTBI. In addition to treating people with active TB, we must promote screening and treatment of persons at greatest risk of developing active disease.
