Starting in 2024, the U.S. state of Kansas experienced a sudden rise in cases of tuberculosis, with 68 active cases. 113 cases of tuberculosis were recorded in Kansas in 2024, compared to 51 in 2023. It is one of the largest tuberculosis outbreaks reported in the U.S. since surveillance for large outbreaks began in 2008. The Kansas Department of Health and Environment has not publicly identified the source of the outbreak. On November 14, 2025, after all patients had completed treatment, the Kansas Department of Health and Environment declared the end of the outbreak.
