Kansas City is facing an “unprecedented” tuberculosis (TB) outbreak, the largest documented in U.S. history, with 67 confirmed cases as of January 24, 2025. Wyandotte County has been hit hardest, reporting 60 cases, while Johnson County has seven. The outbreak, which began in 2024, is still ongoing, prompting concerns even though public health officials stress the general population remains at “very low risk.”

Kansas health officials, alongside the CDC, are working to track, treat, and prevent further spread. TB cases have significantly dropped statewide, from 109 active cases in 2024 to just one by early 2025. However, the outbreak continues to challenge local resources, especially in Wyandotte County, where active cases have decreased from 65 last summer to around 32.

TB primarily affects the lungs and spreads through airborne particles, making early detection and treatment critical. Those with active TB become non-contagious after 10 days of medication and three negative sputum tests. Prevention is essential, especially for those with latent TB, which can progress to the active form.

Health officials are stressing the importance of vigilance, noting that although the situation is serious, the ongoing efforts by local and federal agencies aim to contain the outbreak. Timely treatment and public awareness remain key to controlling the spread of this infectious disease.
