State health officials said that dozens of people in the Kansas City, Kan., area have the disease, which has drawn a federal response.

A tuberculosis outbreak in Kansas has killed two people and caused at least 146 to become infected with the potentially deadly respiratory disease during one of the largest outbreaks in the nation's history.

Kansas health officials are tackling the largest tuberculosis outbreak in US history, with 67 confirmed cases since the start of 2025.

More than 60 people were being treated in the Kansas City area as of Friday, according to the state health department.

“While TB cases in Wyandotte and Johnson counties are getting attention, we want to assure our residents that what we’re seeing in Saline County is normal,” said Jason Tiller, Saline County Health Officer. “There is no immediate reason for concern. TB is preventable, treatable, and does not pose a general risk to the public.”

The Kansas Department of Health and Environment has said the risk to the general public in surrounding counties remains “very low.”

The Johnson County Department of Health and Environment (JCDHE) says all TB patients in the county have completed treatment and are not infectious

The state has seen tuberculosis cases double between 2023 and 2024, with the CDC offering support on the ground.

The outbreak started last January. Kansas health officials say numbers are trending downward, but they still expect to find more cases.

An ongoing tuberculosis outbreak in Kansas has become the largest in U.S. history. The Kansas Department of Health and Environment has been tracking this outbreak for over a year.
