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

Health officials in Johnson County provided an update Wednesday on tuberculosis cases connected to an ongoing outbreak that started in March 2024.

An ongoing tuberculosis outbreak in two Kansas counties has sickened dozens since January 2024. Health officials are raising the alarm over a large and ongoing tuberculosis (TB) outbreak in Kansas.

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

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.

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

You don’t need to have the vaccine to attend colleges in Kansas, but some do require you to get tested for tuberculosis before enrolling and going to classes on campus, like at the University of Kansas.

“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.”

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

Kansas is experiencing record-high tuberculosis cases in two counties. The Kansas Department of Health and Environment and a TB expert weigh in on the public risk.

The Kansas City metro area is experiencing the largest outbreak in U.S. history, with low risk to the general public, Kansas health officials say.
