A wave of tuberculosis cases hitting the Kansas City, Kansas, metro area has become the largest documented TB outbreak in the United States since monitoring began in the 1950s, according to the state health department.

Dozens of active and latent TB cases have been linked to the outbreak dating back to last year, local health officials say.

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.
