A yearlong outbreak of tuberculosis in the Kansas City, Kansas area has taken local experts aback, even if it does not appear to be the largest outbreak of the disease in U.S. history as a state health official claimed last week.

According to data from the Kansas Department of Health and Environment (KDHE), the cases have all occurred in Wyandotte County and Johnson County, both part of the greater Kansas City metro area. So far, 67 "active" TB infections and 79 "latent," or "inactive" infections have been linked to the outbreak.

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.
