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.

A CDC spokesperson identified two outbreaks in the last decade linked to more tuberculosis cases than the ongoing outbreak centered in Wyandotte County.

Kansas is currently experiencing a large tuberculosis outbreak, but federal health officials are countering the claim it’s a U.S. record.
