FIG 2.

Patient movements and positive environmental samples with a single strain of K. quasipneumoniae (KpIIA) in the STBICU. Colored bars for patients match rooms where environmental isolates were identified. Black bars represent rooms with no KpIIA identified. The dotted lines indicate STBICU closure with removal and new installation of sink drains and exposed sink plumbing. Patient 1 is not depicted, as there was no admission to the STBICU and no overlap in time or space with other patients carrying KpIIA.
