Schematic map of the intensive care unit (ICU) and the distribution of the outbreak multidrug-resistant Acinetobacter baumannii (MDR-Ab) strain and the other MDR-Ab strains identified in the outbreak. Numbers 1–10 indicate the bed number (rectangles) in the ICU. The black dots represent the outbreak strain; the white letters inside them are the patient numbers. The gray shapes represent the isolates from the environment identified as outbreak strain (●, isolates from bedrails; ■, isolates from bed sheets; ♦ isolates from invigilator or blood filtering machine keyboards; ★, isolates from nurses’ notebook, desk, and calculator; ▼, isolates from dispensing table, scrub sink, and the medical treatment room). The ellipsis indicates the scrub sink. The dashed lines indicate physical barriers (drapes). There was a two-meter distance between adjacent beds.
