Infrequent Air Contamination With Acinetobacter baumannii of Air Surrounding Known Colonized or Infected Patients

Using a validated air sampling method we found Acinetobacter baumannii in the air surrounding only 1 of 12 patients known to be colonized or infected with A. baumannii. Patients' closed-circuit ventilator status, frequent air exchanges in patient rooms, and short sampling time may have contributed to this low burden.
