Abstract

We measured droplet aerosol dissemination of carbapenem-resistant Acinetobacter baumannii (CRAB) by sampling air surrounding 10 ventilated patients with CRAB isolated in sputum. Over 70 hours, we sampled 252,000 L of air; CRAB was detected in 39,600 L (16%). CRAB growth was higher during patient care, notably suctioning and sheet changing.
