Carbapenem-Resistant Enterobacteriaceae Rectal Screening during an Outbreak of New Delhi Metallo-β-Lactamase-Producing Klebsiella pneumoniae at an Acute Care Hospital

The manual method for CRE screening was useful for detecting patients with asymptomatic CRE carriage but was time-consuming and costly.
