Acquisition and long-term carriage of multidrug-resistant organisms in us international travelers

Abstract

We performed prospective screening of stool for multidrugresistant organisms from 608 US international travelers and identified an acquisition rate of 38% following travel. Carriage rates remained significantly elevated for at least 6 months posttravel. Travel-related diarrhea was a risk factor for acquisition, as well as for long-term carriage upon return.
