*ESBL-E, extended-spectrum β-lactamase–producing Enterobacteriaceae; SE, standard error; pdt, person-days of travel.
†The ESBL incidence rate/100 pdt is represented by 4 travelers returning from North Africa who carried ESBL-E: 3 of them had traveled for 7 days and 1 had a 25-day stay abroad, which accounts for the high SE.
