Antiviral treatment for patients hospitalized with severe influenza infection may affect clinical outcomes.

cause it potentially affects the duration of patient isolation. The duration of colonization may impact patient-to-patient transmission during the index hospitalization in which patients with ESBL-producing E. coli and K. pneumoniae colonization were identified, as well as patient-to-patient transmission during future hospitalizations [6]. The significant association between outpatient antibiotic exposure and prolonged duration of stool colonization suggests the need for ongoing antimicrobial stewardship to help in limiting the emergence of hospitaland community-associated infections due to ESBLproducing microorganisms.
