Epidemiology of Community-Associated<i>Clostridium difficile</i>Infection, 2009 Through 2011

Abstract

Most patients with community-associated CDI had recent outpatient health care exposure, and up to 36% would not be prevented by reduction of antibiotic use only. Our data support evaluation of additional strategies, including further examination of C difficile transmission in outpatient and household settings and reduction of proton pump inhibitor use.
