University of California, Irvine at IDWeek 2026

Oct 21–24, 2026 Washington, DC ~12k attendees Website

University of California, Irvine brings 17 presentations to IDWeek 2026 in Washington. Its program centres on antimicrobial resistance and infection prevention, from drug-resistant Gram-negative bacteria to multidrug-resistant organisms in nursing homes. Distinctive work uses large language models to judge whether hospital-onset bloodstream infections could have been prevented and asks how sharing a nursing home room affects resistant organism carriage.
