Impact of SARS-CoV-2 Prevention Measures on Non-SARS-CoV-2 Hospital-Onset Respiratory Viral Infections: An Incidence Trend Analysis from 2015-2023.

We reviewed hospital-onset respiratory viral infections, 2015-2023, in one hospital to determine whether SARS-CoV-2 transmission prevention measures prevented non-SARS-CoV-2 respiratory viral infections. Masking, employee symptom attestations, and screening patients and visitors for symptoms were associated with a 44-53% reduction in hospital-onset influenza and RSV, accounting for changes in community incidence.
