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

Abstract

We reviewed hospital-onset respiratory viral infections, 2015–2023, in one hospital to determine whether Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) transmission prevention measures prevented non-SARSCoV-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 respiratory syncytial virus (RSV), accounting for changes in community incidence.
