A Silver Lining? Fewer Non-Severe Acute Respiratory Syndrome Coronavirus 2 Respiratory Viruses During the Coronavirus Disease 2019 Pandemic

J Infect Dis. 2021 Nov 22;224(10):1751-1755. doi: 10.1093/infdis/jiab191.

Abstract

Nonpharmaceutical interventions (NPIs) have "flattened the curve" of the coronavirus disease 2019 pandemic; however the effect of these interventions on other respiratory viruses is unknown. We used aggregate level case count data for 8 respiratory viruses and compared the institutional and statewide case counts before and during the period that NPIs were active. We observed a 61% decrease (incidence rate ratio, 0.39; 95% confidence interval, .37-.41; P < .001) in non-severe acute respiratory syndrome coronavirus 2 respiratory viral infections when NPIs were implemented. This finding, if further verified, should guide future public health initiatives to mitigate viral epidemics.

Keywords: COVID-19; nonpharmaceutical interventions; respiratory virus; seasonal respiratory viruses.
