The objective of this study was to analyze the frequency and rates of community respiratory virus infections detected in NIH Clinical Center (NIHCC) patients from January 2015 through March 2021, comparing the trends before and during the COVID-19 pandemic.We conducted a retrospective study comparing frequency and rates of community respiratory viruses detected in NIHCC patients from January 2015 through March 2021. Test results from nasopharyngeal swabs/washes, bronchoalveolar lavages, and bronchial washes were included in this study. Results from viral challenge studies and repeat positives were excluded. A quantitative data analysis was completed using cross tabulations; comparisons were done using mixed models, applying Dunnett's correction for multiplicity.Frequency of all respiratory pathogens declined from an annual range of 0.88-1.97% from January 2015 through March 2020 to 0.29% between April 2020 and March 2021. Individual viral pathogens declined sharply in frequency during the same timeframe, with zero cases of influenza A/B or parainfluenza and one case of RSV. Rhino/enterovirus detection continued, but with a substantially lower frequency of 4.27% between April 2020 and March 2021, compared with an annual range of 8.65-18.28% from January 215 through March 2020.The decrease in viral respiratory infections detected in NIHCC patients during the pandemic was likely due to the layered COVID-19 prevention and mitigation measures implemented in the community and the hospital. Hospitals should consider continued use of nonpharmaceutical interventions in the future to prevent nosocomial transmission of respiratory viruses during times of high community viral load. |
