Here, we quantify the effects of the pandemic and related nonpharmaceutical interventions on the prevalence and seasonality of common pediatric respiratory illnesses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We performed a retrospective chart review within a large health network to identify incidence rates of common respiratory viruses and compared them to historical trends.

This trend continued until the Spring of 2021, at which time non-COVID infections resurged to rates higher than pre-COVID levels. In addition, the historically observed seasonality of these viruses was significantly disrupted by the pandemic. In particular, the historical peaks for influenza A and human metapneumovirus shifted from February and March, respectively, to bimodal peaks in December 2021 and May 2022; respiratory syncytial virus demonstrated an unprecedented Spring\/Summer season in 2021; parainfluenza type 1 was unusually active in 2022, an even-numbered year; and influenza B virtually disappeared during and immediately after the pandemic.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Our observations add to the growing body of literature supporting the hypothesis that human interactions are one of the key drivers of pediatric respiratory viral seasonality in addition to climate. Understanding the effect of human interactions on disease spread is crucial for the development of effective mitigation measures for future pandemics while avoiding dangerous spikes of other illnesses once those interventions are lifted.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1097\/pec.0000000000003340","type":"journal-article","created":{"date-parts":[[2025,2,4]],"date-time":"2025-02-04T05:00:41Z","timestamp":1738645241000},"page":"415-422","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Changes in Seasonal Patterns for Common Pediatric Respiratory Viruses During the COVID Pandemic"],"prefix":"10.1097","volume":"41","author":[{"given":"Tara","family":"Lozy","sequence":"first","affiliation":[{"name":"Center for Discovery and Innovation, Hackensack Meridian Health, Nutley, NJ"},{"name":"Division of Children\u2019s Research, Hackensack Meridian Health\u2014Joseph M Sanzari Children\u2019s Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rimma","family":"Perotte","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Hackensack Meridian Health\u2014Hackensack University Medical Center, Hackensack, NJ"},{"name":"Department of Biomedical Informatics, Columbia University, New York, NY"},{"name":"Department of Emergency Medicine, Hackensack Meridian School of Medicine, Nutley, NJ"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Austin","family":"Eigen","sequence":"additional","affiliation":[{"name":"Math Research Program, Paul D.
