The data based on ICD-10 codes of lower respiratory tract infections and microbiological analysis of respiratory and gastrointestinal infections were collected. The retrospective five-year analysis of the medical records revealed a substantial decrease in respiratory tract infections during the pandemic year (from April 2020 to March 2021). We noted an 81% decline in the LRTI-associated hospital admissions based on the ICD-10 analysis (from a mean of 1170 admissions per year in the previous four years to 225 admissions between April 2020 through March 2021). According to microbiological analysis, there were 100%, 99%, 87%, and 47% drops in influenza virus, respiratory syncytial virus, rotavirus, and norovirus cases reported respectively during the pandemic season until April 2021 in comparison to pre-pandemic years. However, the prevalence of gastrointestinal bacterial infections was stable. Moreover, in August 2021, an unexpected rise in RSV-positive cases was observed. The measures applied during the COVID-19 pandemic turned out to be effective but also had a substantial contribution to the so-far stable epidemiological situation of seasonal infections.<\/jats:p>","DOI":"10.3390\/microorganisms10010178","type":"journal-article","created":{"date-parts":[[2022,1,16]],"date-time":"2022-01-16T20:45:21Z","timestamp":1642365921000},"page":"178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["The Impact of the COVID-19 Pandemic Lockdown on Pediatric Infections\u2014A Single-Center Retrospective Study"],"prefix":"10.3390","volume":"10","author":[{"given":"Magdalena","family":"Grochowska","sequence":"first","affiliation":[{"name":"Department of Pediatric Pneumonology and Allergy, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3706-0210","authenticated-orcid":false,"given":"Dominika","family":"Ambro\u017cej","sequence":"additional","affiliation":[{"name":"Department of Pediatric Pneumonology and Allergy, Medical University of Warsaw, 02-091 Warsaw, Poland"},{"name":"Doctoral School, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aneta","family":"Wachnik","sequence":"additional","affiliation":[{"name":"Department of Laboratory Diagnostics and Clinical Immunology of the Developmental Age, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Urszula","family":"Demkow","sequence":"additional","affiliation":[{"name":"Department of Laboratory Diagnostics and Clinical Immunology of the Developmental Age, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edyta","family":"Podsiad\u0142y","sequence":"additional","affiliation":[{"name":"Department of Laboratory Diagnostics and Clinical Immunology of the Developmental Age, Medical University of Warsaw, 02-091 Warsaw, Poland"},{"name":"Centre for Preclinical Research, Department of Pharmaceutical Microbiology, Faculty of Pharmacy, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6613-2012","authenticated-orcid":false,"given":"Wojciech","family":"Feleszko","sequence":"additional","affiliation":[{"name":"Department of Pediatric Pneumonology and Allergy, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2137","DOI":"10.1001\/jama.2020.5460","article-title":"Governmental public health powers during the COVID-19 pandemic","volume":"323","author":"Gostin","year":"2020","journal-title":"JAMA"},{"key":"ref_2","unstructured":"(2022, January 04).
