Methods: This retrospective study included 52 children with COVID-19 and 43 children with RSV infection younger than 36 months hospitalized in a pediatric department between September 2021 and March 2022. Clinical and laboratory findings, methods of treatment and hospitalization length were compared. Results: In the RSV group, significantly higher rates of cough (93.2% vs. 38.5%), rhinitis (83.7% vs. 50%), dyspnea (83.7% vs. 21.1%), crackles (69.8% vs. 5.8%) and wheezes (72.1% vs. 9.6%) were observed. The COVID-19 group had significantly higher rates of fever (80.8% vs. 37.2%) and seizures (13.5% vs. 0%). Patients with RSV infection had significantly higher rates of bronchodilator therapy (88.37% vs. 5.77%) and oxygen therapy (48.8% vs. 7.7%) and required a longer hospital stay (8 vs. 3 days). In admission, the majority of the patients from both groups were not treated with antibiotics, but because of clinical deterioration and suspected bacterial co-infections, antibiotics were administered significantly more frequently in the RSV group (30.2% vs. 9.6%). Conclusions: RSV infection in infants and small children had a more severe course than COVID-19 infection. RSV infection was associated with a longer hospitalization period and required more elaborate treatment.<\/jats:p>","DOI":"10.3390\/jcm11237088","type":"journal-article","created":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T07:10:27Z","timestamp":1669792227000},"page":"7088","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Comparison of COVID-19 and RSV Infection Courses in Infants and Children under 36 Months Hospitalized in Paediatric Department in Fall and Winter Season 2021\/2022"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3605-5663","authenticated-orcid":false,"given":"Anna","family":"Fedorczak","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Nephrology and Immunology, Medical University of Lodz, 90-419 Lodz, Poland"},{"name":"Department of Endocrinology and Metabolic Diseases, Polish Mother\u2019s Memorial Hospital Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia","family":"Zieli\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Nephrology and Immunology, Medical University of Lodz, 90-419 Lodz, Poland"},{"name":"Department of Pediatrics, Immunology and Nephrology, Polish Mother\u2019s Memorial Hospital Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"Nosek-Wasilewska","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Immunology and Nephrology, Polish Mother\u2019s Memorial Hospital Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Miko\u0142ajczyk","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Immunology and Nephrology, Polish Mother\u2019s Memorial Hospital Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Lisiak","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Immunology and Nephrology, Polish Mother\u2019s Memorial Hospital Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krzysztof","family":"Zeman","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Nephrology and Immunology, Medical University of Lodz, 90-419 Lodz, Poland"},{"name":"Department of Pediatrics, Immunology and Nephrology, Polish Mother\u2019s Memorial Hospital Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcin","family":"Tkaczyk","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Nephrology and Immunology, Medical University of Lodz, 90-419 Lodz, Poland"},{"name":"Department of Pediatrics, Immunology and Nephrology, Polish Mother\u2019s Memorial Hospital Research Institute, 93-338 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,29]]},"reference":[{"key":"ref_1","unstructured":"(2022, October 06).
