In this context, we conducted a study with the objective of identifying the clinical characteristics and outcomes of rhinovirus infection in comparison with other respiratory viruses in children hospitalized in one of the largest pediatric hospitals in the capital of Romania. Methods: We conducted a retrospective study among children hospitalized for influenza-like illness symptoms and who were tested by multiplex RT-PCR with a nasopharyngeal swab between May 2020 and December 2021. Results: A total of 496 children were eligible for inclusion in the study, and the positivity rate for at least one virus was 58.5%. The rhinovirus was identified in 138 patients (median age 12.5 months), representing 27.8% of all children tested and 49.3% of all positive samples. Although the clinical features of children with rhinovirus were dominated by cough (63.7%) and dyspnea (51.6%), no symptoms were identified that were strongly associated with rhinovirus infection in comparison to other respiratory viruses. The probability of receiving an antibiotic prescription was 1.92 times lower (p = 0.011) in children who tested positive for rhinovirus compared to children with negative RT-PCR results. The incidence of acute bronchiolitis or acute bronchitis, acute respiratory failure, and acute otitis media was higher among rhinovirus-positive children than among those who tested negative via RT-PCR. However, the incidence of these conditions was similar among children who tested positive for other respiratory viruses. Conclusions: Rhinovirus was the most prevalent virus identified in children hospitalized with influenza-like illness symptoms. The utilization of multiplex RT-PCR molecular tests is instrumental in elucidating etiology with precision and implementation of these advanced diagnostic methods, which can bring significant benefits in practice. A positive result for rhinovirus helps to reduce the unnecessary administration of antibiotics and optimizes patient management, thus decreasing the risk of severe complications such as acute respiratory failure and acute otitis media.<\/jats:p>","DOI":"10.3390\/children11111303","type":"journal-article","created":{"date-parts":[[2024,10,28]],"date-time":"2024-10-28T07:04:04Z","timestamp":1730099044000},"page":"1303","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Exploring the Clinical Characteristics and Outcomes of Rhinovirus Infection in Hospitalized Children Compared with Other Respiratory Viruses"],"prefix":"10.3390","volume":"11","author":[{"given":"Sigrid","family":"Covaci","sequence":"first","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudiu","family":"Filimon","sequence":"additional","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mihai","family":"Craiu","sequence":"additional","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 050474 Bucharest, Romania"},{"name":"National Institute for Mother and Child Health, Alessandrescu-Rusescu, 020395 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1753466621995050","DOI":"10.1177\/1753466621995050","article-title":"Respiratory viral infections in the elderly","volume":"15","author":"Watson","year":"2021","journal-title":"Ther.
