Comparative Analysis of Symptomatology in Hospitalized Children with RSV, COVID-19, and Influenza Infections
MEDICAL SCIENCE MONITOR(2023)
Abstract
Background: The clinical course of respiratory syncytial virus (RSV), SARS-CoV-2, and influenza infections comprises many non-specific symptoms, which makes diagnosis difficult. The aim of this study was to retrospectively analyze the symptomatology of these infections in children and to search for correlations between them. Material/Methods: A total of 121 children with a positive RSV (n=61), influenza (n=31), or SARS-CoV-2 (n=29) antigen test were enrolled in this retrospective analysis. Children were aged up to 71 months (median, 8 months). The collected data were collated by performing statistical analysis using the chi-square test and comparing the results using OR (odds ratio) and 95%CI (confidence interval). Results: There was a higher risk of fever in children with influenza than in those with RSV. Patients infected with RSV had a higher risk of nasal blockage than those with SARS-CoV-2. Dyspnea was more common in RSV infection than in influenza. Severe, sleep-awakening cough was more frequent in children with RSV than in those with COVID-19. Influenza was more prevalent in children aged >24 months than in those aged 7-24 months. RSV-infected children had a higher risk of numerous auscultatory changes compared to those with SARS-CoV-2. In the case of RSV infection, symptoms requiring hospitalization occurred later than in SARS-CoV-2 infection. Conclusions: Children aged >24 months were at higher risk of contracting influenza. Numerous auscultatory changes, nasal blockage, and dyspnea were more common in children with RSV. There was a higher risk of dyspnea in children with RSV. Fever was more frequent in children with influenza. However, none of the symptoms clearly indicated the etiology of the infection.
