Overview
Introduction: Respiratory viruses contribute significantly to respiratory morbidity in children with a high burden on society.
Objectives: Retrospective analysis of the epidemiological characteristics of selected respiratory viruses detected in often ill pediatric patients.
Materials and methods: Assessment of laryngeal swab outcomes. The results were examined using RT-PCR method for a coherent group of 10 viruses: rhinovirus (RV), adenovirus (ADV), respiratory syncytial virus (RSV), human coronavirus (HCoV), parainfluenza virus (PIV 1-4), human bocavirus (HboV), and human metapneumovirus (HMPV). The data collection period was established from January 2022 to June 2023. This period corresponded to the investigation of 722 samples. The variables analysed included age, sex, month of detection of the pathogen, and diagnosis of acute respiratory infection. The average age of the children was 5.6 ± 4.3 years.
Results: Among all samples, more than half (373; 52%) were confirmed to contain a viral pathogen. The virus with the highest prevalence was RV (184; 49%). ADV was the second most prevalent (47; 12%), closely followed by respiratory RSV (40; 11%). An analysis of virus detection over different months revealed typical epidemiological patterns, with RV and ADV present throughout the year, and RSV, PIV 1-4, and HMPV showing seasonal patterns. The two most common viruses, RV and RSV, exhibited a differential age-related presence in children.
Conclusion: This study found that the prevalence of specific respiratory viruses varies according to the season and age of paediatric patients with acute respiratory infections. By identifying specific pathogens, we can enhance therapeutic management and prevent possible complications of viral respiratory infections.
