Seasonal Trends and Interactions of Viral Pathogens in Children Presenting with Acute Respiratory Tract Infections in the Advancing Periods of SARS-CoV-2 Pandemic

Although various bacteria and viruses have been identified in the etiology of acute respiratory tract infections (ARI), 90% of acute ARIs that develop in children are of viral origin. The aim of this study was to investigate the seasonal trends and interactions between infectious agents and to determine the risk factors associated with ARI in children aged 1-15 years admitted to the Pediatric Emergency Department of Manisa Celal Bayar University Hospital in the advancing periods of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic. To determine the bacterial and viral agents, samples were taken from 314 patients attending to the hospital with symptoms suggestive for ARI, between 06/01/2021 and 05/31/2022. Viral and bacterial agents were identified by multiplex polymerase chain reaction (PCR) and automated identification system, respectively. Demographic data of the participants and possible risk factors for ARI were recorded in the questionnaires. In the study, viral agents were detected in 77.3% of the children, and the most common infectious agent was rhinovirus/enterovirus (RV/EV) (36.3%), followed by influenza viruses (11.2%), and SARS-CoV-2 (10.5%). While RV/EV positivity was found to be higher in children with moderate and below average (p< 0.001) hand hygiene, influenza positivity was found higher in those attending school/preschool institution (p< 0.001) and whose mothers working full-time (p< 0.001). Respiratory syncytial virus positivity was associated with maternal smoking (p= 0.013) and home overcrowding (p= 0.014). Bacterial colonization was detected in 33 (11.6%) of 284 children whose swabs were taken for both bacterial and viral agents and the most frequently detected agents were Staphylococcus aureus (60.6%) and Pseudomonas aeruginosa (15.2%). Having siblings (p= 0.008) and maternal smoking (p= 0.012) were found to be associated with the detection of bacterial agents. In this study, in the advanced period of the pandemic, the most detected agents and seasonal characteristics were found to be similar to the pre-pandemic period. It is thought that knowing the regional etiology and risk factors will contribute to taking the necessary local control and protective measures.
