Pathogen Profile of Children Hospitalised with Viral Respiratory Infections in Galati County, Romania

Respiratory infections are the most common infectious diseases among children, representing a cause of death and generating a significant number of hospitalisations. The aim of the study was to analyse the epidemiological and clinical characteristics of viral pathogens causing respiratory tract infections in newborns and young children admitted to Galati pediatric hospital between October 2022 and December 2023. The diagnosis was performed using multiplex RT-PCR panels, which allowed simultaneous identification of respiratory pathogens (viruses and bacteria). From a total of 803 hospitalised patients with respiratory diseases, 607 (75.6%) children had a positive result for at least one respiratory virus and 96 patients (11.9%) were identified with bacterial infections. Mixed coinfections were found in almost half of the patients (44.5%). Most of RSV positive children had an increased length of stay, more than 7 days. It was shown a decline in severe cases of viral respiratory infections with prolonged hospitalisation as patients age up to 5 years.
