Comparison of Clinical, Demographic Features, and Costs in Respiratory Syncytial Virus, Rhinovirus, and Viral Co-infections in Children Hospitalized with Viral Infections of the Lower Respiratory Tract.

Viruses are the most common cause of lower respiratory tract infections (LRTIs) in children. Our study aimed to shed light on co-infection by comparing it with the most common single agents, such as respiratory syncytial virus (RSV) and rhinovirus (RV), in terms of epidemiological, clinical, laboratory findings, and cost. This retrospective study analyzed medical records pertaining to infants aged below 5 years, hospitalized with a diagnosis of LRTI with RSV, RV, or co-infection.
