Impatto delle codetectazioni di virus respiratori sulla gravità della malattia da virus respiratorio sinciziale nei bambini piccoli in cura primaria.

BACKGROUND: Young children with respiratory syncytial virus (RSV) often have viral coinfections. This study assessed the impact of respiratory viral codetections on RSV disease burden in children < 5 years and whether this varies by specific codetected viruses. METHODS: Retrospective analyses were performed using data from the RSV ComNet study prior to implementation of passive immunisation. Children < 5 years with acute respiratory infection (ARI) were eligible for testing for RSV and other viruses (multiplex real-time Polymerase Chain Reaction). Primary care physicians completed a short report on day 1, and parents completed follow-up questionnaires (digital or by phone) on days 14 and 30
