Study Identifies Risk Factors for Severe Disease in Hospitalized Children with RTIs
A study conducted at two Canadian pediatric centers has found that more than one in five children hospitalized with acute respiratory tract infections (RTIs) develop severe disease. The research, published in JAMA Network Open, involved 2,585 children hospitalized between July 2022 and June 2023. It identified that children transferred from a referring hospital, those with chronic conditions, and those with specific viral infections are at higher risk for severe outcomes. The study highlighted that influenza is more often associated with acute respiratory distress syndrome (ARDS) and septic shock, while human metapneumovirus is linked to cardiac complications. Despite low mortality rates, the burden of severe illness remains high, emphasizing the need for targeted prevention and ongoing surveillance.
