Which Viruses Hit Kids Hardest?
Study compares pathogen type, comorbidities, and clinical severity in pediatric admissions
A multicenter cohort study published in JAMA Network Open examined pediatric patients hospitalized for viral respiratory infections, revealing severe illness was notably linked to respiratory syncytial virus (RSV), influenza, and preexisting chronic conditions. The study reviewed 516 children under 18 years admitted from September 2023 to December 2024 across 12 centers in Italy. It found severe cases at a rate of 7%, particularly among those with influenza, who experienced increased ICU admissions and longer stays. Comorbidities like cardiac or pulmonary diseases intensified severity, significantly affecting patient outcomes.
1. Study involved 516 pediatric patients hospitalized for viral symptoms. 2. Severe disease rate was 7%, particularly in children with influenza. 3. Chronic conditions increased severity and ICU admissions. 4. Most common pathogens: rhinovirus, adenovirus, influenza, coronavirus, RSV. 5. Coinfections occurred in 40% but did not impact severity. 6. ICU admission rates were higher for influenza (12% vs 2%). 7. Average hospital stay: 8 days for influenza, 6 days for others. 8. Age did not independently affect severity outcomes.
