Presented at the European Respiratory Society (ERS) International Congress 2026, this poster explores the demographic and clinical characteristics, treatment patterns, and outcomes of adults hospitalized with severe acute respiratory infection (SARI) across Europe.

Drawing on data from more than 7,700 medically vulnerable adults enrolled through the id.DRIVE Network, the analysis compares patients hospitalized with influenza, respiratory syncytial virus (RSV), SARS-CoV-2, and other respiratory infections.

The findings highlight important differences in patient risk profiles, clinical presentation, treatment approaches, and outcomes, providing valuable insights for researchers, clinicians, public health professionals, and vaccine stakeholders.

Key findings

• Influenza was the most commonly identified viral pathogen among hospitalized patients.
• Patients with RSV and SARS-CoV-2 were more likely to have multiple chronic conditions.
• Distinct differences were observed in respiratory support requirements and treatment patterns across pathogens.
• In-hospital mortality remained substantial across all major respiratory viruses.
• Integrated SARI surveillance can provide valuable insights into disease burden and outcomes among high-risk adults.
