Despite the severity of respiratory syncytial virus (RSV) disease in older adults, data on its costs are limited. We compared hospitalization costs for 2090 adults aged ≥ 60 years hospitalized with RSV or influenza by assigning direct health care costs. Hospitalization with RSV was associated with longer hospitalization and increased frequency of diagnosis-related groups for pulmonary complications, resulting in costs at least as great as those for influenza ($16 034 vs $15 163; 95% confidence interval for the difference, -$811 to $2547). Awareness of RSV disease burden in adults is needed to facilitate vaccination and treatment when they become available.
