Clinical Features and Gene Expression Patterns in Adults Hospitalized With Respiratory Syncytial Virus and Human Metapneumovirus Infection

Although RSV and HMPV are closely related viruses, we found differences in the clinical features of adults with HMPV patients presenting with more flu-like symptoms and viral pneumonia. Peripheral blood gene expression of hospitalized HMPV-infected patients also differed compared to those hospitalized and infected with RSV.
