In a cohort of 1,700 patients with RV HAI, patients had longer mean lengths of stay (e.g., 21 days vs. 5 days in community-acquired cases). These patients were older, had pre-existing respiratory disorders or were immunosuppressed and faced greater RV HAI risk. They were also likely to exhibit typical respiratory infection symptoms, which could delay diagnosis.

RV HAIs are also associated with significantly higher mortality compared with community-acquired cases, often with several-fold greater risk. Among patients who acquired influenza in hospital, 21.7% died compared with 4% among patients with negative test results. So, roughly 1 in 5 hospital-acquired influenza patients die in hospital, compared with about 1 in 25 in similar hospitalised…
