Incidence of Respiratory Syncytial Virus-Associated Hospitalization Among Adults in Ontario, Canada, 2017-2019.

ABSTRACT:

Background

Respiratory syncytial virus (RSV) causes substantial morbidity and mortality among adults. Given recent RSV vaccine authorizations, data on groups at highest risk are needed to support vaccine program decision making.

Methods

We identified adults aged ≥ 18 years hospitalized with laboratory-confirmed RSV and hospitalizations with RSV-related diagnostic codes in Ontario, Canada (2017-2019). We calculated incidence of hospitalization with 95% confidence intervals (CIs) using Poisson regression stratified by demographic and clinical risk factors, and substratified by age. We reported secondary outcomes including the proportion of individuals with fatal outcomes.

Results

Over 2 respiratory virus seasons, we identified 3928 RSV-associated hospitalizations. Incid
