简要总结
The purpose of this study is to evaluate the positivity rate of respiratory syncytial virus (RSV), influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in high-risk participants presenting with acute respiratory infections (ARIs) in outpatient settings during the influenza/RSV season and to evaluate the association between lower respiratory tract disease (LRTD) and ARI-related hospitalization in participants positive for RSV.
详细描述
Lower respiratory tract infections (LRTIs) are a major cause of mortality and morbidity worldwide with 2.3 million deaths in 2016 alone among all age groups, making it the sixth leading cause of mortality. The current study aims to assess the burden of RSV infections among adult participants presenting in outpatient settings, who are at high risk of complications or progression to severe disease due to their age or pre-existing comorbidities. Regional data from the United States (US), Europe, Middle East, and Asia (EMEA) and Asia-Pacific (APAC) will provide evidence on local RSV morbidity, mortality, medical resource utilization (MRU), standard of care, and quality of life in adults participants. A subset of participants positive for influenza virus and/or SARS-CoV-2 will also be enrolled, to allow for a comparative assessment of disease burden between the 3 viral respiratory pathogens. No study drug will be involved in this study. The total duration of the study for each participant will be a maximum of 3 months (+-1 week) from the date of enrollment. Safety will be assessed in the form of adverse events and serious adverse events related to study devices or procedures and for deaths regardless of causality.
