Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with community-acquired respiratory tract infection and able to provide quality sputum or saliva samples.

Probably not a fit

Patients who do not have RSV or whose illness is mild and resolves without complication may not directly benefit from the study findings.

What this trial studies

This is an observational study that will serially collect specimens from adults with community-acquired respiratory tract infections to understand the burden of RSV in the adult population. It aims to fill knowledge gaps about RSV impact, including hospitalizations and complications, in contrast to the well-described pediatric data. The study is led by the Chinese University of Hong Kong and conducted at a single site. No antiviral or vaccine intervention is being tested; rather, the study characterizes disease burden using observational methods. Eligible participants are adults 18 years and older with respiratory symptoms, and those unable to provide high-quality sputum or saliva are excluded.

Why it matters

Potential benefit: If successful, results could help policymakers decide on RSV prevention strategies for high-risk adults and guide future research and resource allocation.

How similar studies have gone: Prior research has shown RSV contributes a notable burden in adults, though data are heterogeneous; this study builds on that observation with systematic sampling in Hong Kong.
