Fever clinic tracking of acute respiratory infections

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective cohort enrolls adults presenting to a fever clinic with fever judged by their doctor to be caused by a respiratory infection. At enrollment the team collects clinical symptoms, laboratory parameters, chest imaging, and routine blood samples. Participants are followed over time to document disease progression, complications, treatments received, and longer-term outcomes. No experimental interventions are given and all care is provided by the treating physicians, allowing capture of real-world clinical course and factors linked to outcomes.
