Brief Summary
This prospective cohort study aims to characterize the natural progression and outcomes of acute respiratory infections among patients presenting to fever clinics. At enrollment, patients' clinical symptoms, laboratory findings, and chest imaging data will be collected. Longitudinal follow-up will be conducted to evaluate disease progression, complications, and long-term outcomes. As an observational study, no interventions are involved; all patients receive routine clinical management as directed by their attending physicians. This real-world study design enables the assessment of the natural course of acute respiratory infections and the identification of factors associated with clinical outcomes.
