Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older who are admitted to hospital (or in the ED with expected admission) for suspected or confirmed acute infection with symptom onset within the past 30 days and who can provide informed consent (or have a surrogate to consent) are appropriate candidates.

Probably not a fit

Individuals who are currently imprisoned, receiving only comfort/end-of-life care, unable or unwilling to participate, or whom investigators judge participation is not in their best interest are not eligible and would not be expected to benefit.

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

What this trial studies

This prospective, longitudinal observational protocol enrolls adults admitted to hospital (or in the emergency department with expected admission) for suspected or confirmed acute infectious diseases within 30 days of symptom onset. Participating sites collect clinical data, laboratory results, and biospecimens over time without providing experimental treatments. The design covers respiratory and non-respiratory infections, established infectious diseases, and emerging pathogens. Generated data and samples are intended to characterize disease course and biology and to inform the selection and design of future interventional trials.

Why it matters

Potential benefit: If successful, the collected data could speed identification of risk factors and lead to better-targeted treatments and management strategies for future patients with acute infections.

How similar studies have gone: Similar observational efforts were essential for early knowledge about H1N1, SARS-CoV-2 (COVID-19), and Mpox, so this approach has a precedent of providing useful insights.
