Summary

This observational study will enroll 1,500 adults hospitalized with acute infections across the globe. Researchers will collect medical data and biological samples to better understand how these infections progress, what factors affect recovery, and how to design better clinical trials in the future. The study does not test any new drug or treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could help doctors better understand acute infections and design more effective treatments and clinical trials for future outbreaks.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly test any new drug or therapy. Results may take years to influence patient care.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Participants will be enrolled at study sites globally. Study personnel at the enrolling site will confirm eligibility and obtain consent prior to beginning study procedures. Signing of the informed consent document signifies study entry and Study Day 0. The study population includes adult patients admitted to a hospital with a suspected or confirmed acute infection. All participants will meet the eligibility criteria below. Specific studies executed with this master protocol may narrow the eligibility criteria to a more specific population (that is, a subset of patients who meet the eligibility criteria in this overarching protocol).

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥18 years old * Admitted to hospital (or in an emergency department with anticipated hospital admission) for the management of a suspected or confirmed acute infectious disease. * Onset of symptoms of an infectious disease within the past 30 days. * Informed consent for study participation by the participant or a surrogate decision maker if the participant lacks capacity for consent. Exclusion Criteria: * Current imprisonment (this does not include quarantine for an infectious disease). * Patient undergoing comfort care measures only such that treatment focuses on end- of-life symptom management over prolongation of life. * Expected inability or unwillingness to participate in study procedures. * In the opinion of the investigator, participation in the study is not in the best interest of the patient.
