What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This study collects blood and nasal secretions from up to 2,000 people with COVID-19 to learn why some get very sick while others recover easily. Researchers will also track long-term symptoms like fatigue and brain fog. No treatments are tested—the goal is to gather data to guide future countermeasures.

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 clarify why some people get severe COVID-19 and others don't, and help develop better treatments or vaccines.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to any direct medical advances, and results may take years to apply.

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

In addition, persons who have had a significant exposure to a patient with COVID-19 (contact at distance of less than 6 feet without personal protective equipment) and have remained asymptomatic for 14 days following exposure will be recruited.
