Summary

This study follows 1,590 adults who have had COVID-19 to track their symptoms and recovery over three years. Participants complete phone interviews and online surveys every three months. The goal is to describe the range of recovery experiences and identify factors that lead to persistent symptoms, helping to design future studies on long COVID.

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 identify why some people don't fully recover from COVID-19 and guide future research into treatments for long COVID.
What could go wrong
This is an observational study, not a treatment trial. It may not directly lead to new therapies, and results depend on participants accurately reporting their symptoms over time.
