Massive new study to track long COVID for years – no treatment, just answers
NCT ID NCT07498504
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will follow over 5,000 adults with Long COVID for two years each to understand how the condition changes over time, who recovers, and what new illnesses may develop. Researchers will focus on brain fog, heart and lung problems, and chronic fatigue. No drugs or treatments are being tested – the goal is to gather knowledge to guide future care and public health.
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 reveal why some people recover from Long COVID while others don't, and identify new health problems that may appear years later.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead to any direct therapies, and results may take years to influence care.
