Summary
This study follows 583 adults who recovered from COVID-19 or were close contacts. Researchers will track their health, mental well-being, and immune responses over 3 years to understand long-term effects and whether prior infection prevents reinfection. Participants undergo regular tests including blood work, lung function, and mental health interviews.

What this could lead to
If successful, this study could reveal how long immunity lasts after COVID-19 and what long-term health problems survivors may face.
What could go wrong
This is an observational study, not a treatment trial. It may not find clear answers due to the complexity of long COVID and varying participant experiences.
