Observational Study on Long-term Impact of COVID-19

This study, called LIINC, is looking at the long-term effects of having been infected with the novel coronavirus (COVID-19). It's for people who have already recovered from COVID-19. Researchers want to collect samples and information to understand how the virus affects people over time, especially focusing on how different people's immune systems respond. They are not testing a new medicine or treatment. Instead, they are gathering information to create a resource for future research. The study aims to enroll about 800 participants and is currently unclear if it's recruiting. To join, you must be at least 18 years old and have a documented history of SARS-CoV-2 infection.
