Addis AbabaAges 18 years+ - NCT06571136Recruiting
Can a breath test detect COVID-19?
This study tests a new device that measures chemicals in your breath to see if it can quickly tell if you have COVID-19. If successful, it could lead to a fast, non-invasive way to check for the virus.
Everett, WashingtonAges 18–70 - NCT06703034Recruiting
Studying the immune response in people who had severe or mild COVID-19

- Yes. Clin2 currently lists 305 recruiting covid-19 studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a covid-19 trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a covid-19 trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
