Ms Sarah O'Connell:

Yes. There have been tens of thousands of research studies done on long Covid looking to find biomarkers that can lead to a clear way of diagnosing long Covid. Obviously, the inability to diagnose based on a test and the fact we have to diagnose based on exclusion is a big problem. I think we are getting to that point, but it will take time. There are research studies that show clearly there are very specific problems with patients and ways in which their bodies are not functioning.
