I consider asymptomatic to mean no outwardly visible or detectable symptoms.
I’m not sure that we know enough of what this virus does to say that any given person is completely without symptoms despite being infected.
Just my uneducated opinion though.
CT is a good idea, especially for asymptomatics. Some of whom present with no shortness of breath but hypoxic all the same. Did their infection go straight to the brainstem and suppress reflexes? Would a CT help differentiate whether it’s viral debris in the aveoli or blood clotting (or both) that is interfering with blood flow and oxygenization thru the lungs? There are several companies that produce bed-site CTs which minimize transport and so contain infection better than wheeling gurneys around the hallways. Has this resource been underutilized? (I.e., if this is a cost issue, what was that cost vs that of defective/iffy testing?)
I suggested Brilinta (or its competitor) a few weeks ago as an alternative to heperin. It’s not a cheap drug, $500/mo retail, or a fast drug, but it does work to mitigate clotting and is heart-protective. Surely the company can contribute to a trial or three outside their normal ‘patient assistance’ trials? What does Astra-Zeneca say about the usefulness?
see also Dr. Seheult’s lecture on Diffusion Abnormality. He starts the walkthrough about 11 min in, covering V/Q and Shunting abnormalities, and then contrasts those with Diffusion Abnormality at about 22 min in. It would seem DA is what is happening. With drawings:
