The good thing about the cough analysis is that it provides a direct path to the lungs, rather than having the sounds pass through the chest. This was (part of) the original basis of taking the cough analysis approach, as there's more information.

The idea of monitoring the breathing and persistent monitoring would/could be taken care of by a wearable like that mentioned in the announcement on the 29th of May. This was for "monitoring patients with chronic disease 24/7 over extended periods".
So yep, effectively like a stethoscope and doctor attached walking around with them all the time.
