RE:RE:RE:My concernTo argue against myself, it is because it is detection and not prevention. We all show up, and the thing goes off, someone has Covid. It works...but if that individual now infected others, the device worked but it did not prevent an infection. Tracing could prevent spreading afterwards though. Now, what I may have heard in one of their presentations, but I am not clear, the BC detects the virus in concentrations too low for actual transmission (hopefully there is solid scientific data on those concentrations). But, if this is true, this needs to be communicated much clearer and emphasized! Hey, if the BC goes off, it doesnt tell you that all in the vicinity may be screwed. It actually raises the alarm at a level that only the individual that triggered it is screwed and if the rest evacuate the area they will most likely be OK. That's how you market a detection device as having immediate, not downstream, protection benefits as well...but it is not a medical device in the sense of destroying the virus. The last demo video I find does not properly balance the depth and focus of content. Too much about the technical stuff, not much in layman's practical application. Clients typically won't care how the guts work as long as they have strong independent confidence that it works.
