Quick follow up from me. I never got a respiratory virus. Although I had some weird issues this week with being dizzy and not much appetite. Since no respiratory symptoms developed, I would say with 95% confidence whatever this was it was not contagious.
My issues may be totally unrelated, stress, old age, whatever. Just to reiterate, I only brought this up because I believe in reviews with full disclosure. I would hope if any of you notice something similar you would mention it as well. If we can't use each other's experience to help enhance our own and keep us safe, why bother?
