I would be absolutely shocked if we don&amp;#x27;t end up having our lowest impact cold and flu season in decades this year.  That isn&amp;#x27;t to say the grandparent comment is correct, just that you can&amp;#x27;t really use a comparison from prior years as an indication of how many people will get a cold this year.</text></comment>

It sometimes feels like I have cold symptoms more days than I don’t. I currently have cold symptoms. If I had to isolate every day I had a cough, sore throat, congestion, or sneezing, I’d be under house arrest most of the year. I think it’s vitally important that we have accurate COVID tests that can definitively distinguish a case of the cold from a case of COVID.</text></comment>
