I know, from experience, that all the colds, flus and other viruses that were almost non-existent over the past year due to social distancing, are coming back with force. It's very possible that they actually have RSV or influenza. We need to be careful not to blame Covid for every symptom as we move into the fall and winter months. I guarantee you the MSM will be blaming Covid on every stuffy nose to fear the public and get ratings.
Edit: My kids are STILL clearing out from the parainfluenza virus (can cause croup) going around with kids this summer...very unusual to hit in July-Aug timeframe. Anyone could've called it Covid (started with sore throat, then fever for a couple days, then sinus craziness, now coughing), but they were tested and negative.
