Sounds too severe to be COVID if you are vaxxed. I had a 102-103F fever for 2-3 days about 10 days ago, coughing, head cold, etc. Multiple tests negative for COVID. Several others at the ski area had same thing, fever, chills, long lasting cough (I still have it 10 days later) and negative COVID.
Doctor even said it was definitely more severe symptoms than vaxxed and boosted patients he had. He explained vaxxed and boosted patients around here were seeing slight sore throats or even stuff that you would’ve never paid attention to in the past.
Speculated that the high fever was the actual flu as many of us forgot to get that vaccine this year, ha.
