The flu went through our house this Thanksgiving. My grand nephew came over. He was feeling run down but thought it was from heavy cardio exercises for wrestling. Next day he was in ER. Diagnosed with upper Respiratory infection. His grand mom got sick on Saturday and she spent Sunday in ER. They did give her tests for covid / flu. Came out as flu. She did get the flu shot but only a week ago. I got the flu shot the beginning of Nov and so far not having any symptoms. It is a nasty version this year. Vise like headaches and coughing so much the stomach hurts. You get it suggest you go in for treatment available ( steroids, breathing treatment,etc.)
