Thanks Clo. I think our previous vaccines and boosters gave us some immunity, protecting us from becoming seriously ill. I started with a sore throat and runny nose late Thursday. All I wanted to do on Friday was sleep. Which I did for roughly 30 hrs. Mum was a day behind me with her symptoms and slept all day Saturday. I think the long period of sleep was due to our immune response. Since then our primary symptoms match those of a head cold - stuffy head, sore throat, dry cough - plus being extremely tired. We're keeping quietly housebound. She has a couple dr appointments scheduled this week. As soon as their offices open I'll call to reschedule. We were to meet a friend for breakfast tomorrow, I texted him Saturday to cancel. Contacted a couple places we go to regularly for breakfast to let them know they will not see again before Christmas. Didn't want them to worry, worst part is each Christmas we take them trays of our homemade cookies and peanut brittle. The treats were all made before we got sick so we'll deliver them next week on the 2nd, 3rd or 4th days of Christmas instead of a bunch of silly birds.
