Thank you so much keberoxu. We've had a lovely weekend zooming around our area of Norfolk, having nice cups of tea and doing our supermarket shopping. Husband has two weeks' holiday from his school cleaning (Easter end of term), and I can see he's going from strength to strength. One of his brothers, Nana, and two sisters Hazara & Fatmata have been messaging him, rather worried of course. He's reassured them, and all is well. I'm feeling completely normal now (Husband jokingly says I'm never really 'normal', hee hee)
I think it's prudent if people keep some lateral flow tests in the house to check if they've caught the Lurgy. The symptoms are very like a nasty head cold.
