So in the last week I met up with a family for something. The whole family had 'a cold', and one of them was coughing. But they had taken lateral flow tests, so were confident it wasn't covid
I had to point out that if you have symptoms you need to get a pcr test. They were actually quite embarassed when I pointed it out and said the symptoms had snuck up on them and they hadn't thought about it enough. It got me thinking about the covid cases that might not be getting tested at the moment. People might be confusing it for a cold and not worrying about it. The symptoms might be quite mild because of vaccination (this family was double jabbed) so people are more inclined to dismiss it a cold. And if this family were using lfts to test mild symptoms then probably lots of other people are too, and getting false negatives.
