My understanding is that we are meant to be testing twice weekly with lateral flows. We haven’t been doing this. In real life I don’t know anyone who is doing this.
I tested my youngest a few weeks ago when she had a temperature and it was positive. But I only tested her because she had symptoms. We tested in the couple of weeks following that (following negative PCRs) and we never did get it (somehow!) but now we are not testing any more.
I just don’t really want to go looking for it, in all honesty. From where I am it looks like a lot of people are doing the same.
