I think tests are now easier to book, and a lot of workplaces now insisting on having them (we now have to have a test weekly). Back in June, we were not getting tested at all - and I work in social care.
I think many people are now getting tested. Either because of work, travel or as in my sisters case - hay fever symptoms! Her employer sent her for a test on Friday, because her eyes were swollen and she had a blocked nose. No fever, didn’t feel ill - but they wouldn’t have it. She doesn’t seem to respond to antihistamines, so they will need to accept at some point, that people do just get hay fever.
