I think it's confusing. The home testing with LFTs has particularly confused the issue, as a lot of people (the majority?) think they can now use them if they have symptoms instead of a PCR.
The symptoms aren't clear: some people think "a continuous cough" means a constant cough.
I have advice from a "trusted" source to only test if you have both a cough and a fever, not one or the other.
I remember when the schools went back last year, people, especially parents, were being urged not to test if it could be a cold or flu. There were lots of posts on social media comparing symptoms, lots saying that if there was a runny nose/sneezing/etc., it wasn't covid even if the other symptoms were there.
We know now that the three symptoms that we are supposed to get tests for aren't even the main symptoms. People with the new main symptoms don't qualify for a free PCR test (unless they have the three listed symptoms).
Home LFTs aren't very good. There are a lot of false negatives.
It has been very confusing. The whole thing has been confusing, especially with the constantly changing guidelines. I have spoken to very well educated, knowledgeable people who have been completely lost with the rules.
