If someone has a positive test result, they DO have covid, so,we can’t be reporting more cases than there actually are.
I had assumed that the results included LFTs - and as we’ve all been advised to do LFTs before mixing with others and before all our Christmas and New Year plans, it seemed logical,to me that all these extra tests would have picked up a number of cases where the person has no symptoms - so if they hadn’t followed the advice to test before socialising, they wouldn't have known they had it.
I also think we should be dividing the hospital cases and deaths to differentiate between those who are admitted due to/die from covid from those who are admitted to hospital or die from another cause but are found to have covid on admission (but the covid has no effect on their illness or treatment).
At the moment, if I tested positive for covid today and then, once my isolation was over, I went out and was knocked down by a bus and died in hospital, I think I would be counted in the covid statistics, because I had died within 28 days of a positive test. Or if I was admitted to hospital having had a heart attack, and tested positive for covid on admission (I think they are testing everyone who is admitted), I think I’d be counted as an admission with covid - and again, if I died within 28 days of the test, I’d be counted in the stats.
It is the difference between admitted due to and admitted with, and died with and died from - if that makes sense.
