A genuine question to those of you who are CEV. I hope not to sound insensitive but I’m struggling to understand why this virus is more of an issue than all of the others and needing of such extreme measures where none have ever been in place for you before for any other virus.
Does a common cold or the flu not also pose you similar risks? Or is it just covid?
It's not insensitive at all; I'm CEV and totally happy to answer questions like this.

For me, all viruses are a risk and I had to be extremely careful before Covid too. I already wore masks and avoided certain activities because of the risk of infection - obviously I'm not expecting for things ever to be totally safe for me. That's just my body and I accept that risk is part of my life, like other aspects of being so unwell.
I've actually just had a non-Covid infection (technically still got it), and have stayed gone throughout as part of a complex weighing of risk - despite the problems meeting some criteria of being life threatening (sats below 90, poor breathing, etc). It gets complicated when you have a lot of issues and are juggling them as best you can, with advice from different doctors. I have home oxygen and a lot of monitoring stuff - I am already working with a different 'normal'. It does of course differ a lot depending on your CEV experience, as some are CEV and well (working, sporty, etc), while others are disabled - it doesn't make the first group any less vulnerable! But might cause us to feel a bit differently, I would guess.
The biggest change / most dramatic impact for me has been my own doctors talking about seeing Covid patients (not personal details, of course), and seeing how sincere they were in urging me to continue shielding. I knew I was at risk from flu, etc, but have been having flu jabs for years - though I was effectively shielding during swine flu too. It just wasn't called that.
