If we're talking full on PPE, as long as you can put it on and take if off properly, it is 400% full-proof. Its one of the ways the Chinese finally got it under control in Hubei, their staff would work 4-6 hour shifts in the full gear (basically the hazmat suit stuff) with adult nappies included as you weren't supposed to get out of it when you got in.
I think Singapore have essentially avoided HCW Covid-19 as well, as have some hospitals in Italy by having the full and appropriate PPE.
Failing that, something is better than nothing but some workers are feeling pretty demoralised by the lack of it in some trusts right now. It isn't helped that the general morale of the staff has been gradually eroded over the past 5-10 years, which is very sad.
I agree that there would potentially be some casualties from frontline staff, though of course, unlike soldiers, healthcare workers don't sign up to potentially die at work. They are definitely avoidable though. Having said that, despite my criticisms, I acknowledge that the UK is currently in an unprecedented global bidding war for PPE so not everything is their fault in this instance.
Sadly, I think many HCWs have lost their trust of the government over the past 10 years and goodwill towards them and the NHS as a whole has dwindled, which doesn't help matters. I hope this changes soon as I genuinely think, for all its faults, the NHS and the idea behind it is one of the greatest things about this country.
Others have said similar already. But I just wanted to say a genuine thank you, to you and your colleagues.
You are appreciated, even if sometimes it may feel you are not. So thank you.
Also specifically, your comments on this thread are especially insightful into what is going on, on the front line, and I am sure they are appreciated all round.
Lastly... I'm loving your schooling of @scaramanga
