As some context, the NHS is the United Kingdom’s national health service — and the UK’s leader is now in a London NHS ICU. Assuming he’s is getting the same treatment as others in the UK’s NHS ICUs — odds of him dying currently appear to be 50%.
Big assumption. Pretty sure he was moved there as a precaution in a way that most others weren’t. And so far at least he’s not receiving ventilation (invasive or otherwise).
