From my experience there’s a bigger delay than people realise, if you account for an average 10 days of being asymptotic then generally 2 weeks before a persons condition deteriorates enough to require hospital admission...ICU treatment can be anytime from a few weeks to longer.
I’d also say that many in the shielded category most likely to experience severe disease/death, myself included, who are lucky enough to still be working from home (but unlucky enough to be most likely to experience severe disease
) are still keeping physical contact to an absolute minimum.
Just another perspective to consider.
