In the UK, they will not be able to. The state of the bed situation in Glasgow alone, I'd hate to see what will happen if it continues to increase. The NHS is on it's knees as it is.
I think delivering home testing kits where people can test themselves and self-quarantine if need be is a good idea. Granted, this comes with it's own logistical challenges, but the premise remains. The Royal in Edinburgh has a drive-through testing centre where you present if you feel unwell and may have had contact. Someone in a HazMat suit comes out, swabs you, takes details and off you go awaiting the results as you self-quarantine. This seems sensible to me (rather than sitting in a waiting room with other people and potentially exposing others).
With regards the mortality rate, the reason I stated my opinion was because I read quite a lot of fear-mongering on social media and news outlets, which, in turn, panics people. They constantly use relative risk figures to scare people. I'm not saying that we should be blasé about this at all, but it's important people try and think about things logically before buying shares in Andrex.
I've seen folk stockpiling toilet roll, pasta, hand sanitiser. One lady I saw had 6 or 7 bottles of the stuff. Its infuriating. It's also frustrating me that sport is being so slow on the uptake, F1 in particular.
