It's scaremongering in order to make the public aware that this is a dangerous, unknown virus which can kill.
80% will alert people to sit up. Of course, not everyone will die ....... nor will everyone within that 80% get the virus. Possibilities then.
Wiping surfaces is important anyway. HOT SOAPY WATER. JAY-cloths which can be burned or put into a hot wash after use. Keep a load of used cloths in a bin with a lid and put on overnight? They dry quickly enough. A good quality washing powder is recommended by local health workers. Wiping car handles, steering wheels, the pumps at petrol stations, toilet doors/flush push handles; I sat in a garage last week and not 1 person wiped the key pads nor used gloves B4 paying for fuel
I think that those over 70 who are active: i.e. Men Sheds, visiting their elderly relatives, i.e. parents : should be allowed out - driving to and from those activities and not dropping off in the store will be 1 way of keeping up morale as well as making sure that parents are OK.
The NHS has waiting lists for many kinds of results. So this added increase of essential postiive/negative testing in order to chart the spread has been put on hold due to lack of Lab. facilities for a pandemic. I know some patients who have had to wait 3 weeks for a result from breast surgery for example, when my Mum had her lumps removed they were sliced there and then in a specific room; result went to the Surgeon whilst Mum remained under GP and the decision for closure or mastectomy was made. Due to lack of funds, that idea went out the window! Add to that staff cuts
