Regarding the talk about care homes - really nasty situations from the sounds of it.
I'm afraid its always been like that in many care homes, its hard work for the staff, little pay or other rewards for them, and 'Gods waiting room' for the residents.
Because of the economics of running care homes and the layouts and schedules needed to run such places, any contagious disease spreads quickly. If they know about it in advance management/ staff can take preventative action, but they will never usually carry enough PPE or medicines stocks to resist an onslaught from something like Covid-19.
Care homes are and have been for a long time the most vulnerable places with most residents there because there is no where else for them to go and staffing levels are usually the bare minimum, because for the most part, the pay and conditions of service are poor.
This situation as been highlighted by Covid-19 and you would hope after its over somethings will change... but don't hold your breath.
End of life care, be it for those with chronic illness (in hospices/nursing homes) or those simply suffering from ageing (Care homes) is not front of the queue for public investment... and will be even less so for the foreseeable future as the economy will have taken a major hit.
