I genuinely think local authorities don't want to make decisions in how to manage visiting with 'risk'. The solution is as already laid bare -appropriate use of PPE and testing. Good use of PPE breaks the chain of infection as well as specific infection control measures, if it didn't hospitals would have ceased to function months ago. I feel that much of the decision making is not about public interest but more about dodging bad publicity if a care home does have a rise in cases. And what happens when cases rise despite lockdown? The bottom line is that whatever we do there is always going to be a chance of spread. The logic of closing a care home because another care home in the area has had cases of coronavirus baffles me! Lets see, should we close a hospital because another one in the area has a rise in coronavirus cases? Yes lockdown if it is directly pertinent to do so.
Public safety is paramount, I don't disagree with that at all, being a member of the public, but the layers of beaurocacy beat the hell of sensible decision making.
