Oh god. So sorry to hear that groovee. What a nightmare, but I suppose good that it has been identified and he is at least now in the right place. 
to you both, and I hope your injuries are recovering too!
On the "how t f is is spreading and how t f can we stop it" front, I saw a thread on twatter earlier about the number of people failing to self isolate, even those with symptoms. Now, I may be missing something, but if we focus energies on anything to stop community spread, it must be this, surely? Why fart around with queues outside greggs of (probably) healthy people when Stuart down the road with a cough and a positive test is still working because he is on a zero hours contract and won't get paid if he doesn't work, and the 500 quid (or whatever) isn't enough to pay his rent and bills. It must be cheaper to pay the full salary (or even 80%, like furlough) of anyone asked to self isolate because of symptoms or as a contact... deliver a wodge of food for however many are in the house, and ensure that people are available to help them with any necessary medicines, take over their out-of-home caring responsibilities and so on. Someone on the thread suggested voluntary quarantine hotels, for anyone worried about passing it on in the household, which isn't a bad idea.
It may be totally impractical and unfeasible, but surely the people we need to keep away from others are those with the virus, or those with some likelihood of having it - not so much someone who wants to pick up a takeaway, or collect some printer paper for homeschooling but otherwise hasn't left the house for 5 days. So if we know 30% (or whatever) of infected people aren't self isolating properly, isn't it a no brainer that we have to focus on those people first?!
