This is something I've been wondering about. There should be detailed information on the government website about hospital admissions so that's another failure there. People are left guessing which is not good enough. For instance, what do you take? Who informs the hospital of your identity? When or how will you get updates? That should all be on the website.
I know it's no good telling you not to worry, but the staff are all devoted to looking after their patients and will ensure he has the best treatment. I hope he will soon be out and back home, and when it's all over he will then be immune to the virus, which is an enviable position to be in.
