@Lightsabre, thanks. I'm worried I've already spread it thanks to my early symptoms being mild/inconsistent, but I've isolated as far as possible in a small house with two kids since it became obvious this week.
I should perhaps have been more cautious, but this highlights the concerns about the ongoing promotion of cough and fever as being the symptoms - too many people will start with different ones that can be easily explained by other things, such as hayfever in my case, and unwittingly spread it. Not to shift the responsibility from myself at all, but it does seem to be a potential issue.
@Jouley, please don't worry about tonight's sleep, I've found that a bad night doesn't necessarily follow a bad night. I had a decent night last night propped up with pillows, even though I'd spent the whole day worrying about it.
Hope everyone who's entitled gets a test and gets the answers they need
