TBH, part of the problem is if you have a mild dose, you don't necessarily have all the symptoms. I'm off work with a viral infection. I didn't have a temperature although I had the same feeling and felt as ill as if I did. I personally, doubt I've had anything other than a strange virus - the combination of symptoms was very strange. However, my doctor saw me and straight away diagnosed a viral infection and banned me from going to work for a week. Must admit, although I go out very little normally, it's been very hard not leaving the house except to the outside bin.
For those above who said good luck stopping them going out, the next step inevitably if spreading continues will be a house arrest style ban. If that gets broken, then probably the National Guard and Marshal law.
