It's hard to know what to say on this anymore, I live in a fairly isolated area in England, and stupidly thought I was fairly insulated, yet my sister has had Covid-19 symptoms (returned from Portugal two weeks ago), rang 111, and they wouldn't test her, my brother's wife has just found out her friend ( a teacher) has tested positive, someone she has seen daily, he was ill 2-3 weeks ago, as was their son, as was I, as was my wife, as was my son, etc, the point is it's just all around us, there is no realistic way of avoiding it.
