Yes, sorry from me too Carol.  I discussed this with OH but I had seen it before.  It really hits home how easy a virus of this sort can get out of hand.
The 'It's only flu' brigade are really starting to annoy me.  I have to admit I was in that group a few weeks ago but I recovered.  People should be doing as advised or it will be a lot worse than it needs to be.
