This is not your average "feel rough for a few days and dose yourself up with Lemsip" type of flu. If it does (as we are told it will) mutate to become highly contagious between humans, it will be a killer of vulnerable people.

Think of it as you would The Plague. Would you want to perform at a gig where the audience could give you the Plague?   I think not.

(Yes, I know the Plague was not transmitted by human-to-human contact - this is just an example)

In this case, I think the Government would be right in taking stong measures in an attempt to reduce public exposure to something extremely nasty.
