Mayhem, panic, cats and dogs living together

Right now, I'll bet the British are glad they kept their antiquated quarantine laws. The bird that was carrying the virus was in quarantine. Time to go vegetarian?

One month to go before we'll be in Britain. Apparently, the H5N1 won't be dangerous to humans unless it mutates. 150 million people is a very very big number.

I just read the article more in depth and am confused. Do they think the bird caught the virus from other birds in quarantine (the ones from Taiwan)? Or is there bird flu in S.A. as well?
