It's a time bomb we've got used to.
The current strain is not infectious human to human so those who work in the poultry industry are the only ones really at risk at the moment and they take special precautions.
but cases keep coming up like this

But the media can only keep interest in such a story for so long whilst there's no human element.
There's only really a major risk if it mutates to be transmissible human to human, nobody seems to really know how likely that is to happen.
If it does It'll be big news and there'll be a lot of fatalities.
