It can only be a pandemic if there is a human to human transfer. Virologists say it isn't likely to mutate enough to do that. Still, if you can get it from a cow, will your pet dog be next?
As likely as any other flu, which is basically guaranteed. I doubt it will become a 2020-style shutdown though, purely because that would be unpopular
It's not "basically guaranteed". H5N1 has been around for a while and was never really considered a serious threat before.
And a 2020-style shutdown would be the least of everyone's worries if this thing does blow up. The fatality rates in humans is around 40% or so. At that rate, you're talking about at the very least a complete breakdown of society as we know it, if not a full-blown extinction-level event.
Around here when swine flu went through the country we basically lost the whole pork industry because the first priority was to eliminate the disease. Does the US want a pandemic to be named after them? Because it seems to head in that direction. I think Freedom Flu is a pretty catchy name personally.
