This SF version is not that different from 'standard' seasonal human flu. That's why it's only now being 'discovered' in the US. It's been circulating for a while, and making folks sick, but hasn't killed (AFAIK) anyone north of the border. It's far more established in Mexico, and more infections = more deaths, mostly from people in poor condition. Getting it would suck, but you'd likely get over it, just like any other flu.
That said, it could mutate and become something nastier. Or not.
No need to panic yet.
