I really don't understand this...the WHO has a test for this that only takes a few hours. Apparently the US isn't using it. Wtf is that all about? Yes it'll mutate, but no - it's unlikely to mutate into something more deadly. The common cold has been mutating for thousands of years, every year, and yet it's still just an annoyance. The most lethal threats are the ones that suddenly jump species, like this virus did - we have no herd immunity to them so they spread like wildfire through the human population. We're lucky that this one only kills less than 3.5% of the infected; it could've been much much worse.
