The only thing that changed with the "confirmed" numbers between the two sources is that they realised one person hadn't come from the US, so the number decreased from 14 to 13. But the main point is that "confirmed" here doesn't mean confirmed by laboratory tests, which is what goes in that column. See my last post in this section for more. I'm happy to try to explain further if you're still having trouble understanding the distinction after reading that, but it might be best if we carry on the conversation there.
