Nobody is immune by race. Only pure serendipity will determine the very, VERY few who are immune. Won't be much common cause between them either. Just something a little different about them that would take decades of research to figure out if ever.
It will rip through every nation eventually. Economies will crash and most systems of order will implode. Only one question to answer now: Will this make humans extinct? The virus itself doesn't have to do all the work. Nuclear facilities cooking off, Deadman switches activating resulting in nuclear launches and hundreds of different bioweapon releases. Labs abandoned and containment fails. We could get those follow up disasters with just a 20% fatality rate and any R0 north of 3.
It's obviously out. Not obvious yet is its fatality rate outside of China. Let me also clear up y'all's silly notion that fatality rate is a static function. If infections overwhelm capacity, that death rate can climb WAY up REAL fast.
At the VERY least, this is the start of the biggest economic depression in human history. That's if this virus just magically disappeared today. Enjoy the last of normal life or possibly any human life.
