I’m not so sure on that one. Some of the stuff I read suggests once this thing gets in full bloom, depending on the overall health of the person who has it, death is not that far removed. High death tolls would not surprise me at all on this stuff.
The fatality ratio requires an accurate number of infections which are certainly undercounted. We don't know by how much they are undercounted. The mild cases are probably not reported. Also need to know what other conditions the deceased had. So far I have not heard of healthy people dying from this.
