Estimates of the mortality rate vary, but one media source says, “While the single figures of deaths in early January seemed reassuring, the death toll has now climbed to above 3 percent.” This would put itroughly on par with the mortality rate of the 1918 flu pandemic.
It should be noted that the oft-cited case-fatality ratio of 2.5% for the 1918 flu might be inaccurate, and the true CFR could be closer to 10%: https://rybicki.blog/2018/04/11/1918-influenza-pandemic-case-fatality-rate/?fbclid=IwAR3SYYuiERormJxeFZ5Mx2X_00QRP9xkdBktfmzJmc8KR-iqpbK8tGlNqtQ
