NSW is the ideal setting to measure the severity of Omicron, and it is showing a CFR for Omicron that is <1/2 of Delta
Five reasons it's ideal:
*Prior infection is irrelevant (~2-3% of NSW is prior infected)
*Delta cases were steady through Nov, making a stable baseline CHR1/15 pic.twitter.com/qVT0QxMzSl

That’s about what I expected to see with Omicron. I said 50-80% less severe here. My guess (with no data) is that it also causes even less long Covid than that (80-95% less). Time will tell on that one.
