Interesting comparison of alpha, delta and omicron waves.
It's a log plot, so equal distance between lines means equal ratio between those measurements.
The graph is normalised to the January '21 alpha peak, so everything else (cases, hospitalisation, ICUs, deaths) is relative to the peak then.
Timeliness are shifted to give the same peak in '21, ie hospitalizations are lagged by 1-2 weeks, deaths are by 3-4 weeks etc, according to how the peaks of each lagged in '21.
Preamble over, what do we see:
Hospitalizations and deaths fell from alpha to delta by a lot relative to cases. This is due to the vaccination programme.
From delta to omicron there's little difference in hospitalisation or death; omicron seems near equally likely to hospitalise or kill you as delta.
What there is a big change in is severe disease needing ICU - the gap between cases to icu admissions widens a lot.
ourworldindata allows you to make your own plots of this sort now, but I've not tried myself. Perhaps the "South Africa Data was ignored" crowd should try it.
From Paul Mainwood on twitter who explains a bit about why it's useful better than I have, I think.
