Know any comparisons vs delta??

19,137 Delta cases in Denmark, also from Table 2 in same doc.

  0.07% fatal, 0.11% ICU, 1.5% hospital
  0.9% Covid-recovered 
  50% double vax, 3% booster
  44% unvax, 3% single vax

That table is extremely useful b/c it tells us it's still too early to tell. Had just a single of the 785 omicron cases died (like maybe they got an unrelated stroke while in the hospital), then that would change the numbers from 0% IFR to 0.12% IFR (i.e. above Delta).

Also, noticed that ICU rate is 3x higher with Omicron (which might also be related to the lack of enough observations).

That said, I really hope IFR is much lower, given all the vaccines, boosters, and previous infections.

> ICU rate is 3x higher with Omicron

Sorry, that was a typo on my part, Omicron ICU should have been 0.13% not 0.3%, fixed now after double checking the source doc, thanks.

The Delta-Omicron ICU rates are similar in this Denmark sample.

What may be of interest is that the proportion of vaccinated people is more important with Omicron cases. It may mean that the vaccine is less protecting against ICU as the rate are similar, and that would be worrying. But we are going to have to wait at least 2 more weeks to get a better picture.

Compared that to flu data from 2018-19 season [1]:

28,908,721 flu cases:

0.09% fatal, 1.3% hospital
