Denmark has published an omicron report in English:
files.ssi.dk/covid19/omikro…

among 2,471 omicron cases, 27 have been hospitalized

as @infoseepage noted, there is exponential growth in omicron cases, so most of the Danish cases were recently identified, and insufficient time has passed for such cases to require hospitalization

so this is an underestimate of the % of omicron cases requiring hospitalization

@Infoseepage Today’s omicron report from Denmark compares % of cases that require hospitalization for delta vs omicron. It is HIGHER for omicron, and most of Denmark’s omicron cases were just diagnosed, meaning insufficient time has passed to require hospitalization:

@Infoseepage here’s the age distribution of omicron cases in Denmark. they skew young, so this raises questions about what will happen when omicron spreads to the elderly:

@Infoseepage This table suggests that Denmark may already be seeing nosocomial spread of omicron (9 of the omicron-related hospitalizations tested positive 48+ hours after admission):

I think we need a new letter/push for airborne precautions in hospitals

@Infoseepage @DFisman Today’s omicron report from Denmark finds a drop in the % of omicron cases requiring hospitalization:

to be clear, I was NOT arguing yesterday that omicron is more severe than delta but that we should assume virulence is similar to previous variants.

Also, you can see from this report that omicron’s doubling time has risen. Discussed here:

initial 2-3 day doubling time may have been due to founder effects. also restrictions have been instituted

but large transmission advantage still a big concern
