This is a sensitive one that I've been claiming since November when South Africa responded to the UK blocking flights from there:
Omicron could be the best thing that happened, relative to the current situation ( delta at the time and multiple countries were having a lot of cases of delta).
Currently both of the "best possible scenarios" are happening but need further data.
- less severity and less hospital duration
- replaces delta
The big downside is the stress on first line workers ( eg. Doctors)
