This post, a week old today, updates us about the #omicron variant of #covid19 . Increasingly it seems that it may more mild than the Delta variant — but that is uncertain; perhaps the low percentage of infected hospitalised in South Africa is because of pre-existing immunities, or because it infects more people in their twenties.

Reason to worry: even if milder, it's much more infectious, so there will be a spike in hospitalisations.
