No doubting its transmissibility now imo, we only ever sequenced 1100 cases of beta in the UK which couldn't compete with Delta. This is a different beast.
I imagine omicron will assert itself a lot quicker than 6 months. The Norway party has now been upgraded from between 50-60 to 80-90 individuals positive after 1 event, astounding transmissibility on a par with measles but airborne.
