5) interestingly, BA2 once popped up months ago briefly in Denmark but then was displaced by Delta last summer. Somehow it’s back - perhaps it is more evasive but slower— but now evasive variant is more competitive? Unclear.

6) I’ve been growing concerned about #BA2 for a while. Denmark ministry of health (SSI) also put out a warning last week it could be more transmissible.

I’m concerned about the new #BA2 sub variant of #Omicron. In the left panel, you see it is surging (light green) to almost half of all Danish 
#Omicron cases—surpassing the old Omicron BA1 variant by a lot. Either it’s much faster transmission or it evades immunity even more.

8) the other bad news on #BA2 is that our old friend, S-Gene dropout shortcut (PCR) test, cannot identify the BA2 sub variant easily—while BA1 #Omicron is easily found these days with SGTF. This might make deciphering BA2 and Delta & other strains harder. github.com/cov-lineages/p

8) Crap, the downplaying of BA2 has begun just like before. All while ignoring Danish data that shows 65% #BA2 dominance!

NEW—3 cases of the new #BA2 subvariant of #Omicron has been found in Texas. But it’s again being stupidly downplayed by @CDCgov saying it’s very low. But it was once low in Denmark too! 
Today—BA2 is now fully dominant in —65% of all #COVID19 now!

9) Virus researcher & chief physician of Danish public health authority says you can get infected with #BA2 subvariant of #Omicron after being infected with Omicron BA.1. ➡️ This is why we shouldn’t risk COVID or chase mass infection. nyheder.tv2.dk/2022-01-21-ny-

10) 1.5x faster — Denmark’s CDC says BA2 subvariant of #Omicron is about ~1.5 times more contagious than BA1 (original Omicron). This makes it much higher than prior estimates and could “extend” the Omicron wave into February, says 🇩🇰 officials. ssi.dk/-/media/arkiv/

I think we better warm to the fact that we will never get in front of this virus. I think long term studies of people who have contracted the virus are in order so we can get a better grip on some the effects. Treatment modalities need to be a focus now.
