Has Omicron shifted receptor binding specificity away from deep lung tissue?

Could this be why it appears that Omicron is less severe than other variants?
My current Substack article gets into the science behind this new variant:https://t.co/lGBhiC63O5
Is THIS why Omicron is spreading so rapidly? Study claims ultra-infectious variant replicates in airways 70 TIMES quicker than Delta... but it struggles when it reaches the lungs in more proof it may be milder
- Omicron replicates faster than previous versions of the virus in the bronchus
- But it duplicates more slowly in the lungs, according to scientists in Hong Kong
- Study may explain why virus is more transmissible but causes milder illness
The Omicron variant multiplies 70 times faster than Delta in the airways, according to a study which may explain why the mutant virus is spreading at a ferocious pace.
Hong Kong University researchers also found that the new variant replicates 10 times slower in the lungs than its predecessor.
That finding lends weight to the theory that it is milder than the past variants, something which doctors in South Africa have been claiming for weeks.
The researchers exposed lung tissue in a laboratory to the original Covid strain that was identified in Wuhan last year, along with the two variants, to compare how the viruses behave after infection.
Omicron replicated faster in the bronchus — tubes connecting the windpipe and lungs — suggesting people with the strain may be more infectious.
Higher viral loads nearer the throat means people are more likely to breathe out viral particles.
Delta was found to duplicate much more quickly in the lungs, where more of the virus can lead to the most severe illness.
The finding may be the biological clue behind why doctors insist people infected with the strain only suffer cold-like symptoms.

決着が早そうですね。
だからビルゲイツがパンダミックは来年終了すると言ったのか。
生き残るとは言ってないｗ
人類は蝙蝠になるのだw
太ったら発症してしまう

なんか実感してる
今迄生きてて出ない鼻うんこが茶飯事レベル
鼻水が薄ら気づかない程度に出てるんだろうな～ とか
（流石に鼻うんこかっぴかぴだと鼻が痛いので
湯気とかスチーム吸うようにしてる）
恐ろしく寝た時
鼻腔で頑張ってくれてた分のリカバリーっすね と
己と対話っすよww
