SARS-CoV-2 Omicron VOC Transmission in Danish Households

1 Abstract

The Omicron variant of concern (VOC) is a rapidly spreading variant of SARS-CoV-2 that is likely to overtake the previously dominant Delta VOC in many countries by the end of 2021.

We estimated the transmission dynamics following the spread of Omicron VOC within Danish households during December 2021. We used data from Danish registers to estimate the household secondary attack rate (SAR).

Among 11,937 households (2,225 with the Omicron VOC), we identified 6,397 secondary infections during a 1-7 day follow-up period. The SAR was 31% and 21% in households with the Omicron and Delta VOC, respectively. We found an increased transmission for unvaccinated individuals, and a reduced transmission for booster-vaccinated individuals, compared to fully vaccinated individuals. Comparing households infected with the Omicron to Delta VOC, we found an 1.17 (95%-CI: 0.99-1.38) times higher SAR for unvaccinated, 2.61 times (95%-CI: 2.34-2.90) higher for fully vaccinated and 3.66 (95%-CI: 2.65-5.05) times higher for booster-vaccinated individuals, demonstrating strong evidence of immune evasiveness of the Omicron VOC.

Our findings confirm that the rapid spread of the Omicron VOC primarily can be ascribed to the immune evasiveness rather than an inherent increase in the basic transmissibility.

要するに・・・

Death汁未接種の場合はオミクロン株自体の感染力はデルタ株と比較してもそんなに変わってない（＋１７％）わけです。

でもDeath汁二回接種の場合は＋１６１％。

Death汁三回接種の場合は＋２６６％。

オミクロン感染急拡大の原因はDeath汁接種者の防御力、即ち自然免疫の急低下ってことです。（爆ｗｗｗｗｗｗｗｗ

オミクロン株はDeath汁接種者を主なターゲットの感染先として急拡大してる変異種ですな。（爆ｗｗｗｗｗｗｗｗｗｗ
