2021年11月28日 · On 26 November 2021, WHO designated the variant B.1.1.529 a variant of concern, named Omicron, on the advice of WHO’s Technical Advisory Group on Virus Evolution (TAG-VE). This decision was based on the evidence presented to the TAG-VE that Omicron has several mutations that may have an impact on how it behaves, for example, on how ...

“For omicron, there are very limited data on this,” Bollinger says. “But, so far, the answer appears to be no. We will know more about this in the coming weeks.”
According to Bollinger and Ray, this is the most important question, and with so little data, a lot is still unknown. “My own expectation is that being fully vaccinated, including boosters, will still provide a reduced risk of hospitalization and death,” Bollinger says. “In the weeks ahead, we will learn more about how well the antibodies induced b...
The available commercial diagnostic PCR (polymerase chain reaction) and antigen COVID tests still appear to work to identify the omicron variant. We will know more in the coming weeks about how well the rapid at-home tests perform to detect the new variant.
2021年11月26日 · The B.1.1.529 variant was first reported to WHO from South Africa on 24 November 2021. The epidemiological situation in South Africa has been characterized by three distinct peaks in reported cases, the latest of which was predominantly the Delta variant.

2021年11月28日 · 2021年11月26日，根据世卫组织 SARS-CoV-2病毒进化技术咨询小组 （TAG-VE）的建议，世卫组织将B.1.1.529变异株命名为奥密克戎（Omicron），并将其定为需要关注的变异株。 世卫组织的这一决定基于该技术咨询小组获得的证据，并考虑到了奥密克戎的多种突变可能会对该病毒行为方式产生影响，例如可能会对其容易传播的程度或所致疾病的严重程度产生影响。 以下是目前已知信息汇总摘要。 目前对奥密克戎的认识. 南非以及世界各地研究人员正开展研究，以进一步多方面了解奥密克戎，并将继续分享研究结果。 传播能力 ：目前尚不清楚与德尔塔等其他变异株相比，奥密克戎是否传播能力更强（例如是否更易在人与人之间传播）。 在受该变异株影响的南非多个地区，检测呈阳性人数增加。
