SWISSAVANS  SARS-CoV-2 Antigen Rapid Test Kit against New Variant Omicron

The spread of the new variant “Omicron” is faster than expected. The countries and regions with reported Omicron cases on the GISAID website have been increased to twenty-one on Dec. 2, 2021. The data only showed the number of submitted sequenced cases, which might be just the tip of the iceberg.

Scientists in South Africa on November 24, 2021, identified a concerning new variant of the coronavirus, whose mutations mark a "big jump in evolution" that is driving a spike in new cases. Hours later, Britain banned flights from six southern African nations, citing the variant. Later this variant was also detected in Botswana, Hong Kong, Italy, Israel, Australia, Germany, France, Switzerland, UK, Netherlands, Canada, Demark, Austria, Czech Republic, and Belgium…


 The variant Omicron, also known as B.1.1.529, is primarily of concern due to the large number of mutations it has in the Spike gene. Many of these variants are in the binding receptor-binding domain and N-terminal domain, and thus may play key roles in ACE2 binding and antibody recognition, which might help it evade vaccines and make it more contagious.
