The Omicron subvariant BA.2 is now dominant in Denmark. This variant of the virus has also been detected in more than 40 countries across the world and is beginning to displace the original Omicron.

Unlocking the mysteries behind Omicron's unique set of mutations will be key to understanding how this virus evolves and spreads — particularly as a tougher-to-detect subvariant called BA.2 is taking off in various countries.

A stealthy version of the omicron variant has been detected in the U.S., but so far, it makes up a very low proportion of the overall cases in the country.

The Omicron subtype has caused concern as it may be better at spreading than the original form of the variant, but little is currently known about it.

BA. 2 has become the dominant form of the virus in Denmark, and at least three cases have been found in the United States.

Initial findings indicate that the sub-variant may be more resistant to immunity.

Even as Omicron infections in the U.S. and have peaked, a new variant on the block will keep health authorities on tenterhooks for now. Called 'Stealth Omicron', it is one of the substrains that emerged with Omicron and is reported to be more transmissible than Omicron itself

The UK Health Security Agency on Friday designated a sub-lineage of the dominant and highly transmissible Omicron coronavirus variant as a variant under investigation, saying it could have a growth advantage.

A sub-variant of COVID-19’s omicron strain called BA.2 looks even more transmissible, but the hope is that it won’t pose a bigger threat than its predecessor.
