BA.2 Omicron Subvariant Gains In Europe, But May Not Change Much

A subvariant that scientists believe is even more contagious than the most common form of Omicron is spreading rapidly in parts of Asia and Europe and is now dominant in Denmark, where nearly all Covid restrictions were lifted last week.

For now, scientists are not expecting the subvariant, known as BA.2, to do significantly more damage than the version of Omicron that remains dominant in the rest of the world, BA.1. But they are concerned that BA.2 could extend the global Omicron surge, because it seems to be even more infectious than BA.1, which was already extremely contagious. The subvariant has been documented in at least 57 countries.
