Danish study suggests Omicron subvariant is more transmissible

The BA.2 subvariant of the Omicron coronavirus variant, which has quickly taken over in Denmark, is more transmissible than the more common BA.1 and more able to infect vaccinated people, a Danish study has found.

Reuters reports:

The study, which analysed coronavirus infections in more than 8,500 Danish households between December and January, found that people infected with the BA.2 subvariant were roughly 33% more likely to infect others, compared to those infected with BA.1.

Worldwide, the “original” BA.1 subvariant accounts for more than 98% of Omicron cases, but its close cousin BA.2 has quickly become the dominant strain in Denmark, dethroning BA.1 in the second week of January.
