The highly transmissible Omicron variant of the SARS-CoV-2
virus - the most common form of which is known as BA.1 - now accounts for
nearly all of the coronavirus infections globally, although dramatic surges in
Covid cases have already peaked in some countries.
Scientists are now tracking a rise in cases caused by a
close cousin known as BA.2, which is starting to outcompete BA.1 in parts of
Europe and Asia. The following is what we know so far about the new subvariant:

SUBVARIANT
Globally, BA.1 accounted for 98.8% of sequenced cases
submitted to the public virus tracking database GISAID as of Jan. 25. But
several countries are reporting recent increases in the subvariant known as
BA.2, according to the World Health Organization.
In addition to BA.1 and BA.2, the WHO lists two other
subvariants under the Omicron umbrella: BA.1.1.529 and BA.3. All are closely
related genetically, but each features mutations that could alter how they
behave.
