A hybrid of Omicron variants BA.1 and BA.2, XE is 10 percent more transmissible than the BA.2 subvariant and could be the most dominant strain of the virus in the near future.

Currently. BA.2 — or the "Stealth Variant" — represents nearly 86% of all sequences cases, the WHO says.

The BA.2 subvariant has caused surges in Asia and Europe, and could cause another one in the US, Reuters says. More research is still needed, the WHO said.
