SANTA CLARA COUNTY, Calif. (KGO) -- The World Health Organization is asking scientists and governments to monitor and study the new omicron sub-variant, referred to as BA.2.

Doctor George Han is the county's Deputy Health Officer and Infectious Disease and Response Branch Director.

"Early indications say that it probably behaves just like the BA-1 omicron lineage, but again it's probably too early to tell, because of the small number of cases that have occurred so far," Dr. Han said.

Officials aren't releasing any information about the two people who tested positive for this sub-variant.
