Signs of the Omicron variant of the coronavirus have been found in California’s wastewater, officials said, as the number of cases associated with the new variant rose to double digits, including two new infections in Los Angeles County confirmed since Tuesday.

Clues suggestive of Omicron’s presence in the Central Valley were picked up in wastewater samples collected in Sacramento and Merced counties, state epidemiologist Dr. Erica Pan said this week in a discussion hosted by the California Medical Assn.

“We definitely are seeing Omicron across the state, for sure,” Pan said.
