SACRAMENTO — Gov. Gavin Newsom will quarantine for 10 days after one of his staffers tested positive for COVID-19, according to a spokesperson for the governor’s office.

The staffer tested positive Sunday afternoon, the spokesperson stated. Newsom was then tested and his result came back negative.

The staffer also had contact with other staff members, who were also tested. Their results came back negative.

Newsom’s 10-day quarantine is out of “an abundance of caution,” the statement said. The governor and other staffers were expected to be tested again in the next few days.

Another person in the governor’s office tested positive in October, and the governor tested negative back then.

Last month, members of the governor’s family were exposed to someone who tested positive for the virus. Newsom, his wife and four children tested negative at that time.
