Contra Costa County Confirms First Local Case Of Coronavirus

MARTINEZ (CBS SF) -- Contra Costa County health officials on Tuesday confirmed the county's first local case of coronavirus. Officials with Contra Costa Health Services said the person tested positive on Tuesday afternoon. The county's public health lab conducted the test, which is expected to be confirmed by the Centers for Disease Control and Prevention in the coming days.

The patient, a man over 18 years old, is in isolation and is being treated at a county hospital, but health officials did not disclose which one. The infected person had no known travel history and no known contact with anyone else confirmed to have COVID-19, CCHS officials said.

The patient was admitted to the hospital on Sunday, March 1, said Dr. Ori Tzvieli, the county's public health medical director. The patient has underlying health conditions and is in critical condition. Tzvieli said they wouldn't release any more information about the patient.

"Contra Costa Health Services is conducting a thorough investigation to identify anyone who may have had contact with the patient before they were isolated," Tzvieli said, reiterating that all hospitals in the county are safe for the public.

But Tzvieli warned that the case confirmed Tuesday may not be the only one.

"This case suggests coronavirus maybe circulating in Contra Costa County," he said,



Also on Tuesday, Santa Clara County reported two new cases of coronavirus and Berkeley reported its first case--it was a traveler who returned from Italy and had self-quarantined since returning.
