A second coronavirus case of unknown origin has been confirmed in the United States, health officials in the San Francisco Bay Area announced Friday.

The case in Santa Clara County comes after authorities two days earlier said a woman in Solano County may have been the first case in the country to contract the virus through exposure in the community. Both incidents have placed Northern California as the epicenter of what officials are calling the turning point in the spread of the highly contagious coronavirus.

After the second coronavirus case of unknown origin is confirmed in Santa Clara County, officials say now is the time to prepare. Ian Cull and Sergio Quintana report.

“This new case indicates that there is evidence of community transmission but the extent is still not clear,” said Dr. Sara Cody, Health Officer for Santa Clara County and Director of the County of Santa Clara Public Health Department. “I understand this may be concerning to hear, but this is what we have been preparing for. Now we need to start taking additional actions to slow down the spread of the disease.”

The new case is the third confirmed case of coronavirus in Santa Clara County. The woman in this latest confirmed case did not travel to any coronavirus-affected areas or knowingly come into contact with an infected person, officials said.

Authorities said the new confirmed case in Santa Clara County also is not tied to the Diamond Princess cruise ship, which was docked in Japan with passengers quarantined. Passengers were evacuated, with dozens transported earlier this month to Travis Air Force Base in Fairfield for coronavirus quarantine.
