The 63rd case of coronavirus reported Friday in Santa Clara County, California, is the second US case of unknown origin, according to the county’s public health department.
The individual diagnosed is an older adult woman with chronic health conditions who was hospitalized for a respiratory illness, the department said in a press release.
The woman’s infectious disease physician contacted the health department to discuss the case and request testing for coronavirus. Since receiving the results Thursday night, the department has been working to identify contacts and understand the extent of exposures, the release said.
“This new case indicates that there is evidence of community transmission, but the extent is still not clear,” said Dr. Sara Cody, the director of the county’s 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.”
