Her doctor contacted the public health department and requested testing for COVID-19. The county's laboratory received specimens on Thursday and performed testing, which later came back positive for the coronavirus.
"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.”
This latest patient is the third COVID-19 case in Santa Clara County, but different from the other two cases previously diagnosed since the patient has no travel history or known exposure to the virus.
