A Solano County resident has tested positive for the new coronavirus but had not recently traveled to any foreign country where the virus is spreading and had not had contact with any people with confirmed cases, public health officials said Wednesday.
The case marks the first time that U.S. authorities have not been able to determine the source of a coronavirus infection, and suggests that the virus may be spreading in the community. The patient is being treated in a Sacramento County hospital, according to the California Department of Public Health.
The Centers for Disease Control and Prevention announced the new case of COVID-19 Wednesday afternoon.
“At this time, the patient’s exposure is unknown,” the CDC said in a statement. “It’s possible this could be an instance of community spread of COVID-19, which would be the first time this has happened in the United States.”CDC spokesman Scott Pauley said the patient was identified “through the public health system,” but he could not say why the person was tested for coronavirus if he or she did not have recent travel in China or a known exposure to an individual with the virus.
It’s possible that the source of the infection will be determined with further interviews with the patient, the CDC said. Public health officials are now attempting to track where the person may have gone in the community and who he or she may have interacted with.
“We have been anticipating the potential for such a case in the U.S., and given our close familial, social and business relationships with China, it is not unexpected that the first case in the U.S. would be in California,” said Dr. Sonia Angell, director of the California Department of Public Health, in a statement.
The case is the 60th in the United States and the 28th in California.
The bulk of the infections have been in passengers who were evacuated from a cruise ship in Japan and moved to quarantine in the United States. Dozens of those passengers have been held at Travis Air Force Base in Fairfield, in Solano County, and 17 people have been transferred to Northern California hospitals for monitoring after testing positive for the virus.
Every other person who has tested positive so far had been on the cruise ship, had recently traveled to China, or had close interaction with someone who had recently traveled.
