The patients are:
An older woman in northern California with chronic health conditions
A high school student in Everett, Washington
An employee at an elementary school in Portland, Oregon
None of the patients had recently travelled overseas or had any known close contact with a traveller or an infected person, authorities said.
Santa Clara County in the San Francisco Bay Area also reported two cases where the source of infection wasn’t known, AP reported.
The new coronavirus cases of unknown origin marks an escalation of the worldwide outbreak in the U.S. because it means the virus could spread beyond the reach of preventative measures like quarantines, though state health officials said that was inevitable and that the risk of widespread transmission remains low.
California public health officials on Friday said more than 9,380 people are self-monitoring after arriving on commercial flights from China through Los Angeles and San Francisco. That’s up from the 8,400 that Gov. Gavin Newsom cited on Thursday, though officials said the number increases daily as more flights arrive.
Officials are not too worried, for now, about casual contact, because federal officials think the coronavirus is spread only through “close contact, being within six feet of somebody for what they’re calling a prolonged period of time,” said Dr. James Watt, interim state epidemiologist at the California Department of Public Health.

The US has barely tested anyone. They have nearly 10,000 people who are 'self monitoring' in California alone which is completely meaningless in a country with little sick pay protection, workers rights nor health cover. Self monitoring is also a level down from the 'self-isolating' advice we are getting in the UK (which being uncontrolled and not monitored is bad enough with our social security provisions)
At least we only have a lazy arse who refuses to work weekends rather than one who propogates conspiracy theories over a public health emergency.
