With the two new California cases, the number of Americans with coronavirus has risen to five. Both individuals recently traveled from Wuhan, China, where the virus originated. They have both been transported to hospitals.
The Orange County individual is in good condition, according to a press release.
The virus, known as nCoV, is a new strain that hasn't been previously identified in humans.
The Department of State will be relocating American diplomats and citizens living in Wuhan on a flight to San Francisco on Jan. 28.
The press release did not specify the airport the evacuated individuals will be arriving at.
Spokespersons from the San Francisco, San Jose and Oakland International Airport said there were no plans, thus far, for the evacuated individuals to land at their locations.
The Centers for Disease Control say symptoms of coronavirus include fever, coughing and shortness of breath. Symptoms can appear in as little as 2 days or as long as 14 days after exposure.
The three other U.S. cases of coronavirus have been reported in Washington State and Chicago. On Sunday afternoon, Maricopa County in Arizona reported a case.
As of Sunday, there have been 1,975 confirmed cases of the virus in China, with 56 deaths. Thailand, Japan and South Korea have also reported cases.
