Five cases of Wuhan coronavirus in the United States have been confirmed, the US Centers for Disease Control and Prevention said on Sunday.
In Arizona, one new case was confirmed, and two cases in California were confirmed. Cases had been confirmed previously in the state of Illinois and Washington. All of the cases were in people who had traveled to Wuhan, China recently.
The confirmed corona virus patient in Orange County, California, is in isolation at an area hospital in good condition, Dr. Nichole Quick, health officer for the Orange County Health Care Agency, told CNN on Sunday. The patient, a man in his 50s, recently returned from Wuhan through Los Angeles International Airport, though Quick would not confirm whether he returned before or after airport screenings began on January 17.
More cases are expected in the United States, but the risk to the general public is still considered low, Dr. Nancy Messonnier, director of the National Center for Immunization and Respiratory Diseases, said Sunday at a news briefing.
The C.D.C. is urging the public to get flu shots, to help reduce the number of people seeking treatment for symptoms that might be mistaken for the new coronavirus.
The agency is also preparing test kits to be sent to state health departments so that they can test for the virus instead of having to send samples to the C.D.C. for testing, but it will be a few more weeks before the kits are ready, Dr. Messonnier said.
