The U.S. has five confirmed cases of the new virus from China, all of whom traveled to the city that is the center of the outbreak, health officials said Sunday. Two new cases were reported Sunday — one in Los Angeles County in California and the other in Maricopa County, Arizona. The Arizona person is a student at Arizona State University who recently returned from Wuhan, China. The Arizona Department of Health says the student is not severely ill but is being kept in isolation to prevent the virus from spreading. The student does not reside in university housing.
