LOS ANGELES (AP) — The U.S. has five confirmed cases of the new virus from China, all among people who traveled to the city at 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 latter case was someone with ties to Arizona State University who did not live in school housing and had a history of travel to Wuhan, China, state health officials said.

Officials with the Arizona Department of Health Services said the Maricopa County patient wasn’t severely ill and was in isolation at home to keep the illness from spreading. The department said it would not release potentially identifying information on the person, including the gender and age, and declined to say whether the person was a student or faculty member. The LA patient alerted authorities that he wasn’t feeling well upon arriving at Los Angeles International Airport. The patient was taken by ambulance to a hospital, health officials said at a Sunday news conference.

“Everything worked as it should,” said Dr. Sharon Balter with the LA County Department of Public Health. “The patient presented for care, the patient was immediately transported to a hospital, the patient has remained in the hospital.”
