The latest case of the novel virus was announced Saturday night when a patient in Orange County, California, tested positive for the virus, which has caused worldwide alarm, according to the Centers for Disease Control and Prevention.
The patient, who was not identified, had recently returned to the United States after traveling in Wuhan, China, the epicenter of the illness, authorities said.
"The individual has now been transported to a local hospital and is in isolation in good condition," the Orange County Health Care Agency said in a statement.
Orange County officials are working with the CDC and the California Department of Public Health to reach people who have come in close contact with the patient and "are at risk of infection," according to the statement.
"There is no evidence that person-to-person transmission has occurred in Orange County. The current risk of local transmission remains low," the statement reads.
The California case comes after a man in his 30s hospitalized near Seattle was diagnosed with the coronavirus, and tests confirmed a woman in her 60s in Chicago had contracted the disease, officials said. Both patients had recently traveled to China.
Health authorities in Texas are investigating a suspected coronavirus case in a Texas A&M student, according to the local health department. The student, who recently traveled to Wuhan, went to an emergency department Wednesday with a cough and congestion.
