NATIONAL (Fox News): The Centers for Disease Control and Prevention (CDC) has reported the first case of person-to-person transmission of coronavirus in the U.S. In a telebriefing on Thursday, Dr. Robert Redfield, the CDC director, said the health agency had expected to identify “some” person-to-person spread in the U.S., but that risk to the American public “remains low.”

The case involves a Chicago resident, who is the spouse of the first confirmed travel-related case in Illinois. Officials stressed that the woman and her husband were in close contact before he developed symptoms. Both patients are in stable condition.

At this time, the CDC said it does not recommend the general public wear masks, but that those who have recently traveled to China be vigilant about reporting possible symptoms.

The virus, which originated in Wuhan, China, has sickened more than 7,700 people and has been linked to at least 170 deaths.
