U.S. health authorities said Monday they are investigating 110 possible cases of the novel coronavirus across 26 states, but reported no new cases have been positively identified as the Trump administration urged Americans to reconsider all travel to China.

The Centers for Disease Control and Prevention said that total includes the five patients who have been tested possible for the disease, and 32 patients who have so far tested negative. Results for the remaining 73 patients remain pending, the agency said on its website.

The five confirmed cases include two patients in California, and one each in Washington state, Illinois, and Arizona. All of the patients had recently returned from China.

"While this is a serious public health threat, CDC continues to believe the immediate risk to the U.S. general public is low at this time," the CDC said in confirming the most recent cases in California and Arizona on Sunday.
