U.S. declares coronavirus a public health emergency

The Trump administration on Friday declared a public health emergency over the coronavirus outbreak and said it would bar entry to the United States starting on Sunday of foreign nationals who have traveled to China.

U.S. citizens who have traveled to China's Hubei Province within the last 14 days will be subject to a mandatory 14-day quarantine, Health and Human Services Secretary Alex Azar told a media briefing at the White House on Friday.

The administration will also limit flights from China to seven U.S. airports, he said.

He added that the risk to the U.S. public from the coronavirus outbreak is low.

Robert Redfield, director of the Centers for Disease Control and Prevention, said on Friday that there were 191 individuals in United States under investigation for the virus.
