The
United States has taken decisive action to protect Americans from the threat of a fast-moving coronavirus while offering help to China, President
Donald Trump said on Sunday, but a key adviser said
Beijing had not accepted the offers of assistance.
Concerns about the virus spurred the United States to declare a public health emergency and bar entry to foreign nationals who have recently visited China.
Under new restrictions that go into effect at 5 p.m. ET (2200 GMT) Sunday, U.S. citizens who have traveled in
China within 14 days will be directed to one of seven airports designated for screening.
