The United States will begin requiring people flying in from the UK to test negative for Covid-19 no more than 72 hours before departure, the CDC said in a late Thursday statement.
The CDC said passengers should provide airlines with documentation of their laboratory results from either polymerase chain reaction (PCR) and antigen tests.
Airlines will also need to confirm that passengers have tested negative before boarding, the agency said. They will also have to block passengers from boarding if they refuse to take a test.
The CDC said President Donald Trump will sign the order Friday, Christmas Day. It will take effect from Monday.
Earlier this week, the UK said it identified one new strain of Covid-19 which seems to be spreading faster. Dozens countries quickly restricted travel from the UK in an effort to prevent the load from entering their own limits.
The United States had already done so limited travel from the UK in March and excluded foreigners who had been in the country for the past two weeks.
