On Christmas Eve, Outgoing US President announced that America would now require all air passengers arriving from the United Kingdom (U.K.) to test negative, via PCR or Antigen test, no more than 72 hours before departure from the U.K. to the United States.
The public health authorities in the United Kingdom recently announced the discovery of a new variant of SARS-CoV-2. Viruses constantly change through mutation, and preliminary analysis in the U.K. suggests that this new variant may be up to 70% more transmissible than previously circulating variants.
Under the new order, passengers are required to get a viral test (i.e., a test for current infection) within the 3 days before their flight from the U.K. to the U.S. departs, and provide written documentation of their laboratory test result (in hard copy or electronic) to the airline.
Airlines must confirm the negative test result for all passengers before they board. If a passenger chooses not to take a test, the airline must deny boarding to the passenger.
This order was signed on December 25, and becomes effective on December 28, 2020.
