[NY Times] – Before boarding their flights, all international passengers headed to the United States will first need to show proof of a negative coronavirus test, according to a new federal policy going into effect on Jan. 26.
“Testing does not eliminate all risk,” Dr. Robert R. Redfield, the director of the Centers for Disease Control and Prevention, said in a statement describing the new policy.
“But when combined with a period of staying at home and everyday precautions like wearing masks and social distancing, it can make travel safer, healthier, and more responsible by reducing spread on planes, in airports, and at destinations.”
Dr. Redfield is expected to sign the order detailing the new rules on Tuesday.
The new policy requires all air passengers, regardless of vaccination status, to get a test for current infection within the three days before their flight to the United States departs, and to provide written documentation of their test results or proof of having recovered from Covid-19.
Proof of immunization will not be sufficient, because the vaccines have only been shown to prevent serious illness, said Jason McDonald, a spokesman for the C.D.C. Vaccinated people may still become infected, in theory, and transmit the virus on a flight.
The agency will not require further testing in the three months after a positive test, so long as the traveler has not had any symptoms. In this situation, a passenger may travel with documentation of the positive test result and a letter from a health care provider or a public health official stating that the traveler now has been cleared for travel.
Airlines must confirm the negative test result for all passengers or the documentation of recovery before they board. If a passenger does not provide proof of a negative test or recovery, or chooses not to take a test, the airline must deny boarding to the passenger, the agency said.
“Testing before and after travel is a critical layer to slow the introduction and spread of Covid-19,” agency officials said in a statement. “With the U.S. already in surge status, the testing requirement for air passengers will help slow the spread of the virus as we work to vaccinate the American public.”
The policy expands on a similar rule, implemented in late December, that required travelers from Britain to show proof of a negative result on a test for the virus. The Trump administration introduced that restriction following reports that a more contagious variant of the coronavirus had become the source of the majority of infections in much of that country.
