The Biden administration is lifting its requirement that international travelers test negative for COVID-19 within a day before boarding a flight to the United States, ending one of the last remaining government mandates designed to contain the spread of the coronavirus.

The Centers for Disease Control and Prevention announced Friday that the requirement will end early Sunday morning. The health agency said it will continue to monitor the state of the pandemic and will reassess the need for a testing requirement if the situation changes.

“This step is possible because of the progress we’ve made in our fight against COVID-19,” said US Health Secretary Xavier Becerra.

Airline and tourism groups have been pressing the administration for months to eliminate the testing requirement, saying it discourages people from booking international trips because they could be stranded overseas if they contract the virus on their trip.

Airlines argued that the rule was put into effect when few Americans were vaccinated — now 71 percent of those 5 and older are fully vaccinated, according to CDC figures. They also complained that people entering the US at land borders are not required to test negative for COVID-19, although they must show proof of vaccination.
