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 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 U.S. Health Secretary Xavier Becerra.

Many other countries have lifted their testing requirements for fully vaccinated and boosted travelers in a bid to increase tourism.
