The Biden administration's new, stricter Covid-19 testing requirements for all travelers coming to the United States will take effect on Monday, an administration official told CNN.
The new rules will require each traveler flying into the US from another country to test negative one day before their departure, changing rules that had allowed inbound travelers to test up to three days before entering the country. The new rule from the US Centers for Disease Control and Prevention will take effect at 12:01 a.m. ET on Monday.
The shift in policy -- which President Joe Biden announced Thursday alongside a slate of new steps to combat Covid-19 this winter -- underscores the potential threat posed by the newly discovered Omicron variant. Scientists are still working to determine how transmissible the variant is, how sick it makes people and how well the current vaccines work against it.
