In one of the most anticipated travel developments this year, the US Centers for Disease Control and Prevention is poised to lift its requirement for travelers to test negative for Covid-19 before entering the United States, CNN learned on Friday.
The measure has been in place since January 2021. The move is likely to encourage travelers around the world to plan a summer vacation in the States and encourage more US travelers to venture abroad knowing they're less likely to get stranded overseas with a positive test. Air travel has been far from smooth this season so far.
Japan also finally opened its borders to international tour groups on June 10, although individual travelers are not yet permitted to enter.
