From Monday midnight, everyone traveling from the US will be required to test for coronavirus within three days of entry, according to CNN.
Previously, travelers coming from the US were required to self-isolate, but only test for coronavirus if symptomatic.
Jung stated that the measure was taken because "as the ratio of positive cases among those entering from the US continues to rise, and the risk of community spread in the US continues to rise, we deem that the risk of infection of travelers from the US has risen".
