Requiring a negative Covid-19 test to fly to the U.S. did not stop the Omnicron variant from entering the country, and it didn’t stop the Omicron wave. Requiring testing for travel but not for anything else makes no sense at all. The antigen tests that are accepted are hardly a guarantee against a passenger carrying the virus. We aren’t pursuing an ‘eradication’ policy against Covid like China is. Barely-piecemeal efforts are largely symbolic.
But the Biden administration says lifting the testing requirement for international travel is off the table.
