As more is learned about the omicron variant, the Centers for Disease Control and Prevention is in the process of strengthening its protocols for international travel.
Currently the viral test can be done up to three days before departure for fully vaccinated passengers. But that’s set to change to one day before departure, to increase the likelihood of identifying a positive case.
The CDC continues to recommend travelers get a COVID test 3-5 days after arrival.
Already in place is a requirement that international travelers coming to the U.S. get a COVID-19 test before flying, and show a negative result to the airline.
