The United States has said all travellers two years and older must present negative test results before boarding a flight, regardless of vaccination status or citizenship. The US Centre for Disease Control in an updated travel advisory said the passengers’ test results should be taken no more than one day before travel, or documentation of having recovered from COVID-19 in the past 90 days, before they board their flight.
The regulation, updated on December 2, amended its October 25, 2021 Order, titled, ‘Requirement for Proof of Negative COVID-19 Test or Recovery from COVID-19 for All Air Passengers Arriving in the United States.’
