On 8 July 2020, the U.S. Embassy in Lisbon issued a Health Alert regarding U.S. travelers to Portugal, which reads in part as follows:

“All approved U.S. travelers to Portugal must present proof of a negative COVID-19 test conducted within 72 hours prior to boarding. Failure to do so may result in refusal to board, refusal of entry or mandatory testing at the cost of the passenger and quarantine upon arrival.
