The Department for Transport has announced that Portugal has been moved to the amber travel list as a result of concerns about coronavirus (COVID-19) variants and emerging mutations. This is the first update to the government’s traffic light list determining which countries are safe for international travel. Seven further countries (Afghanistan, Bahrain, Costa Rica, Egypt, Sri Lanka, Sudan, and Trinidad and Tobago) have moved from the amber list to the red list. The decision to move Portugal from green to amber came following the emergence of the so-called ‘Delta’ variant of the virus, 68 cases of which have been identified in Portugal. Public Health England is currently looking into the variant in an effort to understand its characteristics. The move means that those returning from Portugal will be required to book coronavirus travel tests for the second and eighth day from the date of return.
