Travellers from South America are no longer allowed to come into the UK, amid fears over a new coronavirus variant first identified in Brazil.
The UK s new travel ban - which also applies to Portugal and Cape Verde - came into force at 04:00 GMT on Friday.
Like variants discovered in the UK and South Africa, it is thought the Brazil variant could be more contagious.
Virologist Prof Wendy Barclay said one Brazilian variant had already been detected in the UK.
However, she said this was not the variant of concern , which is thought to be more infectious.
