The UK has today imposed more travel bans following the discovery of a new mutant strain of Covid-19 - so what countries are now affected?
Transport Secretary Grant Shapps announced travel from 15 South American countries, as well as Portugal - singled out because of its "strong travel links" with Brazil.
It joins large swathes of Southern Africa, which was hit by similar bans after another highly-transmissible variant was identified in South Africa.
On December 23, Health Secretary Matt Hancock said two cases of the South African strain had been found in the UK, but it is not yet known if the Brazilian variant has made it to these shores.
