The ban, which also covers the Central American state of Panama and Portugal – due to its strong travel links with Brazil – and the former Portuguese colony of Cape Verde, came into force at 4am on Friday, January 15.
Scientists analysing the Brazilian variant believe the mutations it shares with the new South African strain seem to be associated with a rapid increase in cases in locations where there have already been large outbreaks of the disease.
Transport Secretary Grant Shapps described the ban as a “precautionary” move to ensure the vaccination programme rolling out across the UK was not disrupted by new variants of the virus.
“We don’t want to trip up at this late stage. We don’t have cases at the moment but this is a precautionary approach,” he told BBC News.
He also said there is an exemption for British and Irish nationals with residence rights, but that they must self-isolate for 10 days along with their households.
