The Biden administration has renewed Covid-19 travel bans on non-US visitors from South Africa over its virus variant.
Brazil and most of Europe, including the UK and Ireland have also been included in the travel ban.
The new travel restrictions came as Minnesota recorded the first US case of the Brazil variant from a resident who had recently travelled to that country.
The US has so far recorded 25.3 million total cases of Covid-19, the highest in the world, and 421 000 deaths.
