The UK will add four more countries to its red list after two cases of the Omicron coronaviruses variant were found there.
The travel red list will be expanded from 4am on Sunday after fresh advice from the UK Health Security Agency.
The travellers who have returned from these countries in the last 10 days must get a test.
The UKHSA is following up on recent arrivals from these countries. The red list may include more countries.
Sajid Javid, the health secretary, said: "We will do all we can to protect the UK public against this emerging threat and that is why we are introducing travel restrictions on a further four countries." If necessary, we will take further action.
Non-UK and non-Irish residents who have been in several African countries in the last 10 days will not be allowed into England on Sunday. Those who have stayed airside and only transited through any of these countries while changing flights will not be affected.
UK and Irish residents must stay in a government-approved facility for 10 days after arriving on Sunday. They will have to take a test on day two and day eight.
Passengers arriving in the UK from countries like South Africa, Lesotho, Eswatini and Zimbabwe will be required to book and pay for a government-approved hotel from 4am on Sunday.
