Officials are still trying to find up to 480 people who flew from coronavirus-hit Wuhan to Britain and are still unaccounted for.
It comes as the UK government launched a huge advertising campaign telling people how to stop the spread of the killer virus.
Earlier 11 more British citizens arrived back in Britain after being flown out of Wuhan on a French plane.
The passengers – made up of British nationals and family members – will now be taken to Arrowe Park Hospital in the Wirral, where they will spend 14 days in quarantine.
They were evacuated from the city of Wuhan, which has been on lockdown since the outbreak.
They will be joining 83 UK nationals who are in quarantine close to Arrow Park Hospital on Merseyside.
China has now updated the death toll from the coronavirus outbreak to 361.
An additional 2,829 new cases have been reported over the last 24 hours, bringing the total number of known cases in China to 17,205.
The Sunday Times reported that UK government officials nine days ago began tracing 1,561 recent arrivals from Wuhan and that up to 480 remain unaccounted for.
Some of those people will remain within the incubation period of coronavirus, which can take between two and 14 days for symptoms to show.
The latest figures on Monday come a day after the first death from the illness was recorded outside China, in the Philippines, as countries around the world evacuated hundreds of their citizens from the infection zone.
Before the latest plane carrying Brit citizens set off, Foreign Secretary Dominic Raab said of the the latest evacuees: “They will go to the Arrowe Park facility and all of the protections, the support during the 14-day period, will be put in place.
“So they will be treated very well, and of course the reason we need to do that is on the one hand we want to get the UK nationals that want to leave China out, on the other hand we need to make sure we control and prevent the spread of the coronavirus because of the implications that that would have.”
The Government believe there may be around 30,000 British citizens in China.
“We’ll do everything we can to make sure that those that still want to leave, give them the opportunity to do so,” the Foreign Secretary added.
The latest repatriation comes as the Government launched a public health campaign advising people how to slow the spread of the virus.
The number of coronavirus tests that have come back negative in the UK is now 264, the Department of Health said.
Two patients tested positive for coronavirus on Friday, and are being treated in Newcastle.
