Travellers from China who test positive for Covid will not have to self-isolate

Travellers from China will not be forced to take Covid tests on arrival or self-isolate even if they take them and are positive, Government bosses have confirmed.

No10 is bringing back travel restrictions for passengers from the country — apart from Hong Kong — on Thursday, amid a surge of cases that is blighting the nation.

These include having to present a negative test before boarding a flight to London Heathrow or Manchester, the two airports Chinese flights arrive at.

But PCR tests that are used to track new variants — like the ‘Kraken’ XBB.1.5 strain — and are available on arrival will not be made compulsory, the Department of Health and Social Care revealed.

A DHSC spokesperson said: ‘We encourage people at the border to take a test to help themselves, their families and wider knowledge on Covid.

‘However the testing is optional and people can decline if they wish to do so.’

And, in stark contrast to other countries, passengers who do take a swab and test positive will not have to self-isolate, the Transport Secretary admitted today. 

Asked they would be required to quarantine, Mark Harper told LBC: ‘No, because what we are doing is we are collecting that information for surveillance purposes.

‘But, look, one in 45 people in the United Kingdom have got Covid at the moment.’

The new travel restrictions were brought in on New Year’s Eve because of fears China’s outbreak could introduce a dangerous new variant in the UK.

Other countries, including the US, Canada, Italy, Spain and France, all brought in similar measures to deal with the ‘key threat’ of killer strains.

Covid is currently overwhelming hospitals in China, after cases ballooned in the country when Beijing’s controversial ‘zero Covid’ policy was lifted in December. 

Experts believe low vaccination levels combined with weak natural immunity caused by delaying lifting the policy is behind the sudden rise.

But they also fear the latest wave — which is thought to be seeing more cases than ever in the country — could spawn the perfect breeding ground for a new variant. 

China has also been accused of under-reporting its cases and withholding virus samples, reducing the likelihood of any new variant being spotted.

XBB.1.5 has already caused alarm in the US over its quick spread and a recent rise in hospitalisations. It is behind four in ten cases in the country, up from two a week ago.

The variant, which is a version of Omicron, has mutations that help it dodge protection from vaccination and prior infections. 

Experts yesterday told MailOnline that strain is a ‘wakeup call’ and could worsen NHS crisis, which has seen the health service battered by a ‘twindemic’ of Covid and flu.

The pressure on the NHS — thought to be higher than during the peak of the pandemic — has already led to new Government advice to wear a face mask if you feel unwell.

The Our World in Data graph shows the daily confirmed Covid cases in China. The Chinese Center for Disease Control and Prevention last week stopped reporting daily cases, without providing a reason. It reported around 5,000 cases per day last week and a small number of deaths. However, some estimates suggest China is actually experiencing one million cases per day and 5,000 deaths

Figures from the Sanger Institute, one of the UK’s largest Covid surveillance centres, shows 4 per cent of cases in the week to December 17 were caused by XBB.1.5 (shown in purple, bottom right corner)

Meanwhile, sequencing data suggests that a different Omicron sub-variant — BF.7 — is on the rise in China, causing 35.3 per cent of positive cases that have been studied in laboratories. 

Beijing is planning to ease its own international travel restrictions on January 8, allowing more citizens to go to the UK and other countries.

Ministers have said they plan to test a ‘sample’ of passengers on arrival to check for variants.

But people coming from the country will be allowed to simply decline a test if they choose, raising the risk they could be positive and go undetected. 

This contrasts to countries like Japan, which tests all passengers that have been in mainland China in the last seven days and quarantines them if they test positive.

Asked about the UK’s policy, Mr Harper said: ‘We manage Covid now by making sure we have got very high levels of vaccination, that is why people who are at risk, older members of the community for example, should make sure they get their fourth booster shot this winter.

‘That is how we protect people from Covid, that is our primary line of defence.

‘The policy for arrivals from China is primarily about collecting information that the Chinese government are not sharing with the international community.’

Mr Harper said the UK Government has created a ‘sensible, balanced proposition’ to deal with the potential spread of Covid from China.

He said: ‘This is about a country, China, which isn’t sharing the health data with the global health system that we expect everybody to do.

‘That is why we have put this temporary precautionary measure in place as China opens up its borders.

‘We are doing two things — we are requiring people who fly from China to have a pre-departure test so they have got to show that they are negative before they get on that flight, and when they get to the United Kingdom the UK Health Security Agency will take a sample of passengers and test them.

‘That is so that we get that information into our health system and we can track the virus that is coming from China.

‘That, I think, is a very sensible, balanced proposition which I think helps keep people in the UK safe but doesn’t put any restrictions on how people in the UK are able to operate.’

Mr Harper also said wearing a mask is ‘sensible’ if people need to go out while ill.

Asked if he would wear a mask if he was ill with coronavirus, he told LBC: ‘First of all you should stay at home if you think you have got Covid or you have got flu — actually the most sensible thing to do is to not go out and spread it.

‘If you do go out, clearly wearing a mask is very sensible if you are ill. But we manage these illnesses now by vaccination.

‘People should get vaccinated for Covid, they should also get a flu vaccination. We have seen very high levels of flu this winter.’

What do we know about XBB.1.5? 

A highly contagious Covid strain has emerged and is already behind one in 25 cases in the UK, data suggests

What is XBB.1.5?

XBB.1.5 is a new Covid variant that is sparking concerns across the world.

The strain is a mutated version of Omicron XBB, which was first detected in India in August. 

XBB, which is a merger of variants BJ.1 and BA.2.75, caused cases to quadruple in just one month in some nations.

XBB.1.5 has gained additional mutations, including F486P, which help it to bypass Covid-fighting antibodies that were generated in response to vaccination or previous infection.

Another change — S486P — is thought to improve its ability to bind to cells.

Where has it been spotted?

Concern about XBB.1.5 is largely based on how it is currently sweeping the US — but it has also already been spotted in Britain and other countries around the globe.

Data from the US Centers for Disease Control and Prevention (CDC) on Friday showed that the strain is behind 41 per cent of cases. The figure is up from 22 per cent one week earlier.

Figures from the Sanger Institute, one of the UK’s largest Covid surveillance centres, shows four per cent of cases in the week to December 17 were caused by XBB.1.5.

It is the first time the strain has been listed on the institute’s virus dashboard, which is updated weekly.

XBB.1.5 has also been spotted in countries including France, Germany, the Netherlands, Spain, Ireland, Australia, Singapore and India.

Is the variant concerning?

Experts are concerned XBB.1.5’s rapid rise in the US could be caused by mutations that help it to better infect people and dodge protection from vaccination and prior infections.

Professor Lawrence Young, a virologist at Warwick University, told MailOnline that the emergence of the strain is a ‘wakeup call’ and could exacerbate the NHS crisis in Britain.

Professor Paul Hunter, an epidemiologist at the University of East Anglia, told MailOnline that the majority of new variants ‘fizzle out in a few weeks’.

However, the sharp increase in XBB.1.5’s prevalence is ‘certainly very worrying’ and suggests ‘a pretty dramatic growth advantage and enough to drive a new wave of infections’, he said.

Why are some scientists not worried?

Not all experts are so concerned, however. 

Dr Simon Clarke, a microbiologist based at the University of Reading, told MailOnline that while XBB.1.5’s ability to evade immunity has only been observed in the lab.

‘So it’s difficult to know how this will translate into real life,’ he noted.

While hospitalisations in the US are rising in many regions, ‘the presence of this variant doesn’t seem to be responsible for that’, Dr Clarke said.

Also, it doesn’t seem to be causing more serious disease than other circulating variants, which are the most important metrics to watch when tracking Covid, he said.

Dr Clarke added: ‘It will be interesting to see how the situation develops over the coming months as the usual annual wave of flu hospitalisations is usuallyhighest in January and February.’

Professor Francois Balloux, an infectious disease expert based at University College London, told MailOnline that XBB.1.5 cases ‘will likely go up in frequency globally’ in the near future. 

He added: ‘As such, it would contribute to push case numbers higher over the coming weeks. That said, it is far from clear XBB.1.5 will cause a massive wave on its own.’
