The UK’s chief medical officers today raised the risk of the killer coronavirus to high and admitted up to 10,000 people in Britain could already be infected.  

Prime Minister Boris Johnson declared the outbreak as the ‘worst public health crisis for a generation’, after the UK recorded its biggest daily jump in cases.

Ten patients have already died and almost 600 have been infected – the escalating outbreak is now 40 times bigger than it was a fortnight ago.  

The PM formally declared the UK’s tactics have shifted from ‘containing’ to ‘delaying’ its inevitable spread after chairing a meeting of the Cobra emergency committee.

In a frank admission at the same conference, Number 10’s chief scientific adviser revealed the true number of cases in Britain was ‘likely’ between 5,000 and 10,000. 

However, officials stressed that the ‘most dangerous period’ of the outbreak is some weeks away, depending on how rapidly it spreads. 

Official advice to contain the crisis has now been ramped up, with anyone who has a cough or temperature told to self-isolate at home for a week.

And England’s chief medical officer said ‘the great majority’ are not infectious after seven days, claiming it is ‘fine’ for them to go back into society. 

The chief medical officer for England, Professor Chris Whitty, said the risk rating from coronavirus had been raised to high, in agreement with counterparts in Scotland, Wales and Northern Ireland. He is pictured speaking at a 10 Downing Street conference 

Government chief scientific adviser, Sir Patrick Vallance, said: ‘We are in a period now where we’ve got some [cases] but it hasn’t yet taken off’. He explained the Government’s actions were to try and delay the peak of coronavirus in the UK towards the summer, when the NHS are more likely to cope with the pressure

How the UK’s coronavirus ‘battle plan’ could unfold


Testing individuals reporting symptoms or returning from infected areas, isolating those who have coronavirus.

Tracing how they contracted the virus, and everyone they might have come into contact with while infectious.

Powers have been taken to force people into quarantine if they refuse to comply voluntarily. 


Ministers have ordered wider testing to assess prevalence in the community. 

Anyone with coronavirus-like symptoms are being asked to self-isolate, and vulnerable people urged to stay indoors.

Sick pay provision has been bolstered to make the self-employed and low-paid workers more likely to comply. 

Further up the so-called ‘ladder’ of response options, schools could be closed, and sports and public gatherings banned. 

Ministers say the scientific advice advice does not yet support that – although Ireland is closing schools, and Scottish First Minister Nicola Sturgeon is banning gatherings of more than 500 people.

The government has also rejected the US approach of barring travellers from mainland Europe for the moment. 


If the outbreak runs out of control, the NHS could cancel all non-urgent activity to focus on treating those affected.

In an extreme situation, troops could be deployed to shore up the police and essential public services.

Recently-retired doctors and nurses would be brought back to help plug gaps in the NHS, with many health workers expected to be infected along with regular members of the public. 

The chief medical officer for England, Professor Chris Whitty, said the risk rating from coronavirus had been raised to high, in agreement with counterparts in Scotland, Wales and Northern Ireland. 

The risk level was bumped from low to moderate on January 30, when two cases had been confirmed in the UK and cases were still soaring in China.  

According to Public Health England (PHE), a change in risk level does not mean the threat to individuals in the UK has changed, but that the government should plan for all eventualities.

In the same meeting today, the PM set out measures that could ’cause severe disruption for many months’.

He said anyone with coronavirus symptoms, however mild, such as a cough or high temperature, must now stay at home for seven days.

They will not be tested for coronavirus, Professor Whitty said, as the NHS shifts its approach to prioritising those in hospitals.

‘It is no longer necessary for us to identify every case,’ Professor Whitty said.

‘We will pivot all the testing capacity to identify those in hospitals who have symptoms so we can pick them up early, make sure we treat them well and ensure they don’t pass on the virus to other people in hospitals. ‘  

Mr Johnson added school trips abroad should be stopped, while people over 70 with serious medical conditions should not go on cruises.

But Mr Johnson said there was no need to close schools now as the scientific advice ‘is that this could do more harm than good’.

He said this tactic may change at some point, while in the future anybody living with somebody who is taken ill will also be told to self-isolate for seven days.

Mr Johnson said families would continue to ‘lose loved ones before their time’ as the coronavirus outbreak worsens.

‘We’ve all got to be clear, this is the worst public health crisis for a generation,’ said the PM.

‘Some people compare it to seasonal flu, alas that is not right. Due to the lack of immunity this disease is more dangerous.

‘It is going to spread further and I must level with you, I must level with the British public: many more families are going to lose loved ones before their time.’

Mr Johnson said the Government was ‘considering the question of banning major sporting events’.

He said the evidence suggests it will ‘have little effect on the spread’ of coronavirus, though such events did place a burden on public services. 

Sir Patrick Vallance, the chief scientific adviser, said the UK was likely to have between 5,000 and 10,000 coronavirus cases, but admitted the worst is yet to come.

He said: ‘Currently we are on a trajectory that looks as though it is about four weeks or so behind Italy and some other countries in Europe. 

‘There are currently 590 cases that have been identified in the UK and there are more than 20 patients in intensive care units. 

‘If you calculate what that really means in terms of the total number, it is much more likely that we have between 5,000 and 10,000 people infected at the moment. That is still a relatively small number.’

Sir Vallance said the timing of interventions is ‘critical’, but drastic measures are not needed at the moment because the number of cases is ‘small’. 

He said: ‘What you want to do is to protect people during the most infectious period. We are in a period now where we’ve got some [cases] but it hasn’t yet taken off.

‘During the period of peak transmission, we need to protect [the vulnerable and elderly] at the stage. If you do that at the moment, you’re not protecting anybody because the cases are so small. 

‘If you do it at the right time then you are protecting them over the peak and you’re not asking them to be in isolation for too long.’

Sir Vallance explained that schools hadn’t been closed because the effect would be ‘minimal’ at this stage, and could potentially lead to children being cared for by their grandparents – who are at risk of infection.

He said: ‘Schools its true there are some effect in closing schools but that effect is minimal, and actually you’d have to do it for 13 to 16 weeks or longer and you don’t need to be an advanced mathematician to work out that the chances of keeping children speaking or playing with each over 13 to 16 weeks is zero.

‘And therefore you have to very careful to take the right measures to stop this rather than things that might end up with children for example going to stay with grandparents at a time they are most vulnerable.’ 

Mr Johnson said in a statment: ‘We have to deploy these at the right time to maximise their effect. 

‘The most important task will be to protect our elderly and most vulnerable people during the peak weeks when there is the maximum risk of exposure to the disease and when the NHS will be under the most pressure. 

‘So the most dangerous period is not now but some weeks away depending on how fast it spreads.’

Public Health England confirmed the new stay-at-home guidance for those with confirmed or suspected cases of coronavirus.

The advice states not to go to work, school, or public areas, use public transport or taxis or even go for a walk.

In the guidance, those with even mild symptoms of infection are also urged to stay at least two metres away from other people in their homes whenever possible and to sleep alone.

Where possible, those with confirmed or suspected cases should use a separate bathroom from the rest of the household.

For infected people with shared toilets and bathrooms, the Government advice says to clean them after every use.

The recommended period of self-isolation has also reduced from 14 days to one week, as most people will no longer be likely to transmit the virus a week after the onset of symptoms.


Someone who is infected with the coronavirus can spread it with just a simple cough or a sneeze, scientists say.

More than 4,500 people with the virus are now confirmed to have died and more than 125,000 have been infected. Here’s what we know so far:

What is the coronavirus? 

A coronavirus is a type of virus which can cause illness in animals and people. Viruses break into cells inside their host and use them to reproduce itself and disrupt the body’s normal functions. Coronaviruses are named after the Latin word ‘corona’, which means crown, because they are encased by a spiked shell which resembles a royal crown.

The coronavirus from Wuhan is one which has never been seen before this outbreak. It has been named SARS-CoV-2 by the International Committee on Taxonomy of Viruses. The name stands for Severe Acute Respiratory Syndrome coronavirus 2.

Experts say the bug, which has killed around one in 50 patients since the outbreak began in December, is a ‘sister’ of the SARS illness which hit China in 2002, so has been named after it.

The disease that the virus causes has been named COVID-19, which stands for coronavirus disease 2019.

Dr Helena Maier, from the Pirbright Institute, said: ‘Coronaviruses are a family of viruses that infect a wide range of different species including humans, cattle, pigs, chickens, dogs, cats and wild animals. 

‘Until this new coronavirus was identified, there were only six different coronaviruses known to infect humans. Four of these cause a mild common cold-type illness, but since 2002 there has been the emergence of two new coronaviruses that can infect humans and result in more severe disease (Severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) coronaviruses). 

‘Coronaviruses are known to be able to occasionally jump from one species to another and that is what happened in the case of SARS, MERS and the new coronavirus. The animal origin of the new coronavirus is not yet known.’ 

The first human cases were publicly reported from the Chinese city of Wuhan, where approximately 11million people live, after medics first started publicly reporting infections on December 31.

By January 8, 59 suspected cases had been reported and seven people were in critical condition. Tests were developed for the new virus and recorded cases started to surge.

The first person died that week and, by January 16, two were dead and 41 cases were confirmed. The next day, scientists predicted that 1,700 people had become infected, possibly up to 7,000.

Just a week after that, there had been more than 800 confirmed cases and those same scientists estimated that some 4,000 – possibly 9,700 – were infected in Wuhan alone. By that point, 26 people had died. 

By January 27, more than 2,800 people were confirmed to have been infected, 81 had died, and estimates of the total number of cases ranged from 100,000 to 350,000 in Wuhan alone.

By January 29, the number of deaths had risen to 132 and cases were in excess of 6,000.  

By February 5, there were more than 24,000 cases and 492 deaths.

By February 11, this had risen to more than 43,000 cases and 1,000 deaths. 

A change in the way cases are confirmed on February 13 – doctors decided to start using lung scans as a formal diagnosis, as well as laboratory tests – caused a spike in the number of cases, to more than 60,000 and to 1,369 deaths.

By February 25, around 80,000 people had been infected and some 2,700 had died. February 25 was the first day in the outbreak when fewer cases were diagnosed within China than in the rest of the world. 

Where does the virus come from?

According to scientists, the virus almost certainly came from bats. Coronaviruses in general tend to originate in animals – the similar SARS and MERS viruses are believed to have originated in civet cats and camels, respectively.

The first cases of COVID-19 came from people visiting or working in a live animal market in Wuhan, which has since been closed down for investigation.

Although the market is officially a seafood market, other dead and living animals were being sold there, including wolf cubs, salamanders, snakes, peacocks, porcupines and camel meat. 

A study by the Wuhan Institute of Virology, published in February 2020 in the scientific journal Nature, found that the genetic make-up virus samples found in patients in China is 96 per cent identical to a coronavirus they found in bats.

However, there were not many bats at the market so scientists say it was likely there was an animal which acted as a middle-man, contracting it from a bat before then transmitting it to a human. It has not yet been confirmed what type of animal this was.

Dr Michael Skinner, a virologist at Imperial College London, was not involved with the research but said: ‘The discovery definitely places the origin of nCoV in bats in China.

‘We still do not know whether another species served as an intermediate host to amplify the virus, and possibly even to bring it to the market, nor what species that host might have been.’  

So far the fatalities are quite low. Why are health experts so worried about it? 

Experts say the international community is concerned about the virus because so little is known about it and it appears to be spreading quickly.

It is similar to SARS, which infected 8,000 people and killed nearly 800 in an outbreak in Asia in 2003, in that it is a type of coronavirus which infects humans’ lungs. It is less deadly than SARS, however, which killed around one in 10 people, compared to approximately one in 50 for COVID-19.

Another reason for concern is that nobody has any immunity to the virus because they’ve never encountered it before. This means it may be able to cause more damage than viruses we come across often, like the flu or common cold.

Speaking at a briefing in January, Oxford University professor, Dr Peter Horby, said: ‘Novel viruses can spread much faster through the population than viruses which circulate all the time because we have no immunity to them.

‘Most seasonal flu viruses have a case fatality rate of less than one in 1,000 people. Here we’re talking about a virus where we don’t understand fully the severity spectrum but it’s possible the case fatality rate could be as high as two per cent.’

If the death rate is truly two per cent, that means two out of every 100 patients who get it will die. 

‘My feeling is it’s lower,’ Dr Horby added. ‘We’re probably missing this iceberg of milder cases. But that’s the current circumstance we’re in.

‘Two per cent case fatality rate is comparable to the Spanish Flu pandemic in 1918 so it is a significant concern globally.’

How does the virus spread?

The illness can spread between people just through coughs and sneezes, making it an extremely contagious infection. And it may also spread even before someone has symptoms.

It is believed to travel in the saliva and even through water in the eyes, therefore close contact, kissing, and sharing cutlery or utensils are all risky. It can also live on surfaces, such as plastic and steel, for up to 72 hours, meaning people can catch it by touching contaminated surfaces.

Originally, people were thought to be catching it from a live animal market in Wuhan city. But cases soon began to emerge in people who had never been there, which forced medics to realise it was spreading from person to person. 

What does the virus do to you? What are the symptoms?

Once someone has caught the COVID-19 virus it may take between two and 14 days, or even longer, for them to show any symptoms – but they may still be contagious during this time.

If and when they do become ill, typical signs include a runny nose, a cough, sore throat and a fever (high temperature). The vast majority of patients will recover from these without any issues, and many will need no medical help at all.

In a small group of patients, who seem mainly to be the elderly or those with long-term illnesses, it can lead to pneumonia. Pneumonia is an infection in which the insides of the lungs swell up and fill with fluid. It makes it increasingly difficult to breathe and, if left untreated, can be fatal and suffocate people.

Figures are showing that young children do not seem to be particularly badly affected by the virus, which they say is peculiar considering their susceptibility to flu, but it is not clear why. 

What have genetic tests revealed about the virus? 

Scientists in China have recorded the genetic sequences of around 19 strains of the virus and released them to experts working around the world. 

This allows others to study them, develop tests and potentially look into treating the illness they cause.   

Examinations have revealed the coronavirus did not change much – changing is known as mutating – much during the early stages of its spread.

However, the director-general of China’s Center for Disease Control and Prevention, Gao Fu, said the virus was mutating and adapting as it spread through people.

This means efforts to study the virus and to potentially control it may be made extra difficult because the virus might look different every time scientists analyse it.   

More study may be able to reveal whether the virus first infected a small number of people then change and spread from them, or whether there were various versions of the virus coming from animals which have developed separately.

How dangerous is the virus?  

The virus has a death rate of around two per cent. This is a similar death rate to the Spanish Flu outbreak which, in 1918, went on to kill around 50million people.

Experts have been conflicted since the beginning of the outbreak about whether the true number of people who are infected is significantly higher than the official numbers of recorded cases. Some people are expected to have such mild symptoms that they never even realise they are ill unless they’re tested, so only the more serious cases get discovered, making the death toll seem higher than it really is.

However, an investigation into government surveillance in China said it had found no reason to believe this was true.

Dr Bruce Aylward, a World Health Organization official who went on a mission to China, said there was no evidence that figures were only showing the tip of the iceberg, and said recording appeared to be accurate, Stat News reported.

Can the virus be cured? 

The COVID-19 virus cannot be cured and it is proving difficult to contain.

Antibiotics do not work against viruses, so they are out of the question. Antiviral drugs can work, but the process of understanding a virus then developing and producing drugs to treat it would take years and huge amounts of money.

No vaccine exists for the coronavirus yet and it’s not likely one will be developed in time to be of any use in this outbreak, for similar reasons to the above.

The National Institutes of Health in the US, and Baylor University in Waco, Texas, say they are working on a vaccine based on what they know about coronaviruses in general, using information from the SARS outbreak. But this may take a year or more to develop, according to Pharmaceutical Technology.

Currently, governments and health authorities are working to contain the virus and to care for patients who are sick and stop them infecting other people.

People who catch the illness are being quarantined in hospitals, where their symptoms can be treated and they will be away from the uninfected public.

And airports around the world are putting in place screening measures such as having doctors on-site, taking people’s temperatures to check for fevers and using thermal screening to spot those who might be ill (infection causes a raised temperature).

However, it can take weeks for symptoms to appear, so there is only a small likelihood that patients will be spotted up in an airport.

Is this outbreak an epidemic or a pandemic?   

The outbreak was declared a pandemic on March 11. A pandemic is defined by the World Health Organization as the ‘worldwide spread of a new disease’. 

Previously, the UN agency said most cases outside of Hubei had been ‘spillover’ from the epicentre, so the disease wasn’t actually spreading actively around the world.
