Thailand admits it is ‘unable to stop the spread’ of China’s deadly coronavirus as health minister warns more cases are coming
- Health minister Anutin Charnvirakul said there are too many Chinese visitors
- At least 22,000 people from Wuhan are believed to have visited in January
- Thailand, with 14 cases, is so far the worst affected country outside of China
Thailand is ‘not able to stop the spread’ of the deadly Wuhan coronavirus which has been imported from China, according to a health minister in the country.
With 14 confirmed cases of the disease, Thailand is the worst-affected nation outside of China.
And it became the first one to confirm overseas cases on January 13, before Japan followed suit on January 16.
But health minister Anutin Charnvirakul has reportedly admitted the country cannot stop the virus from spreading because there are so many Chinese travellers there.
Almost 4,600 people have caught the Wuhan coronavirus around the world so far, and 106 have died in China.
Thai health minister Anutin Charnvirakul told Sky News: ‘We are not able to stop the spread… Of course we expect more people to get sick’
‘We are not able to stop the spread,’ Mr Charnvirakul told Sky News.
‘Our target is we will be able to detect all carriers entering Thailand and we will apply necessary measures as the situation develops.
‘Of course we expect more people to get sick but we are able to identify all of them.’
The Wuhan coronavirus has now been infecting people in China and abroad for four weeks since it was first noticed on December 31.

WHERE HAS THE WUHAN CORONAVIRUS SPREAD TO?
The vast majority of confirmed infections of the Wuhan coronavirus (4,515 out of 4,585, as at 11.40am GMT on January 28) have been diagnosed in China.
But 17 countries or territories outside of the mainland have also declared infections:
- Germany: One case confirmed, diagnosed January 27
- Sri Lanka: One case, diagnosed January 27
- Cambodia: One case, diagnosed January 27
- Canada: Two cases confirmed, first case January 25
- Australia: Five cases, first case January 25
- Malaysia: Four cases, first case January 25
- France: Three cases, first case January 24
- Nepal: One case, first case January 24
- Vietnam: Two cases, first case January 24
- Singapore: Five cases, first case January 23
- Macau: Five cases, first case January 22
- Hong Kong: Eight cases, first case January 22
- Taiwan: Eight cases, first case January 21
- USA: Five cases, first case January 20
- South Korea: Four cases, first case January 20
- Japan: Five cases, first case January 16
- Thailand: 14 cases, first case January 13
It has been difficult to contain because it appears to spread by coughing, sneezing and close personal contact, and may even pass on before someone has symptoms.
Many people only become mildly ill and might not notice anything is wrong with them, making them more likely to pass the infection on.
And there have also been what are called ‘super-spreading’ events in which one person can infect multiple others before they recover, speeding up transmission.
Fears of the coronavirus’s spread around the world have grown exponentially over the past week as the number of patients infected has soared from just 308 on January 21 to more than 4,500 on January 28.
Countries all over the world are taking extraordinary steps to stop the coronavirus reaching their shores.
Hong Kong today said it would stop trains and ferries, Russia and Mongolia have closed land borders with China and airport screening is in place globally.
Thailand is screening all passengers from China at its airports and has planes on standby to retrieve an estimated 64 people who are stranded in the locked-down Hubei region.
Thailand is a top destination for Chinese tourists and there have been 22,000 visitors from Wuhan alone during January, Sky reported.
And it is travellers who have bumped up the country’s virus count.
All but one of the confirmed coronavirus patients there have been Chinese nationals visiting from the Wuhan area.
In fact, five of them were members of a single family from Hubei aged between six and 70. A sixth declared recently came from the neighbouring Chongqing province.
But tourism this year is expected to take a hit because of the outbreak, with forecast visitor numbers down from 11million in 2019 to 9million this year.
WHAT DO WE KNOW ABOUT THE DEADLY CORONAVIRUS IN CHINA?
Someone who is infected with the Wuhan coronavirus can spread it with just a simple cough or a sneeze, scientists say.
At least 106 people with the virus are now confirmed to have died and more than 4,500 have been infected in at least 18 countries and regions. But experts predict the true number of people with the disease could be 100,000, or even as high as 350,000 in Wuhan alone, as they warn it may kill as many as two in 100 cases. Here’s what we know so far:
What is the Wuhan coronavirus?
A coronavirus is a type of virus which can cause illness in animals and people. It is an RNA virus (RNA is a type of genetic material called ribonucleic acid), which means it breaks into cells inside the host of the virus and uses them to reproduce itself.
This coronavirus from Wuhan is one which has never been seen before this outbreak. It is currently named 2019-nCoV, and does not have a more detailed name because so little is known about it.
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 seeing cases 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 4,500.
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.
Where does the virus come from?
Nobody knows for sure. 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 the virus in Wuhan came from people visiting or working in a live animal market in the city, 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.
Bats are a prime suspect – researchers at the Chinese Academy of Sciences said in a recent statement: ‘The Wuhan coronavirus’ natural host could be bats… but between bats and humans there may be an unknown intermediate.’
And another scientific journal article has suggested the virus first infected snakes, which may then have transmitted it to people at the market in Wuhan.
Peking University researchers analysed the genes of the coronavirus and said they most closely matched viruses which are known to affect snakes. They said: ‘Results derived from our evolutionary analysis suggest for the first time that snake is the most probable wildlife animal reservoir for the 2019-nCoV,’ in the Journal of Medical Virology.
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.
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.
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.
There is now evidence that it can spread third hand – to someone from a person who caught it from another person.
What does the virus do to you? What are the symptoms?
Once someone has caught the virus it may take between two and 14 days 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 – at least 97 per cent, based on available data – will recover from these without any issues or medical help.
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.
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, yesterday 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 so far killed 81 people out of a total of at least 2,800 officially confirmed cases – a death rate of around three per cent. This is a higher death rate than the Spanish Flu outbreak which, in 1918, went on to kill around 50million people.
However, experts say the true number of patients is likely considerably higher and therefore the death rate considerably lower. Imperial College London researchers estimate that there were 4,000 (up to 9,700) cases in Wuhan city alone up to January 18 – officially there were only 444 there to date. If cases are in fact 100 times more common than the official figures, the virus may be far less dangerous than currently believed.
Experts say it is likely only the most seriously ill patients are seeking help and are therefore recorded – the vast majority will have only mild, cold-like symptoms. For those whose conditions do become more severe, there is a risk of developing pneumonia which can destroy the lungs and kill you.
Can the virus be cured?
The Wuhan coronavirus cannot currently 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, 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 has not officially been confirmed as either an epidemic or a pandemic yet. This is likely because, despite the global concern, the number of people who have been confirmed to be infected is still relatively low.
A pandemic is defined by the World Health Organization as the ‘worldwide spread of a new disease’.
An epidemic is when a disease takes hold of a smaller community, such as a single country, region or continent.
