There are six coronaviruses were known to infect people before the latest discovery

The Number of people infected by The Mystery of the emerging virus in China is far greater than the official figures suggest, said the researchers, BBC.

There have been More Than 60 confirmed cases of the new coronavirus, UK but experts figure to estimate closer than 1,700.

Two People are known to have died of the disease of the respiratory tract, which appeared in Wuhan city in December.

"I'm considerably more worried than I said a week ago," the outbreak of the disease scientists Prof Neil Ferguson ,.

The Work was carried out by the MRC center for global Infectious disease analysis at Imperial College London, advises bodies including the British government and The World health organization (WHO).

Singapore and Hong Kong have been screening air passengers, the Wuhan, and the US authorities to similar actions from Friday at three major airports in San Francisco , Los Angeles and New York announced.

How is calculated the numbers?

The key note, to the extent of the problem identified in the cases, in other countries.

While the outbreak is centered, on the Central-Chinese city of Wuhan, there were two cases in Thailand and Japan.

"is causing The worry," said Prof Ferguson.

He added: "have To Wuhan, exported three cases to other countries, would mean there is still a lot more cases would have been reported as. "

It is impossible to state the exact number, but the outbreak of the modeling, which can give to The Virus , The Local population and the flight-data, an idea.

Wuhan International Airport serves a population of 19 million people, but only than 3,400 per day travelling internationally.

The detailed calculations that came prior to the publication in a scientific journal with a figure of 1,700 cases.

What does all this mean?

Prof Ferguson said it was "too early to be alarmist," but he was "much concerned" as a week ago.

say Chinese officials, there were no cases of The Virus spread from one person to another.

Instead, they say, has The Virus crossed the species barrier and come from infected animals to a fish and wildlife market in Wuhan.

Prof Ferguson argued: "the people should consider the possibility of significant human-to-human transmission is more serious than you previously have.

"It would be unlikely, in my mind, given what we know about corona viruses, animal exposure to the main cause for such A Number of human infections. "

to Understand how a new virus spreads, is an important part of the assessment of threat.

The Who said the China office, the analysis was very helpful and would help the officers plan the response to the outbreak.

"still remains Much to understand about the new coronavirus," it said. "Not enough is known to draw final conclusions about how it is transmitted, clinical features of the disease, the extent to which it has spread, or its source, which remains Unknown . "

The outbreak occurred in The City of Wuhan, to the South of Beijing, What The Virus is?

Viral samples were taken, the analyses of patients and in the laboratory.

And officials in China have closed, the infection is a coronavirus.

coronaviruses are a large family of viruses, but.

At the mild end of it cause the common cold, but severe acute respiratory syndrome (Sars) is a coronavirus, killed 774 of the 8,098 people infected in an outbreak that began in China in the year 2002.

analysis of the genetic code of the new virus shows it is more closely with the Sars epidemic, than any other human coronavirus.

The Virus causes a lung inflammation in some patients and was fatal in two of them.

What other experts say?

Dr. Jeremy Farrar , Director of Wellcome-medical research charity, said: "There is more to come from this epidemic.

"uncertainty and gaps remain, but it is clear that there are some levels of person-to-person transmission.

"We are starting to hear more cases in China and other countries, and it is likely, as this model shows, that there are many more cases in A Number of countries. "

Prof Jonathan Ball of Nottingham University said: "What is really important until it was the laboratory used to test, it is very difficult, a real number in the cases that there are.

"But that's A Number we should take it seriously until we know otherwise, 41 animal-to-human 'Spillover effects' is stretching it a little, and there is probably more underlying infection, as has been detected so far. "
