All 56 victims of the new virus died in China, but the number of cases has already exceeded 2 thousand persons around the world.

From a new type of coronavirus 2019-nCoV has already killed 56 people. This is with reference to the data published by the Chinese authorities, reports the Chronicle.info with reference to .net.

The data also suggest that all the deaths recorded in China, but more than 2 million people worldwide have been infected with the novel coronavirus.

President XI Jinping said during the Politburo meeting that China faced a serious situation, and health authorities worldwide are struggling to prevent a pandemic.

Recall that in 25 provinces of China declared the highest level of emergency response related to public health. The total population in these areas exceeds 1.2 billion people.

It is known that the virus has spread abroad, including to South Korea, Japan, Singapore, Thailand, Vietnam, USA, France and Australia.

Coronaviruses are genetically similar group of viruses that infect higher animals (mammals, birds, many reptiles), including humans.

In this family there are already six pathogenic for the human species: sometimes, this infection is asymptomatic, sometimes manifested in the form of a cold. In severe cases, the infection causes pneumonia, which can result in death of the patient.

Scientists have found that the new coronavirus 2019-nCoV is a kind of SARS virus (severe acute respiratory syndrome or SARS), which also emerged in China in 2002-2003 affected more than eight thousand people in 37 countries. Then killed 774 people. He was the seventh of the dangerous strain.

Coronaviruses have come to man from animals, presumably from bats. The likely focus of the spread 2019-nCoV is the seafood market in Wuhan, which is on the eve of the Chinese New year was full of wild animals: foxes, wolves, bats and even viverrini.

Most of the first hospitalized patients were somehow connected with the market of Wuhan. Scientists are not exactly revealed animals that are carriers of 2019-nCoV.

A group of Chinese scientists under the leadership Singana Lee from Wuhan University bioengineering has put forward his version of events: bats infected your coronavirus snakes, and their body two viruses exchanged their plots.

And about two years ago there was a hybrid virus 2019-nCoV, which by December 2019 reached out to people. Estimated owners researchers believe two snakes: the South China MNOGOPROFIL krayt and Chinese Cobra. In favor of this theory is the fact that both of them were sold at the Wuhan seafood market.

However, researchers from the Wuhan Institute of Virology has allocated the 2019 coronavirus-nCoV have a very sick patient and said that the closest structure to the coronaviruses of bats.

Also in the journal Nature has published an editorial with comments virologists from around the world. They all agree that snakes are unlikely to be the source of the coronavirus. Most experts shodyatsya the opinion that the virus came from a mammal.

In early January, Chinese scientists published in the database GenBank complete genome 2019-nCoV, to help doctors in other countries to identify the disease.

Under the microscope the virion coronaviruses appears as an oval with many small spines, obrazovannyh a special protein, which provides the fusion of the virus with the cell membrane of the attacked organism.

It is still unknown whether the virus is transmitted from person to person by airborne droplets. While the transmission is limited to family groups and health workers caring for the infected.

Michael Letko, and Vincent Munster of the U.S. National Institute of Allergy and infectious diseases found that 2019-nCoV, like its predecessor SARS enters the cage through the human ACE2 protein.
