 Science: who dissatisfied with the new crown named sars-cov-2


Novel coronavirus pneumonia was named COVID-19 in February 11th by WHO director general Tan taisai in Geneva, Switzerland. Covid-19 is a name for a disease, not a virus that causes it. The virus has a novel coronavirus, 2019-nCoV, which is a new coronavirus in 2019.

But just before the World Health Organization director general Tan Desai ended his press conference, the International Committee for the classification and nomenclature of viruses also named the pathogen of the disease (pathogen). The novel coronavirus research team of the committee published a paper in the preprint platform BioRxiv, pointing out that the International Classification Committee of the virus coronavirus research group (CSG) has decided that the new coronavirus (virus) is a variant that causes the outbreak of severe acute respiratory syndrome (SARS) coronavirus in 2002-2003 years. Therefore, the new pathogen was named severe acute respiratory syndrome coronavirus 2, or sars-cov-2.

It is worth noting that, although the coronavirus research group of the International Committee of viral classification named the virus sars-cov-2, its Chairman John ziebuhr believed that the name (sars-cov-2) was not related to SARS (severe acute respiratory syndrome, also known as SARS). uff08ThereisnolinkbetweenthenameandthediseaseSARSuff09

Who dissatisfaction, naming misunderstanding

WHO announces the novel coronavirus pneumonia is named COVID-19.

According to the science website, the World Health Organization is not satisfied with the name sars-cov-2 and does not intend to use it.

Misunderstandings about the names of viruses and diseases soon arose.

A reporter who listened to the news conference of World Health Organization director general Tan Desai tweeted that the virus finally has a name, covid-19, and he corrected the wrong statement shortly.

Although naming is a small problem in the growing public health crisis, even some virologists have been taken aback by this seemingly contradictory statement, the science website said.

Well, within a day, the same virus had two names, Marion Koopmans of Erasmus medical center in the Netherlands wrote on twitter. It sounds like some people need to meet to solve problems.

Two different naming principles

The difference between the nomenclature comes from a completely different route followed by who and CSG.

A spokesman for who told sciencewebsite that who experts did not consult with Chinese officials and that naming the disease followed some generally accepted principles. For example, disease names cannot refer to people, people or geographical location, which may cause stigmatization; they should not include animal names, which may be misleading, because some animal viruses cross species and become human pathogens, as sars-cov-2 did. The name chosen by who, covid-19, is the abbreviation for coronavirus disease in 2019. (the first known case of pneumonia caused by the virus infection occurred in Wuhan, China, in December 2019) this name will not offend anyone, and if other coronaviruses spread from animals to humans in the next few years, it can be recycled.

John ziebuhr, a virologist at the University of Giessen in Germany and chairman of the coronavirus research group (CSG) of the International Committee on viral classification, said that CSG took a scientific approach to the naming of viruses. According to the recent genome sequencing, the new virus belongs to the same species as the virus that caused the SARS epidemic in 2002-2003, which is called SARS related coronavirus.

Another CSG member, raoulde Groot of the University of Utrecht, added that species are difficult to define in a virus because the genome of the virus has been changing, but gorbalenyas team has designed such a system for the coronavirus, as described in two papers in 2012, which is generally accepted.

John ziebuhr said the virus may be novel to the rest of the world, but not to virus taxonomists, who named it sars-cov-2.

This is not the first time a virus has a different name than the disease it causes, according to science. For example, smallpox and variola virus, HIV and AIDS.

Chairman of CSG: the name of the virus is not related to SARS

John ziebuhr, chairman of CSG, said who had informed him that the name (sars-cov-2) was not appropriate in China, which had refused to compare the current crisis with the traumatic SARS epidemic. But ziebuhr said, its important to be clear that the name doesnt refer to the disease caused by the virus. This name (sars-cov-2) is not related to SARS. This is the difficulty facing who. .

Ziebuhr points out that hundreds of other viruses found in bats and other animals by Chinese researchers share the same species name.

Mike Osterholm, director of the center for infectious disease research and policy at the University of Minnesota, said he would not use the name sars-cov-2. We dont believe its an accurate name, its actually confusing a completely different disease (SARS) with this disease (covid-19), he said

But ziebuhr thinks many other researchers may start using the new name (sars-cov-2). The positive response I received from many colleagues, including Chinese scientists, he said It makes me believe that in a very short period of time, sars-cov-2 virus will be widely accepted by the research community and other fields.

Same day naming: uncoordinated coincidence

It seems a coincidence that two names appear almost at the same time.

Alexander gorbalenya, a virologist at Leiden University and the first author of the aforementioned biosiv virus naming manuscript, revealed that he sent the manuscript to biosiv on Friday. Yesterday afternoon (February 11), the manuscript didnt appear online, so he sent an email to biorxiv asking why there was a delay. It was posted in an hour, but I didnt know who would announce it

CSG President John ziebuhr said the manuscript was also submitted by CSG to a magazine for publication and sent to who. (Science Publishers have previously promised to share any new information about the virus with who immediately.)

But a who spokesman said the timing of the WHO announcement was not affected by the delivery of the manuscript.

John ziebuhr hopes to coordinate the work of the CSG team with who, just as it did when the Middle East respiratory syndrome associated coronavirus (mers COV) emerged in Saudi Arabia in 2012. At that time, the who, the Saudi government and other stakeholders agreed (the name) and actually made a joint statement. (all partners involved in naming agree to make an exception to the no place rule, saying that the Middle East is big enough that no particular group will be humiliated.)

Ziebuhr said such coordination is now impossible. Who was overwhelmed by what happened there and had no time, he said But he also said the naming needs to be made clear and scientists want clear guidance.

Koopmans, a member of the whos Disease Advisory Committee, said that ideally, the release of this information should be coordinated.. She called what happened on February 11th a bit confusing, but did not see it as a big problem.

Mike Osterholm, director of the center for infectious disease research and policy at the University of Minnesota, commented on the incident: I found that the whole naming situation was unfortunate, although both groups clearly knew that each other was working on it, but there was little coordination..

Our hope is to rethink the naming of viruses and diseases and try to reconcile them so that they are more similar, better able to describe the impact of the virus on humans, and able to integrate it into coronavirus virology.
