Shi Zhengli, a researcher at the New Crown Virus Research Institute of the Chinese Academy of Sciences, pointed out in an interview yesterday that the process of traceability of the virus may be long, or there may never be answers.It is necessary to continuously find it to achieve the purpose of the desired.

According to the Beijing News, Shi Zhengli was one of the parallel forums of the Zhongguancun Forum yesterday. The Global Science and Life Health Forum delivered a speech entitled by the new crown pneumonia pathogenic pathogenesis and possible origin.In an interview with the media, she said that the team was tracing the natural source of the coronal virus, but the question of which intermediate host and how to spread from nature to humans by viruses still have no answer.

Talking about public opinion's incomprehension of scientific research and scientists, Shi Zhengli said that a lot of things scientists do are not understood by the public, and everyone looks useless.In fact, human knowledge is accumulated little by little. Without the accumulation of knowledge of previous generations, we can't know so much now.It is precisely because many people have accumulated for so many years and one generation that have expanded human cognitive boundaries for nature.

When Shi Zhengli reviewed the process of obtaining the sample, we said: We have cooperated with Wuhan Jinyantan Hospital. On the evening of December 30, 2019, we received 7 alveolar irrigation fluid samples from patients with pneumonia patients from Jinyintan Hospital.Is there a coronary virus infection in the sample?Because our laboratory has been doing coronary virus for a long time, they hope I will help them confirm.

Shi Zhengli said that later, the nucleic acid detection method of all coronary viruses and all SARS -related coronary viruses was used to use laboratory reserves to detect positive coronary virus in the sample.However, to further determine which coronary virus must be used as high -throughput sequencing. By further sequencing, we find that this is a new type of SARS -related coronary virus, which is now named the new coronary virus (also known as coronal virus).

Shi Zhengli also said that the traceability of the virus is a very important thing, because coronal virus is a new type of coronary virus, so its source and how it spreads into human society is very important.However, it is very difficult to figure out that the traceability of the virus is very difficult, depending on the study of epidemiology and molecular evolution.

After obtaining the new crown virus genome sequence, Shi Zhengli's team compared the public data and some of the data they had not yet published. Later, a sequence sequence was found in the database mdash; mdash; this sequence was found in a mine in Yunnan in 2013 in 2013.Its genomic sequences of genomic sequences and coronal viruses are as high as 96%, so we speculate that the originally evolutionary source of coronal virus is a bat.

Although other research teams have also detected SARS -related coronary viruses that have a close relationship with coronal virus in pangolins, these genome sequences show that their evolutionary relationship is still a certain distance from the coronary virus.

Shi Zhengli emphasized that we know that traceability is important, but it may never be found.When SARS broke out at that time, the scientists lock in the direct source of the nine that traded on the market for the first time, but it took us eight years to find the most primitive source of SARS in a mine in Yunnan.It is necessary to continuously find it to achieve the desired purpose.

Shi Zhengli also said that the long -term monitoring of natural epidemic diseases is very important. Early detection, early warning, and early intervention should be achieved, and infectious diseases should be contained in the bud stage.This is not a question that can be done, it is a question we want to do for a long time.

Regarding the voices of question from society, Shi Zhengli said that a lot of things scientists do are not understood by the public. Everyone looks useless.In fact, human knowledge is accumulated little by little. Without the accumulation of knowledge of previous generations, why do we know so much now?It is because many people have accumulated for many years and generations to expand human cognitive borders of nature.
