The outbreak of the new crown virus has attracted global attention and attention, and the research on the traceability of the virus has also attracted much attention. Recently, the mainland has made important progress in the study of the traceability of the new crown virus. At a press conference held by the State Council's new office, Professor Tong Yigang, dean and dean of the School of Life Sciences at Beijing University of Chemical Technology, introduced the mainland's research on the seafood market in South China, and said that the new coronavirus is likely to originate in humans.
Huanan Seafood Market was the first place for the coronavirus outbreak. From the genetic sequencing analysis of the virus samples, the genetic sequence of the virus was highly similar to that of the patient at that time, indicating that the new coronavirus was probably transmitted from wild animals to humans and further spread and spread in the Huanan Seafood Market. The researchers tested for the novel coronavirus and metagenomic sequencing on environmental samples and frozen animal samples in the market and found that all the animal samples collected were negative, but 73 environmental samples were positive. In addition, in this process, the researchers also isolated three strains of the virus from environmental samples, which are highly similar to human virus sequences, further suggesting that the new coronavirus is likely to originate in humans.
These findings have great implications for our understanding of the new coronavirus. First of all, the new coronavirus is transmitted from wild animals to humans, which also prompts us to strengthen the control of wild animals and avoid wild animals becoming a potential source of the virus. Secondly, the poor sanitation conditions in the Huanan seafood market may accelerate the spread and spread of the virus. This also reminds us to maintain hygiene in our daily lives and strengthen hygiene management and supervision in public places. In addition, the traceability study of the new crown virus also shows that the construction of the global public health system needs to be strengthened urgently, and it is necessary to further improve the ability of disease early warning and response, strengthen international cooperation, share information and resources, and jointly promote the development of global public health.
It is worth noting that the scientific difficulties and controversies are about the origin and transmission path of the virus. Although viral genome sequencing and comparative analysis have confirmed that the new coronavirus is a virus in nature, there is no definitive answer as to how it first spread to humans. Some experts believe that the virus may have spread from wild animals to humans, while others believe it may have leaked from a laboratory. Regarding the hypothesis of laboratory leaks, some believe that this possibility is very unlikely, because laboratories generally have strict safety measures and protective measures, and no obvious traces of gene editing or modification have been found in the genome of the new coronavirus. However, there are also those who believe that this possibility is not completely ruled out and that investigation and research need to continue.
In addition to scientific difficulties and controversies, research on the origin of the new coronavirus also faces the problems of political interference and insufficient international cooperation. Due to the severity and global impact of the new crown epidemic, the research on the origin of the new crown virus has become a political topic and the focus of international competition. Some countries and regions have tried to use this opportunity to attack and smear other countries, and even interfered with and hindered the conduct of traceability research. At the same time, due to issues related to data sharing, sample collection and technical exchange, there are also some difficulties and deficiencies in cooperation between countries in the research on the traceability of the new coronavirus.
To sum up, the research on the traceability of the new coronavirus is a complex and important scientific issue, which requires the joint efforts and scientific cooperation of all parties around the world to solve. We need a deeper understanding of the origin, spread and evolution of viruses in order to better respond to future outbreaks. At the same time, we also need to strengthen international cooperation and information sharing, and build a more robust and efficient global public health system to cope with global public health risks and challenges.
