On June 15, Beijing announced 36 new cases infected by coronavirus. This is a sudden emergency. And the local government reacted quickly and timely to the emergency.
In terms of the composition of the virus, it does not resemble the strains of the virus that were prevalent in Beijing a month or two ago. In other words, it doesn’t belong to the ones that were prevalent in China before. The key strains prevalent in each country can be seen through the neo-coronavirus gene sequences that are publicly available globally through the WHO platform. Virologists compared it to strains prevalent in China and to strains prevalent around the world, and the comparison of key loci found that it had the most probably from the main strain circulating in Europe.
The first phase of the virus tracing investigation of the outbreak in Beijing went smoothly, and it was quickly established that the virus originated from the European epidemic strain. There are two significant aspects of the tracing work. First, it is of great significance in terms of scientific understanding, as finding the source is an important part of scientific understanding of the new coronavirus, and it is also an important part of our understanding of the objective and objective nature of the virus. part of the world. Secondly, the public health significance of the virus’ traceability is of great importance to the prevention and control of infectious diseases.
Only by finding the source of the new coronavirus and understanding how it suddenly developed into a pathogenic virus that causes such serious harm to humans can we. The answer to the question of whether corona pneumonia will recur in the future is the concern of whether it will make a comeback in the future after the epidemic is controlled.
For the pandemic, which has been endemic for less than six months, our knowledge is still very limited. The available scientific evidence suggests that the neo-coronavirus is of natural origin. Traceability of the virus will be a long process. In particular, as the new coronavirus is still wreaking havoc around the world, there is an urgent need for countries around the world to work together to control the spread of the epidemic as soon as possible.
