Positive for imports
A variety of imported aquatic products, the test is positive. According to media reports: According to the recent announcement issued by the General Administration of Customs, aquatic products imported from many countries can detect positive nucleic acid tests for the new crown. Why is it that these foods containing the coronavirus can be transported from foreign companies to China, is it negligent or deliberate?
Mutant virus
The coronavirus has been ravaging the world for a long time, from the original original coronavirus, to the new crown variant virus, Alpha, Beta, Gamma and Delta, and now the most rampant Amy Kerong. During this period, our scientists have also successfully developed nucleic acid tests for the new crown virus and vaccines to prevent the new crown virus infection.
COVID-19 RNA
However, because the new crown is an RNA virus with extremely terrible variations, each mutation may produce a completely new virus, and each mutation may lead to the failure of existing vaccines. So the same goes.
Unlike viruses, the work of developing vaccines requires a lot of time and effort, but the virus mutation is very simple, only need to stay in a certain place for a while, or fuse with a different strain to form a new coronavirus strain.
Good at camouflage
The new strain means that its body has changed, and even if there is an antibody to the virus inside our body, it may fool the immune system and successfully invade the human body, because the new strain only needs to be slightly changed, and the immune system cannot recognize it.
The S protein of the new crown virus is very powerful, and the S protein is the key to the virus invading the cell. Comparing these variants of the new crown virus, you will find that the current Omiljung is many times more powerful than the original new crown virus.
It is worth mentioning that although the new crown virus has been raging around the world for such a long time, we are still fighting the virus, unlike in the medieval period. In the Middle Ages, there was a terrible virus that almost destroyed the entire human civilization, that is, the Black Death, and it is reported that the Black Death is still the virus event that caused human death and spread the largest number.
Change the nature
Through the research of scientists, it has been found that although the new crown virus is constantly mutating, in addition to its stronger infection speed and ability, its viral toxicity has not increased, on the contrary, it is still weakening. If one day the new crown virus suddenly loses its toxicity and only increases its infectivity, then its nature will become the same as that of the cold virus, and it will no longer be a threat to human beings.
Because of this, under the constant mutation of the new crown transmission ability, but its toxicity has not mutated, most people do not take it seriously, to say that the simple point is to lie flat, coexist with the virus, and create the so-called natural immunity of the herd.
A breeding ground for viruses
Most viruses are afraid of heat and cold, the same is true of the new crown virus, the study found that the new crown virus in food, can survive for nearly 8 days, that is to say, during this time, once you touch the food with your hands, you may infect the virus to yourself.
This is especially true for cold chain frozen aquatic products. The colder the conditions, the more the hotbed of the new crown virus, which can remain active at low temperatures. Then in the processing of imported food, if the processed worker contains the new crown virus, then the virus on his body will spread to the food, and then arrive in China through transportation, which is imported food.
Although foreign companies have repeatedly said that the processing environment of these foods is very good, there is no so-called virus, and the nucleic acid tests of workers are negative. To put it nicely, the result is a test in China - positive for the new crown virus.
This article summarizes
Have we forgotten the battle against the virus in 2020 that lasted for months? Officials have always advocated that foreign imports and internal non-proliferation, internal anti-proliferation is easy to solve, but it is difficult for foreign imports, because even if this batch of imported food is repatriated, will the next batch of imported food still contain viruses? This raises the question, do we still want to eat imported food?
