Guide: The results of the Wuhan research in June 2020 cannot be applied directly to the current asymptomatic infection of Omikon, and the two do not have the same sex.

Recently, the information about "those with no symptoms of new crown virus infection cannot cultivate live viruses" has been continuously reposted and spread, which has caused many people to think that the asymptomatic infected infected infection of the infection of the infected virus in the body is not infectious, and it is not infectious. It is even thought that there is no need to prevent and control the asymptomatic.

In fact, the information about "the results of the virus training of 300 asymptomatic infections in Wuhan are negative", published in 2020.

On June 8, 2020, the official website of the Wuhan Health Commission issued a message saying that in order to make the normalized epidemic prevention and control work more accurate, the management of asymptomatic infected people is more scientific, so that the people of the country and the people of Wuhan are more assured. Wuhan Wuhan is more assured. Wuhan Wuhan is more assured. From May 14, 2020 to June 1st, the 300 asymptomatic infections found in nucleic acid testing and inspection were concentrated in the inspection and detection of their sputum and pharynxes. None of the samples were cultivated.

This information also states that experts believe that the asymptomatic infected virus is not trained in the sputum and pharynx samples, indicating that the virus content in the sample is extremely low, or there is no pathogenic "living virus". At the same time, toothbrushes, mouth cups, masks, towels and other individual supplies such as toothbrushes, cups, masks, towels, etc. of 300 asymptomatic infected people are negative; It shows that the asymptomatic infection discovered at the time of Wuhan was not contagious.

"The research we did in 2020 provided a scientific basis for unblocking Wuhan after unblocking Wuhan." A expert involved in this research said.

The expert said that at the end of the Wuhan epidemic, the spread of the new coronary virus had completely blocked or approached completely. Among the 10 million people, the positive detected positives were both positive at the end of the restoration period and a certain number of false positives. In order to provide a scientific basis for unblocking and exclude risks, they carried out virus training for these people, and found that there were no living viruses in their bodies.

On April 8, 2020, Wuhan was unsealed 76 days after the "sealing city" and lifted the management and control measures of the departure Hubei. "The asymptomatic of the nucleic acid positive after the unblocking of Wuhan is mostly after the recovery. From the perspective of the virus infection, it is a post -infection, not the early stage of the virus infection." A clinical expert in infectious disease said.

The asymptomatic non -symptoms of nucleic acids in Wuhan's research in 2020 are not the same as the asymptomatic people currently under Omikon.

The above -mentioned clinical experts of infectious diseases stated that at present, Omikon's infection is not asymptomatic in the early stage of infection, with a living virus in the body, and the load is higher than the previous variants. One piece, this is also an important factor in Omikon's fast spread.

When the Omikon mutant strain appeared, the initial scientific research found that the virus load of the Omikon infected person was 8 to 16 times that of the infection of the Delta strain, and most of them were asymptomatic. The scientific community believes that there are two main factors to alleviate the symptoms of Omikon infected. One is that Omikon's pathogenicity is weakened, especially the infection of the lungs is one -tenth of the past. And the existence of natural infections, it has a protective effect on the severe illness.

Because of this, the results of Wuhan's research in June 2020 cannot be directly applied to the current asymptomatic infection of Omikon, and the two do not have the same sex.
