Perhaps you remember, I wrote an article earlier detailing what is an asymptomatic person. In the article, there is still one of the biggest outstanding cases-those who have been infected with the virus for more than 28 days and still have no symptoms, that is, those with “long-term asymptomatic infections”, how long can the virus last on them? Does it still have the ability to spread? (For more analysis, please refer to the awkward article “ Pursuing asymptomatic ｜ An article to understand the new challenges brought by asymptomatic people without panic , 2020-04-10, Surging Business School)
This is a very important issue. If this problem cannot be understood, people ’s panic will not be completely eliminated.
One of the most worrying results is that if the long-term asymptomatic infected person still has the ability to infect, then the society will face a very difficult ethical dilemma, namely long-term asymptomatic Should infected people be quarantined? How long will it be isolated?
Now, the answer to this question is finally coming out, and a heart hanging by many people has finally been put down. The people of Wuhan once again contributed to China and the world. We have also used real data to fight back the rumors and plantings of many conspiracy theorists. Below, I will explain in detail how this hard-won achievement has been made.
How long will people with long-term asymptomatic infection continue to carry the virus? Does it have or how strong is the infectivity?
To answer these questions, there is only one solution, which is to do a large-scale nucleic acid test in a population who has experienced new coronary pneumonia. The scale of this test must be sufficient Big, so that you can get convincing data.
In addition, it is necessary to wait for a long period of time before the epidemic in this population has been fully screened before the purpose of judging the situation of long-term asymptomatic infections can be achieved. There is no better city in the world than Wuhan. The resident population of Wuhan is about 11 million. If we can carry out continuous nucleic acid tests on these 11 million people and form a trend chart of the proportion of long-term asymptomatic infections since the lifting of the ban on the city on April 8, then we You can answer the questions that people care about most convincingly.
However, it is not easy to test nucleic acids for millions of people! From the outbreak of the new crown
