Before answering this question, Desheng will share with you a basic knowledge of microorganisms: the dominant infection rate, that is, how many people will show symptoms after being exposed to pathogens. Correspondingly, there is a recessive infection, that is, after a person is exposed to the pathogen, he is fine, and he may be immunized once because of this, but at the same time, it is also possible that his own immune system cannot defeat it, causing no obvious symptoms, but the virus has always been Low-level replication, and continuous detoxification.
Now that the new crown virus is still spreading, someone asked if someone was infected with new crown pneumonia without knowing it, and then healed on their own? Through the introduction to the basic knowledge of microorganisms at the beginning, I believe you will answer correctly: this situation should exist. Today Desheng will talk to you about this issue.

From the current point of view, there are two situations after the new coronavirus infects humans. One is the new coronavirus pneumonia infection, which is more common. The other is asymptomatic infection. Academician Zhong Nanshan said in an interview with CCTV News: There are not many asymptomatic infections, but there are. So, what is an asymptomatic infection?
According to the new coronavirus infection pneumonia case monitoring program, asymptomatic infections have no clinical symptoms, but respiratory specimens tested positive for the new coronavirus pathogen. If this asymptomatic infection person has strong immunity, the new coronavirus invades the body, but it is not enough to cause the symptoms of new coronavirus pneumonia such as fever, cough, fatigue, diarrhea, etc.; before long, the new coronavirus is completely affected by the autoimmune system Eliminate and heal itself. Therefore, in theory, this kind of situation may exist in theory that someone is infected without knowing it, and then heals himself.
So, is this asymptomatic infection actually contagious? The pneumonia diagnosis and treatment plan for the new coronavirus infection clearly states that asymptomatic infections may also become the source of infection. At present, many asymptomatic infections have been found. They have no clinical symptoms, but can transmit the virus to others. These asymptomatic infections may be in the incubation period, or they may only carry the virus and will not get sick at all, or they may only have very mild symptoms. They are not aware of it, or even pneumonia will not appear. With the current level of technology, it is difficult Was checked out. Asymptomatic infections who have no symptoms but are contagious are also the most difficult place to prevent and control the current epidemic. Some experts pointed out that although there are asymptomatic infections, but the number is small and the infectious power is not strong, as long as protective measures are taken, there is no need to worry too much.
In this critical stage of epidemic prevention and control, everyone should not forget when the epidemic has improved. It is important to improve immunity. Not going out, not gathering, wearing masks, washing hands frequently, and ventilating are still preventing the new coronavirus, and also responding to it. Effective measures for asymptomatic infected persons. In addition, we also need to cooperate with local policies to actively carry out nucleic acid testing.
