CCTV reporter interviewed Academician Zhong Nanshan 丨 Unconventional cases are a few that require close observation

Today (24th), CCTV reporters conducted an exclusive interview with Academician Zhong Nanshan on the recent “unconventional” cases of new coronary pneumonia, as well as public downgrade of emergency response levels in various places.

Chen Xuting, CCTV reporter: When everyone describes the new crown virus recently, they like to use one word to say that it is "sly". Because there are now some "asymptomatic infections", some cases have an incubation period of more than 14 days, and some people have been discharged from the hospital and re-examined to find that the nucleic acid is positive again. Negative, but there are residual viruses in the feces ... How should a situation like this be understood by the public?

Zhong Nanshan, academician of the Chinese Academy of Engineering, leader of the high-level expert group of the National Health and Health Commission: Our current standard is to use a throat swab to test negative, which is a standard. However, some patients do have anal swabs or feces, and there are still fragments of nucleic acids detected, not live viruses, which are two different things. In addition, there are a few patients who have undergone some re-examination after being discharged, and some of them have positive nucleic acid fragments. I am not surprised. After continuing to observe for two weeks, after a long period of quarantine, check again, but it is still worth watching.

CCTV reporter Chen Xuting: Do you say that this situation is an example?

Zhong Nanshan, academician of the Chinese Academy of Engineering, leader of the high-level expert group of the National Health and Health Commission: A few, can't be said to be an example. For example, we are now negative for the throat swab test twice, without any symptoms, and the temperature and CT are good in all aspects, so that we can be discharged from the hospital and quarantine afterwards. Once it is said that the policy is changed and this indicator is changed again, anal swabs must be completely negative, and many patients will have a backlog and the ward will not be able to turn around. We still have to observe closely, there is a hierarchical management of these (patients).

Academician Zhong Nanshan: The time has come to lower the response level

CCTV reporter Chen Xuting: In recent days, various provinces have also lowered their emergency response. Do you think this time has not come? At 9 o'clock this morning, Guangdong also adjusted the first-level response to the second-level response. What is the basis for Guangdong to reduce this?

Zhong Nanshan, academician of the Chinese Academy of Engineering, leader of the high-level expert group of the National Health and Health Commission: I think it's here. First, in Guangdong, it should be that the number of new patients in most cities and regions has been significantly reduced and greatly reduced. This is a prerequisite; in addition, the awareness of prevention and control has been greatly strengthened, so the primary prevention and control is not In terms of any region, we are actually in the second-level state, and the first-level prevention and control measures, and no matter where we are, we must adopt the first-level (response). So the second level means classification processing, three types, classification processing, hierarchical partition classification processing, which is the core.

I think it's suitable, it's suitable now. Because on the one hand, the tightness should be tight, and the looseness should be loose. Such circumstances are beneficial to the development of production. I think so.

Academician Zhong Nanshan: The prevention and control consciousness must be maintained for a long time, and the virus must be studied for a long time.

CCTV reporter Chen Xuting: In the interview last time, you mentioned that we must be prepared to deal with coronaviruses for a long time. Do coronaviruses include this new type of coronavirus? In addition, if we want to do a good job with As it prepares for dealings, is it necessary for the public to maintain such prevention and control measures?

Zhong Nanshan, leader of the high-level expert group of the National Health and Health Commission and academician of the Chinese Academy of Engineering: The level of prevention and control must be reduced, and awareness must be maintained. This time it was transmitted from person to person, so whenever a coronavirus infection appeared, I also told the World Health Organization that I said that we must be highly vigilant to human infectivity, so the awareness of prevention and control needs to be maintained, and the level of prevention and control can be changed completely. .

Academician Zhong Nanshan: Remember the lessons and long-term research on viruses

CCTV reporter Chen Xuting: For medical staff and scientific researchers, what will they do if they deal with coronavirus for a long time?

Zhong Nanshan, leader of the high-level expert group of the National Health and Medical Commission and academician of the Chinese Academy of Engineering: In my opinion, in 2003, I had to do research at that time, but after that, I felt that there was nothing, and it passed. Most people simply No long-term research has been done, just a few people. When it came to MERS, a regional disease, after a period of climax in 2015, many later also passed. Therefore, most researchers do not carry out long-term research on the infection of coronavirus. Because of this, this is the state now. After the sudden arrival, it can be said that medical staff can use this to describe the use of targeted drugs, and they are at a loss.

Chen Xuting, CCTV reporter: Do you think you need to put more effort in this area?

Zhong Nanshan, the leader of the high-level expert group of the National Health and Health Commission and an academician of the Chinese Academy of Engineering: Of course this is the case, and we cannot say that we will let go in the past and wait until the next time. Nope. This has been done a lot. In fact, some studies have been based on SARS, and they have accumulated a lot of experience in their treatment.

Academician Zhong Nanshan: Our understanding of the new crown virus is very preliminary

CCTV reporter Chen Xuting: So I heard you say that, at what stage do we know about the new coronavirus?

Zhong Nanshan, leader of the high-level expert group of the National Health and Medical Commission and academician of the Chinese Academy of Engineering: It is very preliminary. Very preliminary. Of course, you can say this. You know that SARS coronavirus in 2003 has no effective medicines, and there are not many specific drugs for treating viruses, targeted drugs, but we are discussing them now.
