On April 12, Academician Zhong Nanshan accepted an exclusive interview with the People's Daily and made the latest response to the 12 issues.
1. It's not the time to pick the mask
Zhong Nanshan said that it is not the time to removing the mask.At present, the situation at home and abroad is very different. China has adopted very decisive measures, and has now entered the second stage of the epidemic, and some other major countries are still in the first stage of the upstart, and they are still rising upward.This means that the chance of people is very high, and the number of diagnosis has increased very quickly.Wearing a mask is still a very important self -protection method, and now it is too early to propose not to wear it.However, in areas where the epidemic is not serious, there are no places or open spaces, but they may not be worn.
2. Wuhan passed the level, but there is still the next level
For Wuhan unblocking, Zhong Nanshan said that Wuhan was unpacking, and I was also very happy.When the epidemic broke out, the central government made a decisive shot to control the traffic in Wuhan's urban traffic. It was very successful to take group prevention and group control measures in other places. In the history of epidemic prevention and control, this is also a feat.
Next still face two tests.One is how to prevent and control, restore work, and the other is an external defense input level.At present, abroad is still at the peak of outbreaks. Some major coastal cities in China, which are closely exchanged abroad, can easily be rolled in and have some epidemic conditions.The next level of Wuhan is also the country in the country, and it is necessary to pass through various prevention and control measures.
Third, the possibility of the second outbreak of the Chinese epidemic overseas input is small
Continuously appearing overseas input cases will cause community transmission and trigger the second outbreak of my country's epidemic situation?
Zhong Nanshan said that this is actually two problems. One is whether foreign input cases have spread, and the other is whether it will outbreak during the spread.The risk of overseas input case transmission must exist, especially cases that are positive or infectious symptoms of nucleic acid testing. Infectiousness is strong, which can cause virus transmission.
Will the outbreak of the epidemic?It is estimated that the possibility is relatively small.my country's group defense control has been sinking to the community. The residents of the community have a strong sense of self -protection, such as wearing masks, staying with people, and staying with people. Once someone has symptoms such as fever isolation.In general, the danger of communication in the community must exist, but the probability of the second wave of outbreaks in China is very small.
Fourth, talk about the global epidemic inflection point as early
Regarding the global epidemic, he said that from the global perspective, the epicenter of the epidemic was in Europe, especially Spain and Italy, and now includes Germany, France, and the United Kingdom.The biggest problem is the United States. In the last week, this week has increased at a rate of 10,000 or 20,000.Therefore, it is still early to look at the inflection point now.
Failure to the inflection point, it depends on whether the government can make a strong intervention.There are many unpredictable factors in other countries, so now let me predict the global inflection point, which is much more rare than predicting China.According to the current situation, it will take two weeks.
Fifth, the proportion of asymptomatic infected in China will not be very large
Zhong Nanshan said that asymptomatic infections will not occur out of thin air, and usually appear in two groups: First, in areas where the epidemic is relatively serious, people who have not showed symptoms but may have been infected for the time being.The other is the close contact of the confirmed case.They occupy less.
There are two concepts of asymptomatic infections. One is that there are no symptoms at first, but it will gradually develop to symptoms. This type is definitely contagious.The other is what we have discovered recently. There are always no symptoms during a long observation process, but nucleic acid testing is positive.We are studying such contagiousness.However, according to the characteristics of the new coronal virus, once symptoms occur, the contagiousness is relatively strong, so it is right to observe them as a group of people.
6. Most patients with Fuyang are not infected
Zhong Nanshan said that the so -called Fuyang should be a clip of nucleic acid rather than the virus itself.It is necessary to pay attention to the two cases. The first is whether the patient himself recurred. If the patient produces a strong antibody, it will generally not infected.As for whether Fuyang patients will be transmitted to others, specific analysis is needed.Generally speaking, nucleic acid clips are not contagious.Some scholars have trained the pharynx and secretions of Fuyang patients, and have not cultivated viruses.
There is also a few cases. The patient originally had a lot of basic diseases, but the symptoms improved and did not fully recover. These patients could not rule out contagious.Overall, I am not too worried about Fuyang patients without contagious.
7. There is no sufficient evidence of the influenza of new crown pneumonia
Will the new crown pneumonia exist for a long time like flu?
He said this is a faction.From now on, there is no sufficient evidence.Unless the virus spreads such a law: its infectious power is still strong, but the mortality rate is getting lower and lower. In this case, there is a possibility of long -term existence.We now need to conduct a long -term observation and master full data and cases in order to draw similar views.In current cases, I don't think this prediction will be reality.
8. Animal dissemination is too early to conclude
Zhong Nanshan said that some animal nucleic acid tests such as dogs, cats, tigers, etc. are caused by pollution or infection, which remains to be observed.Some animals originally had some viruses, not necessarily symptoms, nor did they necessarily be contagious.Now I think that the new coronal virus on these animals can infect people and animals, and can cause disease. The conclusion is too early. Generally speaking, I don't think so.
Nine, there are no special effects, but I found some effective medicines
What is the current progress of drug research and development?
He said that some of the drugs we have tested now, such as chlorine, are definitely effective. We are summing up and may soon be published.There are also some traditional Chinese medicines, such as Lianhua Qing Plague. We not only did a separate experiment, but also found in the P3 laboratory (that is, the three -level laboratory of biological safety protection, editor's note) found that its antiviral effect is not strong, but in terms of anti -inflammatory anti -inflammatory effectThe performance is outstanding, and the results of the experiment will be published soon.In addition, there are Chinese medicine blood. Its main ingredients include safflower, salvia, red peony, etc., which are used for activating blood circulation and removing blood stasis. However, the treatment of severe patients is also effective. We are now summarizing.
Ten, the vaccine will not be listed soon
Zhong Nanshan said that the vaccine is very important to truly end the epidemic. Now countries are developing and developing at the fastest speed.But I don't think the vaccine can be made in three or four months.In addition, based on the experience of fighting SARS, removing the middle host can also block the spread of the epidemic.At present, we don't know what the spread of the new coronal virus is like. It is also important to cut off after making it clear.
Putting all the hopes on the vaccine, other methods are negative.And after the vaccine comes out, it is impossible to be very perfect at once. It is easy to fight, but there is no need to fight all the people.
11. Group immunity is the most negative approach
The most negative approach to the epidemic is the so -called group immunity. This was the idea of more than a hundred years ago. At that time, human beings had no way to allow virus infections. People who survived after the infection naturally obtained antibodies.I do n’t agree with this method to deal with the new crown virus.In the past 100 years, human beings have made great progress. There are many ways to prevent it. There is no need to use natural immunity and group immunity.
12. The most worthwhile experience in China is the experience of execution
Zhong Nanshan said that China's warfare diseases mainly adopted two major measures: first, blocking the upstream areas to block and block and spread; the other is grassroots group defense group treatment, that is, joint defense and joint controlThe core of the prevention and control is also two. The first is to keep the distance and the second is to wear a mask.
Therefore, the most shared experience is execution.The medical level and technical strength of many countries are much higher than that of our country. The reason why it ca n’t be caught in front of the epidemic is because there is no ideological preparation and no decisive measures, which leads to the infection of many first -tier medical staff.It will be easy to get out of control.
