Zhong Nanshan talks about the prevention and control of the epidemic in Hong Kong: there has not been a geometric increase, and the national nucleic acid screening should be carried out as soon as possible

　　Today (July 29), in Guangzhou, Guangdong, Zhong Nanshan, an academician of the Chinese Academy of Engineering, answered questions from reporters on the recent development of the epidemic in Hong Kong and prevention and control measures. He said that based on the current daily data on new cases in Hong Kong, the Hong Kong epidemic In the process of development, community infection has occurred, but there has not been an exponential increase, so the key depends on the next prevention and control situation.

Zhong Nanshan: The current epidemic in Hong Kong is still developing and community infection has occurred

Zhong Nanshan, academician of the Chinese Academy of Engineering: The prevalence rate in Hong Kong is about 37 per 100,000, and the mortality rate is 0.7 per 100,000, so this data is not too much.

　　The epidemic situation in Hong Kong is still developing. At that time in February and April, we felt that Hong Kong was doing very well and doing it very successfully. From late June to July 8, this time is less than 30 (daily). From July 8th to 18th, the number of confirmed cases was a little more, usually not more than 60. After July 18, there are more than 100 (daily new additions) in 10 days except for a few days, and the highest is more than 140. So it looks like the epidemic is developing. What does it mean? The disease has spread to the community. That is to say, some sources of external input, etc., were later passed on to others and infected in the community; if the community cannot track it, it will be passed on to the second or third generation...

　　But its growth is not exactly like a chain reaction model, that is to say, the growth of geometric series, its growth is also like the increase of the series counted on a plane, from more than 20 to more than 30, More than 60, now to more than 100. It shows that government intervention and social intervention still played a big role.

　　It should be said that the epidemic is now in Hong Kong and has spread in the community. But it is not like the exponential growth of the western countries with geometric progression or chain reaction, which shows that in a certain sense, it is now in a tug of war . The key to the tug of war is to look at the prevention and control situation.

Zhong Nanshan: Hong Kong should carry out universal nucleic acid screening to further implement prevention and control

　　When talking about the prevention and control measures currently adopted in Hong Kong, Academician Zhong Nanshan said that although the current prevention and control measures have produced a certain degree of intervention, they should be further strengthened and implemented, such as restricting dine-in and gathering activities, and suggested Carry out universal nucleic acid screening in Hong Kong.

Zhong Nanshan, academician of the Chinese Academy of Engineering: I think Hong Kong is still grasping two very main problems. One is in the Huangdaxian District of Ciyun Mountain, which is a gathering place. Nucleic acid testing for the entire region has been adopted; the other measure is that once If they are found to be positive, they must be isolated regardless of symptoms.

　　If it is the Mainland, the measures taken will be stronger than Hong Kong. However, Hong Kong has its own characteristics. The place is too small and the population density is very high. If the same method is adopted, it will have a certain impact on economic development and other aspects. So all have their own methods: one is to strengthen the examination and find asymptomatic patients. Because symptoms are a subjective factor, asymptomatic is actually part of the incubation period, especially in the first 5 days and 5 days after the onset of symptoms, the most infectious. So I think the whole of Hong Kong is only 78 million, at best 10 million, it should be checked all over, and after the check, they should be isolated as soon as possible.

　　As far as I know, the people of Hong Kong go for testing voluntarily, but my opinion is that if the disease still develops, it should be administratively required that everyone be tested. In addition, it is very necessary to increase the testing materials, testing personnel, and strengthen the construction of simple hospitals.

　　Now there is a big advantage that the government has proposed that dine-in is not allowed. Because ordinary families in Hong Kong cook very little for themselves, and everyone eats outside, restaurants are a very important source of infection. It is important not to allow dine-in.

Zhong Nanshan: Actively support and resolutely crack down on illegal assemblies in terms of detection and manpower

　　Regarding how to provide support for the prevention and control of the epidemic in Hong Kong, Academician Zhong Nanshan said that support should be provided in terms of testing reagents and manpower. For Hong Kong, the main problem is not medical problems, but public health prevention and control problems.

Zhong Nanshan, academician of the Chinese Academy of Engineering: I think we have always been active in supporting any place, so Hong Kong is even more so, because it is my family, of course we should actively support it. For example, support for reagents, support for testing personnel, and manual support for the establishment of square cabin hospitals. Because Hong Kong's medical force is still good, the case fatality rate is 0.7 per 100,000, which is good in the world.

The main problem in Hong Kong is not medical problems, but prevention and control problems. It is still very important for the prevention and control of public health to be done well. What I want to remind is that Hong Kong has also experienced some very bad phenomena with the recent surge in the number of infected people. Hong Kong must resolutely crack down on those who deliberately come out to make troubles and engage in gatherings during difficult times and during the extraordinary period of the epidemic (prevention and control), because this involves tens of millions of lives in Hong Kong.

Zhong Nanshan: It is recommended that Hong Kong conduct free nucleic acid testing to strengthen exchanges with the mainland

　　Regarding how Hong Kong should take measures to further limit the spread of the epidemic, Academician Zhong Nanshan put forward several suggestions. First, it is recommended to conduct national nucleic acid testing, support free nucleic acid testing, and strengthen exchanges between Hong Kong and the mainland in prevention, control and medical treatment.

Zhong Nanshan, academician of the Chinese Academy of Engineering: There are several suggestions. One is to strengthen prevention and control measures. I very much agree that there is a national nucleic acid check-up in Hong Kong. It is not cheap in private hospitals. I am afraid that from the government's point of view, it should be free (nucleic acid test). I believe this has already been done.

　　Second, I hope that Hong Kong's prevention and control and medical services will have more exchanges with mainland China. Our attitude towards new coronary pneumonia and prevention and control are completely the same. Once Hong Kong has demand in what areas, it will definitely go all out without hesitation. We should have more exchanges in prevention and treatment.

　　Finally, the main contradiction now lies in the upstream, preventing him from infection, so communication in public health and prevention and control is very important. After all, cases appeared earlier in mainland China, and there are many experiences and lessons. If we communicate with each other, it will definitely help improve prevention and control.
