Eight ask Zhong Nanshan: novel coronavirus pneumonia situation?

What is the novel coronavirus transmission route? What's the difference with SARS? In response to the novel coronavirus infection pneumonia situation, academician Zhong Nanshan, head of the National Health Protection Committee's senior expert group, interviewed Bai Yansong, and responded to the public's concerns Zhong Nanshan: the novel coronavirus now appears not only different from SARS, but also different from the Middle East respiratory syndrome, which is a completely different virus The infection of the novel coronavirus has just started and is climbing, so it is less infectious than SARS, and its virulence is not so great I think there is a difference between the severity and transmission of the disease Zhong Nanshan: there are two factors Once a novel coronavirus infection is present, we have accumulated some experience The treatment is much better than before On the other hand, because the disease is at an initial stage, the current case fatality rate is not comprehensive, I'm afraid it depends on the development of the disease On this issue, we should be vigilant The current situation does not represent the whole picture of the disease, because the disease is just beginning and in a climbing stage Zhong Nanshan: there are two reasons For new diseases, reagents are different from place to place It needs an authoritative unit to further confirm, and it will take some time Another factor, these days, the situation is different, in a sense, the disease in the local development is relatively fast Zhong Nanshan: any acute infectious disease is not good news! In a sense, from the perspective of epidemiology, it is not only concentrated in Wuhan, but also in two regions, which account for about 45% These two areas have one feature, a relatively large so-called seafood market Actually, it's not seafood, but game, wild animals According to the preliminary epidemiological analysis in various aspects, it is actually transmitted to human beings through wild animals, which is quite possible But now there is still the phenomenon of human to human transmission, which is the time for us to be more vigilant Zhong Nanshan: according to the current data, it must have been passed on In Wuhan, novel coronavirus was found in Guangdong, but two patients in Wuhan did not go to Wuhan Zhong Nanshan: now I don't know enough about it We can only in principle, first, it is a new type of coronavirus Some of the symptoms it causes are similar to those of SARS before Second, it is not clear what kind of animal it originated from Only from all aspects of epidemiological investigation, it is more likely to come from a wild animal, such as bamboo rat, badger and so on Zhong Nanshan: it's contagious Now it's human to human At the same time, the medical staff are also contagious We should be more vigilant The key points are: one is prevention Don't go to Wuhan without special circumstances, which is very important If you feel sick or have a cold, you should go to the local fever clinic and check if necessary If you are uncomfortable, you need to wear a mask It is still useful to wear a mask In fact, you don't have to wear N95 Because these viruses don't exist alone, they often exist in droplets General surgical masks can block most of them Wearing masks is still useful.
