The Covid-19 virus has mutated and has two new features. Zhang Boli made the latest judgment!

In recent days, the Kashgar epidemic in Xinjiang has become the focus of domestic people's attention, and a large number of asymptomatic infections have also attracted the attention of experts. So what changes are currently taking place in the new crown virus? "People's Heroes", academicians of the Chinese Academy of Engineering, Tianjin Traditional Chinese Medicine The president of the University Zhang Boli made the latest judgment. He believes that the virus has mutated and its infectivity has increased but its toxicity has decreased. As there are more and more asymptomatic infections, it will put greater pressure on prevention and control.

Jiang Qingwu, a professor at the School of Public Health of Fudan University, also stated in the CCTV News 1+1 program that, judging from the global epidemic situation, the prevalence and pathogenicity of the disease (new coronary pneumonia) are reducing, and the symptoms are reducing. The proportion of asymptomatic cases is increasing, which is a phenomenon.

 In the face of the constant "evolution" of the new coronavirus, Gao Fu, director of the Chinese Center for Disease Control and Prevention and academician of the Chinese Academy of Sciences, believes that this winter will be a "big test", and the key issue now is vaccines. However, he also said that the new crown vaccine currently faces six unknowns.

Zhang Boli's latest research and judgment:
Viruses are more infectious and less toxic

According to the Wuhan Evening News, on October 26, Zhang Boli, a "people's hero", academician of the Chinese Academy of Engineering, and president of Tianjin University of Traditional Chinese Medicine returned to Wuhan and said that the autumn and winter epidemic prevention should not be relaxed, and the complexity of the new crown pneumonia epidemic must be fully realized.

On the one hand, we have a lot of experience in dealing with the epidemic. For example, in the prevention and control of the new outbreak in Beijing, we quickly tracked the source of infection, implemented precise prevention and control, and implemented integrated traditional Chinese and Western medicine treatment for diagnosed patients; Dalian quickly screened and made more precise deployment. Good; the census of more than 10 million people in Qingdao was completed in five days, reflecting the improvement in testing capabilities. Judging from the treatment of patients, the reduction of severe illness and lower mortality means that we have a better understanding of the disease.

 On the other hand, although the domestic epidemic is mainly spread at multiple points, it is necessary to be alert to the superimposed risks of new coronary pneumonia and influenza. In addition, the virus has mutated, its infectivity has increased but its toxicity has been weakened, and there are more and more asymptomatic infections, which will put greater pressure on prevention and control.


"From a global perspective, the second wave of epidemics has arrived." Academician Zhang Boli said that the United States has added more than 70,000 cases in a single day, France has added more than 30,000 cases in a single day, and the United Kingdom has added more than 10,000 cases in a single day. The country’s single-day new increase is close to the total number of confirmed patients in China, and the severity of the epidemic has exceeded this spring.

"Our domestic epidemic prevention and control are strong. A large-scale outbreak of new crown pneumonia such as Wuhan will not recur, but small-scale outbreaks and scattered points in individual areas are likely to occur in multiple places." Academician Zhang Boli introduced that autumn and winter have already occurred. At this point, the prevention and control of the epidemic cannot be slackened. At present, two issues should be paid attention to. One is to make full preparations for manpower, materials, and organization and coordination around the small-scale rebound that may occur in autumn and winter; Tracking management.

Jiang Qingwu:

The pathogenicity of new coronary pneumonia is decreasing, and the symptoms are decreasing

In the news 1+1 program on the evening of October 26, Jiang Qingwu, a professor at the School of Public Health of Fudan University, said in an interview with Bai Yansong that the outbreak in Kashgar, Xinjiang has its own particularities. The proportion of asymptomatic infections seems to be higher, which is different from the epidemic situation in my country in the first half of the year. But we are also concerned that this infection mainly occurred in companies, mostly young adults.

The symptoms of new coronary pneumonia are relatively mild among young adults and often go undetected. At present, although the proportion of nucleic acid-positive and asymptomatic infections is relatively high, because this is a special group of people, it is a corporate group, I think this phenomenon can still be accepted, this is a phenomenon.

Jiang Qingwu also said: Judging from the epidemic situation in the world, countries and regions around the world have reported that the epidemic and pathogenicity of the disease (new coronary pneumonia) are decreasing, the symptoms are decreasing, and the proportion of asymptomatic cases is increasing. It is a phenomenon. The reasons need to be studied, investigated and further observed. But this phenomenon exists objectively.

When asked if there are more young adults, the cure rate will increase, Jiang Qingwu said that he can understand it this way. Asymptomatic is also a manifestation of (new coronary pneumonia) symptoms, but the symptoms are very mild and are not detected. If the proportion of asymptomatic increases, it is beneficial to treatment. But being asymptomatic also brings other troubles, because they are a source of infection, and it can also spread the virus. Symptoms are easy to detect and can be managed. If the proportion of asymptomatic is high, it may be more difficult to control the spread of the virus. In theory, it is necessary to manage both asymptomatic and symptomatic in order to stop the spread of the virus.
