Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital, China National Infectious Diseases Medical Center and Fudan University, said that providing full protection for fragile people is the key point for getting out of the outbreak of the crown disease.
According to the surging news report, at the 2022 Medical Virus Conference held on Saturday (December 3), Zhang Wenhong said that with the new changes in the virus, some new new changes have currently appeared, and some new new changes have currently appeared. At presentThe clinical characteristics are gradually changing.
Zhang Wenhong believes that the direction of the evolution of the virus is to break through the pressure brought by the human body's immunity, so it will change towards the increasing direction of spreading, so that the genes can be passed out to achieve realizing the genetic and realize the realizationPropaganda, but by vaccination or repeated infection, it will continue to put pressure on the virus. This will make each virus mutation very difficult, and the amount of mutation is also decreasing. Each mutation is like jumping out of the gap.The vaccination and treatment methods, especially the vaccine vaccination, have made the restrictions of the virus more and larger.
Zhang Wenhong said that the research data published by his team showed that the protection of vaccines on the protection of the elderly was significant, and the gravity rate of elderly crown disease was relatively high.The ability is greatly improved.In addition to elderly patients, dialysis patients and heart disease patients are also crowded patients with crown disease. Metabolic diseases, chronic kidney disease, long -term bed, and tumor patients are the "vulnerability" factor of severe critical patients.
"In the fragile crowd, 10%were severe due to crown disease, and 90%were severe diseases. The two severe illnesses constituted a spectrum of crown disease. This allows our future treatment ideasIt becomes clearer and clearer. If there is a certain degree of medical resource crowding, the mortality rate caused by Omikon will increase, especially the disease mortality rate of the elderly will increase. ThereforeImportant, "Zhang Wenhong said.
Sun Chunlan, Vice Premier of the State Council of the State Council of China, held a symposium to hear the opinions and suggestions of prevention and control, and repeatedly mentioned "walking a small step."In this regard, Zhang Wenhong believes that "taking a small step" means to provide sufficient protection for the fragile crowd, and Singapore will be very cautious to protect the protection of the fragile crowd.The aspects are very sufficient, reaching more than 90%. The 7 -day mortality rate is now very low and low. The proportion of people who have been vaccinated is only 0.02%.Therefore, the key point of getting out of the epidemic is the protection of fragile people, and immune protection is a major focus.
But Zhang Wenhong also mentioned the problem of immune escape, that is, infection after the vaccine.Regarding how to improve the effectiveness of the vaccine, Zhang Wenhong suggested that when the third pins are inoculated, they choose to inoculate.In addition, he also called on the fourth pins vaccination in the future.
He said that in the end, whether he can establish a crowd immune barrier through immune vaccination. It has already shown this feature. From the perspective of the Shanghai epidemic experience, the vaccine vaccination and repeated natural infections will continue.Provide people with immune barrier and immune pressure, which will constantly reduce the toxicity of the virus.
Zhang Wenhong finally pointed out that there was a saying in the field of illness and control in the past that it was to "run with the virus and follow the virus", which is a competition between humans to eliminate virus and virus transmission.But today, through vaccination and drug treatment, it has entered the stage of domestication and control of virus.Relying on scientific and technological capabilities, in the future, the control of virus popularity may not be the clear zero of nucleic acids, but to reduce the symptoms or intensive ratio to a very low level.It is believed that the domestication of human coronal virus in the future can be realized.
