China's recent epidemic prevention and control measures have shifted, and local prevention and control gradually loosen.According to Chinese infectious disease experts, according to the characteristics of the existing coronary virus, it is not appropriate to continue the Class A model that has been managed according to class A infectious disease level. It is possible to return to the management of Class B or even relegated to Class C. It will become possible.
In response to the characteristics of super propagation and strong pathogenesis of crown diseases, Chinese officials include it into class B infectious diseases in January 2020, but adopt the management measures for class A infectious diseases.
According to the First Financial Report, whether the epidemic characteristics presented by the current coronary virus meet the conditions for disconnecting the management of Class A and whether it is suitable for returning to the management of infectious diseases of Class B. A infectious disease expert said that"The main basis of infectious disease management model comes from the infectious and pathogenic force of infectious diseases." For infectious diseases with strong pathogenicity, high mortality, and strong infectious diseases, generally classified as class A or Class B managementThe control measures are generally adopted for mandatory isolation, epidemic blocking, etc.
For the high incidence and cause high disease mortality, but the ability to spread is limited, it will cause some harm to the society, and it will be classified as a class B;, Generally classified as Class C.
But with the continuous mutation of the virus, the clinical characteristics of Omiko's mutant strains that are currently popular in the world have gradually been recognized.Enhanced, but its disease and mortality rate decreased.Therefore, the management level must be re -considered.
From the perspective of the current epidemic disease characteristics of the coronary virus, the above -mentioned infectious disease experts say that many places show that more than 95%of the infected people are asymptomatic and milder, and the mortality rate is very low.In the case, it is obviously inconsistent with science according to Class A management. Therefore, the return of crown disease to Class B management or even downgrade into Class C will be possible.
In the current round of epidemic in China, the proportion of asymptomatic infections remains high.Zhang Yi, deputy director and press spokesman of the Guangzhou Municipal Health and Health Commission, reported at the press conference on December 2 that this round of the epidemic reported 162,700 local infected people in Guangzhou, and the total number of infected people accounted for about 90 % of the infected people.There are only four cases of critical illness, and there are no cases of death.
Researcher Chang Zhaorui, a researcher at the China Centers for Disease Control and Prevention, also said at a press conference on November 28 that foreign studies have shown that the proportion of severe and death caused by Omikon's mutation is significantly lower than before.Primitive plant and concern.
The above -mentioned infectious disease experts said, "Obviously, the current pathogenic force of popular strains is relatively weak. Under the condition of completing basic immunity across the country, it is not a problem according to the management of Class B.Management can also provide a certain legal basis for further optimization of prevention and control measures in the future, so that there are laws to rely on. "
Deputy Director of the Infement and Liver Disease Center of Southern Medical University, deputy director of the Department of Infectious Department of Infectious and Liver Disease CenterPeng Yan, the chief physician, said that the listing of crown diseases as Grade A in 2020 was not enough to consider the disease itself and the virus, and the mortality rate at that time was very high.Although the Omeck Rongfei strains today, although the infectious strength becomes stronger, the toxic force becomes weakened, and the mortality rate has been greatly reduced.From the characteristics of virus and disease, the current model of continuing Grade A management is not suitable.
According to the provisions of the infectious disease prevention and control law, China divides the infectious disease into class A, Class B, and C.Class A infectious diseases include cholera and plague.
Category B includes 25 types of infectious atypical pneumonia (Shas), disease of love, viral hepatitis, spinal ash, and high pathogenic avian influenza; Class C includes epidemic cold, 10 kinds of popular mumps, rubella and other 10 species.
