In the three years since the emergence of COVID-19, the relevant departments have brought it into the scope of Class B and Class A management, and at the same time, it has opened a long road to fight the epidemic. In order to continuously improve the scientificity and accuracy of epidemic prevention management, all localities have successively adjusted it to B and B to coordinate with prevention and control? New ten? At the same time, it also minimized the impact of the epidemic on people's lives and production. This management mode shows that the virus is transforming from pneumonia to respiratory infection, and the attack on human body is gradually weakening. Relevant departments will adjust the management category of infectious diseases at an appropriate time.

Isolation management measures are different.

Recently, with the transfer of COVID-19 from Class B to Class B, experts said that it was originally classified as Class B because it attacked the human body violently in the early stage of the epidemic and needed to be controlled in this way. However, the current adjustment is that the changing trend of the virus has stabilized, so it will return to the normal management stage of infectious diseases. The great difference of management is that it can return to the routine management state of health system, which can not only isolate the close contacts of patients according to law, but also disinfect and pollute the environment and protect the vulnerable groups.

Are there differences in social prevention and control management?

According to the law of infectious diseases, infectious diseases are classified into three categories: A, B and C. Although they have different degrees of damage to human health, different societies adopt different prevention and control measures. For class a, compulsory social control is needed; For class B, it is necessary to manage each case well and do not need to take large-scale social prevention and control management; For Class C, it is only necessary to monitor and take effective preventive measures. On the whole, with the change of virus infectivity from heavy to light, it will eventually be adjusted to Class C and Class C in the future, and it will be graded according to the epidemic situation and the degree of harm, so that it will be gradually improved in the direction of precision science.
