What is the difference between dynamic clearing and zero infection
According to CCTV on April 19, The Joint Prevention and Control Mechanism of the State Council held a press conference in Beijing to introduce the situation regarding epidemic prevention and control in a strict and practical manner.
Mi Feng, spokesperson of the National Health and Health Commission and deputy director of the Publicity Department, said that we must continue to adhere to external defense against imports and internal defense against rebound, adhere to scientific precision, dynamic clearing, and do not hesitate or waver. We will pay close attention to various measures for epidemic prevention and control, consolidate responsibilities at every level, and promote the close connection of testing, transport, and admission, so as to achieve the goal of social clearance as soon as possible. It is necessary to effectively ensure the supply of medical drugs and food, and respond to and solve the urgent needs of the masses in a timely manner.
What is the difference between dynamic zeroing and zero infection? Why choose dynamic clearing at this stage? Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said that there is an essential difference between dynamic clearing and zero infection. Dynamic clearing refers to the discovery and elimination of the new crown epidemic that occurs, so as not to allow the new crown virus to spread in the place where the epidemic occurred, but also to prevent the virus from spreading to other areas.
In other words, it is not required that the whole country be free of new crown infections at a certain time, but for each outbreak that occurs, it is required to be brought under control in a relatively short period of time.
After a person is infected with the new coronavirus, detoxification occurs after 1-2 days of viral replication growth (that is, the nucleic acid test is positive), and the detoxification continues for about 7-12 days. The new coronavirus can only survive if it continues to spread among humans. If the infected person cannot spread the virus to other people beyond the maximum detoxification time, the virus will be eliminated by the body’s immune function. Find out all the infected people in an epidemic, take physical isolation to prevent their spread, and maintain a maximum detoxification time not to infect others, and the virus will be eliminated at the location of the epidemic. Therefore, the earlier the epidemic is discovered and the smaller the scale of the epidemic, the easier it is to achieve dynamic clearing.
