On June 30, wuzunyou, chief epidemiologist of the China Center for Disease Control and prevention, released a long article on his personal microblog. The following is the full text:

the Ministry of industry and information technology announced on the afternoon of June 29 that the "asterisk" mark on the communication travel card would be canceled to support the efficient coordination of epidemic prevention and control and economic and social development and facilitate the travel of users. This is another optimization and adjustment of specific measures for the prevention and control of novel coronavirus pneumonia, following the health commission's announcement on the 28th that the isolation time of immigrants and close contacts was shortened from "14+7" to "7+3" days

1. How to understand the adjustment of these prevention and control measures

the introduction of these new measures does not mean the relaxation of the new crown prevention and control measures, nor does it mean the abandonment of the dynamic clearing policy, nor does it mean that China will follow the so-called "lying flat" route of the new crown prevention and control in western countries. China's prevention and control of COVID-19 has not changed its fundamental purpose of ensuring people's life safety and health, and its general strategy of "external prevention input and internal prevention rebound" and the general policy of "dynamic clearing". The relevant national departments adjusted the prevention and control measures to further improve and optimize some specific prevention and control measures according to the new situation of the global COVID-19, the new situation of China's COVID-19 and the prevention and control work. This is in line with the principles of scientific prevention and control, in line with China's national conditions, in line with the actual needs of the current new crown prevention and control, and is a concrete manifestation of the precise implementation of prevention and control strategies and measures

2. Will canceling the "asterisk" mark bring the risk of new crown popularity

the "asterisk" mark on the communication travel card indicates that the smart phone user has visited a city or some cities with medium or high risk areas in the previous 14 days, which does not mean that the user has actually visited these medium or high risk areas. The tag is only used as a travel reminder and is not associated with the user's personal health status

the "asterisk" of the communication travel card has played a certain role in bringing people who may be at risk of infection into the perspective of prevention and control to the greatest extent, especially in the special period of severe and complex epidemic

canceling the "asterisk" mark will not increase the risk of new crown transmission. The "asterisk" only indicates that a person is from a city with high or medium risk areas, and is not directly linked to specific high or medium risk areas, that is, it cannot reflect the actual risk level of the "asterisk" reporter. With the continuous improvement of scientific prevention and control and precise measures, the division of high-risk areas / medium risk areas and the prevention and control management requirements are more refined and precise. The "asterisk" mark on the communication travel card is difficult to play a role in the specific implementation of the new prevention and control strategy

3. Does canceling the "asterisk" mean that the person being isolated should cancel the isolation

"asterisk" marking and isolation are two different concepts, and there is no necessary connection between them. Isolation of domestic personnel is mainly a preventive measure for close contacts to prevent the possible spread of the epidemic. The cancellation of the "asterisk" mark has nothing to do with whether the close contacts being isolated terminate the isolation measures

in some places at the grass-roots level, the prevention and control measures may be increased layer by layer, and those marked with an asterisk have also taken isolation measures. This approach is wrong and does not conform to the spirit of scientific prevention and control and precise policy implementation. If there is such a situation, such erroneous practices should also be terminated after the "asterisk" mark is cancelled

4. What positive impact will the cancellation of the "asterisk" have on the society and the people

the cancellation of the "asterisk" mark is a concrete manifestation of the implementation of the Party Central Committee's clear requirements of "epidemic prevention, economic stability and safe development", which is conducive to the real integration of epidemic prevention and control and economic and social development

canceling the "asterisk" mark will play a positive role in promoting the flow of people and invigorating economic development

canceling the "asterisk" mark is conducive to the implementation of the main measures of the prevention and control program for novel coronavirus pneumonia (Ninth Edition)

the cancellation of the "asterisk" mark will no longer provide any excuse for the possible excessive epidemic prevention, or even the "overriding" practice of epidemic prevention
