First of all, at present, the prevention and control of epidemic situation at home and abroad is very complicated. China's policy is to insist on dynamic zero clearing, aiming at protecting people's life safety and health to the maximum extent and minimizing the impact of epidemic situation on economic and social development, especially at present, the epidemic situation in China is complex, with the characteristics of sporadic, local outbreak, rapid spread and strong concealment. Therefore, it is also an important decision of our country to insist on dynamic zero clearing.
Secondly, Shanghai, a big city with a population of more than 20 million, is one of the leading cities in China's economic and industrial upgrading. Therefore, the social liquidation in Shanghai 15 District has played an important role in the local economic development. The epidemic prevention work in Shanghai is mainly reflected in this aspect. In the closed control area, the residential area is fully managed, and all personnel are kept indoors except vehicles and personnel. Contactless delivery of take-out and express delivery necessary for basic life can not only meet the living requirements of the community, but also effectively block the spread of the virus, thus reducing the possibility of infection.
Thirdly, in the closed control area, all enterprises implement closed production or home office, which can not only reduce the infection caused by the flow of people, but also promote the economy and protect people's livelihood.
Finally, for Shanghai's epidemic prevention policy, we need to learn from it by insisting on dynamic zero clearing. When a case is found, it is necessary to take the form of sealed control and conduct multiple rounds of nucleic acid testing for all people who may be infected within the jurisdiction. The purpose of multiple rounds of nucleic acid testing is to screen out patients who may be infected as soon as possible, so as to block the spread of the virus at the source. For the daily necessities that citizens need, epidemic prevention personnel should distribute them uniformly, so as to cut off the situation that may occur due to the flow of people.
