Due to the coordination of flow survey, Shanghai Disneyland Resort temporarily notified the park to close on October 31, and immediately carried out nucleic acid testing for tourists in the park. During this period, Halloween Parade and fireworks show were carried out in the park as usual, and more than 30000 people, nearly 1000 items and environmental samples were screened that night. Under the gorgeous fireworks, the "famous scene" of efficient and orderly nucleic acid detection in Shanghai brushed the screen network for a time, which attracted praise from netizens. Dr. Zhang Wenhong also said in his microblog: "thanks for the immortal fireworks, let's see mankind's calm and confidence in the future in front of the disaster." In response to this incident, Shanghai completed the nucleic acid screening of tens of thousands of people in a relatively short time, and also did a good job in the transportation, refund and exchange of stranded tourists. However, the lives of most citizens were not disturbed, and a series of accurate, rigorous and humanized prevention and control measures made people feel warm. Why does Shanghai have the confidence to take it easy? "Normalization of epidemic situation and standardization of epidemic treatment" -- Dr. Zhang Wenhong gave the answer in his microblog. The so-called standardization is to formulate and implement relevant standards for something in order to obtain the best order and social benefits. Based on the profound summary of the experience of epidemic prevention and control in Shanghai, it is an important reason to achieve accurate prevention and control by standardizing the work of epidemic disposal and completing the institutionalized and standardized treatment process. In the face of complex COVID-19, we are calling for scientific and epidemic prevention to develop precise prevention and control, optimize regional governance capability and public health system. The whole society has made great progress in handling the epidemic situation. At the same time, we have to admit that there is still a big gap between different regions in the scientific and accurate degree of epidemic prevention and control. After the outbreak, how wide is the scope of prevention and control? How to define home isolation and centralized isolation? Can I take a pet for isolation? On many issues, all localities have no reference standards. Governance is not accurate, and it is the masses who pay the bill. Therefore, the standardized disposal process is expected to become an excellent tool for scientific epidemic prevention and accurate prevention and control. First, the essence of standardization is simplification. Based on the past successful experience in epidemic prevention and control, the formulation and implementation of epidemic treatment standards is conducive to local reference, replication and promotion, which can save social costs to the greatest extent, greatly improve the efficiency of epidemic prevention, respond to the public's right to know and reduce the occurrence of rights wrangling. Secondly, standardization is also one of the important methods for the modernization of social governance system. At present, the normalization of epidemic situation is an indisputable fact. If we formulate epidemic prevention and control measures with more systematic concepts, scientific methods and standardized means, we can better coordinate epidemic prevention and control and economic development, coordinate people's life safety and production and life, and get more understanding and support.
