As a result, with the removal of street Wells, cholera was miraculously stopped. It was the cholera that prompted London to decide to build a complete urban underground sewer system and the Thames Embankment causeway project,

which also made London a truly modern city. The whole process demonstrates the power of science and fully proves that the most powerful weapon for human beings to fight against disease is science and technology. Throughout history, in the struggle between human beings and epidemics, the passive situation was changed because of the "war" of science and technology.

When it comes to scientific epidemic prevention, it is safe to say that China has a proud record. Since 2020, the COVID-19 epidemic has broken out in some cities across the country, and the clouds have darkened for a time. In the face of the epidemic,

under the strong leadership of the CPC Central Committee, people across the country have worked together and responded calmly. After more than a year of heroic struggle, we have a clearer understanding of the novel coronavirus,

and all localities have accumulated rich experience and mature measures. In particular, Shanghai and other cities with outstanding epidemic prevention and control results have creatively combined national prevention and control strategies and measures with local conditions,

and have explored a series of scientific response paths and measures, and summarized a set of scientific and effective experience and practices, focusing on key tasks and links such as source prevention and control,

patient treatment, material support, and emergency response. It has strong guidance, pertinence and operability for epidemic prevention and control. "Stones from other mountains, can attack jade", at present, in the face of the epidemic prevention and control situation in Zhangye,

we most need to learn and use the mature experience they have obtained, to science and methods, and in practice combined with the actual sum up and improve, will certainly play a "four or two" role.

Learning from the experience of Shanghai, the focus should be on learning their management system, accurate flow adjustment, community prevention and control. In view of the current situation in our city, it is important to learn methods,

learn how to use them well, how to maintain the sensitivity of "should be checked" and fever outpatient sentinel, how to achieve early detection, and the advanced practice of controlling the epidemic at the point and not spreading;

They have always maintained the daily operation of the emergency command system, kept the backbone of prevention and control relatively stable, and advanced practices in key links such as the level command mechanism,

mobile deployment teams, and the construction of isolation points; They have advanced practices to grasp the important "golden 24 hours" window period after the discovery of the epidemic,

namely: On-site epidemiological investigation should be completed within 2 hours to the scene, complete the investigation of core epidemiological information within 4 hours, complete the investigation of the workplace,

residence place, movement track, family member relationship and other specific circumstances of the case within 24 hours, and report the investigation progress every hour in the first 24 hours of epidemic treatment.

It is necessary to control the flow while regulating the flow, timely screening of at-risk populations, implementing measures such as code assignment, nucleic acid testing, and isolation management,

and quickly taking control measures in at-risk areas. At the same time, the scope of close contact tracking should be appropriately expanded and management strengthened.

Learning is to improve, we must draw inferences from one another. We should make good reference to the mature experience of advanced regions to find out what problems and weaknesses exist in the hardware,

mechanism and software of epidemic prevention and control in their own regions and departments. We need to see if all our anti-epidemic measures have been fully implemented and whether they can achieve the expected results.

Then, for the key links such as flow investigation, centralized isolation, nucleic acid screening, community control and mass life service guarantee, we sorted out problems one by one, made a list,

came up with precise and practical measures, established rectification and implementation accounts, listed supervision and implementation of sales, and ensured high-quality results with high-quality execution. Only in this way can the overall prevention and control campaign live up to the organization's trust and the people's expectations.

Science is the "cure" to dispel the "epidemic". Whether it is the effective response of the prevention and control command system, or the accurate and accurate monitoring, investigation and early warning of the epidemic;

Whether it is the better use of technical means in epidemic prevention and control, or the public's scientific understanding of the virus and prevention and control, only by adhering to a scientific and systematic prevention and control strategy can we effectively defeat the virus and earnestly strengthen the confidence and courage of the whole society to fight the epidemic together.
