The novel coronavirus pneumonia prevention and control work office of Shanghai led the study to determine the location of the confirmed cases as a risk area and the risk level of other regions remained unchanged, according to the Red Star news report. It is reported that the medium risk area is actually a milk tea shop, with an area of only more than 20 square meters. Many netizens said that this is the "minimum risk area" in the world. The reason for this division is not a trifle, but a prudent decision made by the relevant local departments after scientific analysis and judgment. Shanghai Health Commission said at the press conference that the five infected persons reported in Shanghai were associated with a asymptomatic infected person imported from abroad reported in Shanghai on January 11, belonging to the same transmission chain, and were found in routine nucleic acid screening and testing during isolation and control. At the same time, all the close contacts were negative, with a total of 2830 people, which have been isolated and controlled. All these information indicates that the risk of 5 local COVID-19 infected people in Shanghai is generally controllable. The milk tea shop is a "medium risk area" with the smallest floor area since the outbreak of the epidemic. Therefore, the local epidemic prevention attitude and practice have won many praise. This also shows that through scientific analysis, judgment and accurate policy implementation, the scope of influence can be reduced as much as possible and the inconvenience to the people can be minimized. This actually reflects the local confidence and confidence in their epidemic prevention ability and measures, as well as a sense of responsibility. War and epidemic is a protracted war, and scientific and accurate epidemic prevention is a consensus. Since the novel coronavirus pneumonia outbreak, some places obvious to people in the field of big data flow adjustment and community prevention and control, but there are also some places that have been exerting too much force. Some inappropriate measures have been taken. Some places even appear the extreme practices of "one person positive city" such as "control and control". These seemingly "strong" and actually "one size fits all" measures are actually adding chaos and blockage to the war epidemic. In the context of normalization of epidemic prevention and control, the more accurate the prevention and control measures, the smaller the adverse effects and the more efficient the results. More than two months ago, Shanghai Disney carried out nucleic acid detection under the night sky with fireworks in full bloom. The tense, orderly but warm picture also received people's praise. A common signal from similar measures is that epidemic prevention is very important and people's livelihood should be ensured. If we only consider preventing the spread of the epidemic, many places can "rather waste than indulge". However, from the perspective of social development and people's interests, local governments should not only consider a single goal in decision-making, but should take into account multiple goals such as epidemic prevention, people's livelihood and economic development. People oriented and accurate epidemic prevention is of guiding significance for the normalization of epidemic prevention and control in all regions. The smaller the scope of the risk area, the smaller the impact on the normal operation of the whole city and the daily life of surrounding residents. The war epidemic measures in some places are often "amazing". In fact, there is no secret. It is just that we have made great efforts in precise prevention and control. This is not only a matter of material basis and technical conditions, but also a comprehensive test of emergency mechanism and management wisdom. The suspension of milk tea shops is a small step and a big step in the accurate prevention and control of the epidemic in a big city. This practice and its epidemic prevention concept and thinking are worth learning from in more places. Of course, epidemic prevention and control also needs to adapt to local conditions. It is impossible for any place to simply copy the "operation" of a place. However, it is clear that as long as we uphold the people-oriented concept, make full use of modern scientific and technological means to carry out more scientific and accurate prevention and control, it is an appropriate epidemic prevention policy.
