On May 16, the press conference on epidemic prevention and control in Shanghai introduced that 15 of the 16 districts in the city have achieved social clearance, the total number of sealed and controlled areas has been reduced to less than 1 million, and the number of new positive infections in the city has been reduced to less than 1000 on May 15. The epidemic has been effectively controlled and phased results have been achieved in prevention and control. Previously, Jilin Changchun and other places cleared high and medium risk areas, and the whole region was a low-risk area. It is not easy to clear the social area or the high and medium risk areas. No matter what happens, we don't know how difficult it is. But anyone who has personally experienced the fight against the epidemic knows how much effort people have made for the arrival of this day. The attitude is firm, the action is rapid, the teeth are firm, and the difficulties are overcome. A simple general expression cannot cover the hardships of the fight against the epidemic. Looking back on the days and nights of fighting bravely, some media disclosed an intriguing detail. Lane 465, Zhenning Road, is one of the 24 key communities in the current round of epidemic in Changning District, Shanghai. At the beginning, due to 21 cases in the community one day, some residents went to the neighborhood committee to pat the table and questioned the neighborhood committee cadres about "inaction every day". With the progress of the work, the staff tried their best to give consideration to accuracy and precision in the strict and fast process of clearing and tackling difficulties, and the citizens were less worried and puzzled. "The residents who came to the neighborhood committee to pat the table at the beginning praised it.". This also shows that the epidemic prevention and control can not be perfunctory at all, but we have to work harder. This is the voice of the people. Nowadays, the epidemic prevention and control in many places have achieved phased results, which shows that the efforts of various departments are worth it. It also shows that our prevention and control policies can stand the test of history, and our prevention and control measures are scientific and effective. In addition to being gratified, there should be no slack. At present, the global epidemic is still at a high level, the virus is still mutating, and there is still great uncertainty about the final trend of the epidemic. It is far from time to relax and rest. At present, the epidemic prevention and control work is in a critical period and arduous stage. Epidemic prevention and control, fight is the way, fight is also the determination and will. Especially in the critical period and hard stage, we should exert ourselves to the greatest extent and fight tenaciously without giving up. Based on the experience of epidemic prevention and control for more than two years, it can be clearly found that getting twice the result with half the effort is completely different from getting twice the result with half the effort. If you bite your teeth and stick to it, you can get twice the result with half the effort through the most difficult moment. On the contrary, if you should work hard and have reservations, if you should bite your teeth and insist on releasing the virus, you will get half the result with half the effort and be passive step by step. What we need is to get twice the result with half the effort, is to give it a go until we win. It is worth mentioning that in the face of the complexity of the epidemic, our playing method is also upgrading. One evidence is that the central government clearly proposed to improve the sensitivity of monitoring and early warning, and establish a "sampling circle" of nucleic acid in big cities for 15 minutes to broaden the scope and channels of monitoring. Nucleic acid detection is getting closer and closer to home, even at home. It is not only convenient for people to detect, but also can make it fast. With the continuous optimization of prevention and control means, we have more and more confidence to deal with the virus. "If you are cautious, there will be no failure." Epidemic prevention and control do not want to take the so-called shortcut, nor do they want to be superficial. A big hole in the tip of a needle can leak out the strong wind of a bucket. Plug loopholes, fill weaknesses, and resolutely build a strong epidemic prevention and control barrier. No matter how strong the wind is, there is no hole to drill. We should have a deep, complete and comprehensive understanding of the principles and policies for epidemic prevention and control determined by the Party Central Committee, unify our thoughts and actions into the decision-making and deployment of the Party Central Committee, and everyone should perform their duties with heart and soul, and pay close attention to all aspects of epidemic prevention and control with the spirit of no wait for time and action against the clock. The effect of prevention and control will be further demonstrated. (Xinhua News Agency)
