Since the beginning of this year, Omicron virus has ravaged the world, and the number of people infected with Covid-19 has surged, and the epidemic situation in some parts of China has also rebounded significantly. Especially in recent years, the prevention and control of epidemic situation in Shanghai and Jilin have been under great pressure. The more critical this moment is, the more we must strengthen our confidence, maintain our strength, adhere to the general strategy of "external defense input, internal defense rebound" and the general policy of "dynamic zero clearing", and take decisive measures to curb the spread of the epidemic as soon as possible.
"Dynamic zero clearing" is a prevention and control practice put forward on the basis of summing up the experience and lessons in the past two years, which has been repeatedly tested by practice. Its goal is to control the epidemic in the shortest time with the lowest social cost, reduce the impact of the epidemic on economic and social development and people’s production and life, and ensure sustained, healthy and stable economic and social development with good prevention and control results. This not only respects scientific laws, but also conforms to China’s national conditions.
The core of "dynamic zero clearing" is rapid response and accurate prevention and control. This requires us to improve the ability of epidemic prevention and early detection on the basis of grasping early, grasping small and grasping the foundation. In particular, Omicron mutant has the characteristics of fast spread, high proportion of recessive infection and mild cases, and more asymptomatic and mild infections, which makes it more difficult to find cases and puts forward higher standards for epidemic prevention and control. The increasing number of confirmed cases requires us to make all prevention and control measures faster, more accurate and more detailed, strive to race against the virus, and achieve the maximum prevention and control effect with the least cost.
Efficient and orderly nucleic acid detection, scientific and accurate flow tracing, classified and graded prevention and control management, and systematic operation of joint prevention and control & HELIP; … Over the past two years, China has formed a set of scientific measures and epidemic prevention skills to fight the epidemic, and has the ability and confidence to achieve "dynamic zero clearing". Anti-epidemic practice has fully proved that "dynamic zero clearing" is the best choice based on the current epidemic situation in China at this stage, and it is still the most economical and effective epidemic prevention and control strategy to achieve "dynamic zero clearing" in a short time.
To implement the "dynamic zero clearing" strategy, we should continue to uphold the scientific spirit, respect the law, and strive to work together at both ends. At the front end, efforts should be made to improve the speed of epidemic monitoring, early warning and emergency response, continue to increase the detection of nucleic acids and antibodies, and maintain the requirements of "double detection" and isolation. In particular, we should study the work of providing rapid detection reagents for key cities and key populations free of charge, and put them out together to minimize and control the risk of epidemic spread; At the back end, we will further improve the vaccination rate of domestic vaccines, especially the vaccination rate of the elderly, increase the research and prevention of virus variation, speed up scientific and technological research on new generation vaccines, rapid detection reagents and drugs, and provide strong support for "internal defense rebound".
Facing the ups and downs of the epidemic in the century, dealing with the epidemic scientifically, quickly and effectively is a "big test" for our prevention and control level and governance ability. All localities and departments should unswervingly adhere to the general policy of "dynamic zero clearing", strive to improve the scientific and accurate level of prevention and control, adhere to strict and practical measures to prevent and control the epidemic, and win the tough battle of this epidemic prevention and control as soon as possible.
