National Bureau of Disease Control and Prevention： ＂Dynamic zero clearing＂ is to improve the ability of epidemic prevention and early detection based on grasping early and grasping small.

　　BEIJING, Sept. 7 (Xinhua)-On the afternoon of the 7th, the Propaganda Department of the CPC Central Committee held a press conference on the development achievements of health care since the 18th CPC National Congress. Chang Jile, deputy director of the National Bureau of Disease Control and Prevention, said at the meeting that the policy of "dynamic zero clearing" is to focus on grasping the foundation early, improve the ability of epidemic prevention and early detection, find infected people and epidemics quickly and early, and put them out together at the lowest social cost to control the epidemic in the shortest time.

　　"The cost of evaluating epidemic prevention and control policies and measures should be calculated in the general ledger. The whole country should be regarded as a whole, and it should be counted as a big economic account, a big social account, a big livelihood account and a big health account." Chang Jile pointed out that the concept of prevention and control in China has always been to uphold the people first and life first. The purpose of prevention and control measures is to minimize the impact of the epidemic on the economy and society. Of course, these measures will inevitably cause some inconvenience to normal production and life, but they adhere to the "national chess game" and take local and strict prevention and control measures in areas with epidemics, ensuring the normal production and life of most areas and people in the country and ensuring the stability of the supply chain. If the general ledger is calculated, China’s prevention and control measures are the most economical and the effect is the best.

　　Chang Jile said that we are facing a once-in-a-century epidemic of infectious diseases. At present, the global epidemic situation is still at a high level, the virus is still mutating, the understanding of Covid-19 and diseases is still in the process of deepening, there are still many uncertainties, and the risks and threats brought by the epidemic still exist. We must handle the relationship between short-term and long-term, local and overall with unswerving strategic determination, constantly optimize prevention and control policies and measures according to time, place and situation, and efficiently coordinate epidemic prevention and control with economic and social development. This is not only the basic requirement of adhering to the scientific spirit and attitude, but also the realistic choice of following scientific laws.
