(Fighting against New Coronary Pneumonia) "Early detection" is the key to controlling the epidemic, and China emphasizes preparing for a long-term fight against the new crown

　　China News Agency, Beijing, April 19 (Reporter Ying Ni) Is dynamic clearing to achieve zero infection?

What is the key to controlling the new crown epidemic?

Will the pathogenicity of the new coronavirus weaken in the future?

How to deal with the cross-provincial logistics bottleneck caused by the epidemic?

How to solve the "last mile" and "last 100 meters" delivery problem?

On the 19th, the State Council's joint prevention and control mechanism press conference focused on answering these questions.

There is an essential difference between "dynamic clearing" and "zero infection"

　　Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, pointed out at the press conference that there is an essential difference between dynamic clearing and zero infection.

Dynamic clearing refers to the discovery and elimination of the new crown epidemic that occurs, so as not to allow the new crown virus to spread in the place where the epidemic occurred, but also to prevent the virus from spreading to other areas.

Dynamic clearing does not pursue zero infection, but to achieve the elimination of an epidemic, it also requires timely interruption of transmission in the place where the epidemic occurs, and no new infection occurs.

In other words, the country is not required to be free of new crown infections at a certain moment, but for every outbreak that occurs, it is required to be brought under control in a relatively short period of time.

　　He said that when there is no local continuous spread of the new crown epidemic, and the local new crown epidemic is mainly imported from abroad, the dynamic clearing strategy is the best choice, and "early detection" is the key to effectively and successfully controlling the new crown epidemic.

After the Hubei Defense War and the Wuhan Defense War, the local spread of the new crown epidemic in China was mainly caused by overseas imports.

The prevention and control practice in the past two years or more has proved that for imported clusters of new crown epidemics, we can find and eliminate them together.

"Dynamic reset" is to obtain the greatest social effect with the smallest social cost investment, which is in line with China's actual prevention and control, and is the best choice for China's prevention and control strategy.

　　Wu Zunyou emphasized that the current understanding of the new crown virus is still very limited.

In the future, the mutation of the new coronavirus and the development direction of the epidemic are very complicated. It may develop in the direction of increased infectivity and weakened pathogenicity, or it may develop in the direction of increased infectivity and pathogenicity.

"To be mentally prepared for the long-term fight against the new crown, we need to increase our confidence in defeating the epidemic, but we must not be deceived by those overly optimistic messages about the end of the epidemic. At the same time, we must also prepare for a possible large-scale new crown epidemic. No matter how we mutate, we have to prepare for the worst possible."

The pass system solves the bottleneck of cross-provincial logistics

　　Regarding the "hoarding" behavior in various places, Mao Dezhi, deputy director and first-level inspector of the Department of Cooperative Economics of the Ministry of Agriculture and Rural Affairs, said frankly that the total production of "vegetable basket" products in the country is guaranteed. In early April, the output reached 19.3 million tons, which is equivalent to providing 2.7 catties of vegetables per person per day.

In the first quarter, the output of meat, eggs and milk also increased by 8.8%, 2.5% and 8.3% year-on-year, respectively. The supply of aquatic products was stable, and in terms of volume, it could fully meet the consumption needs of the people. The main problem at present is the poor logistics and distribution in some areas.

　　In this regard, Wu Chungeng, director of the Highway Bureau of the Ministry of Transport, introduced that since April 11, the Ministry has set up a special class for road maintenance and smoothness, which conducts daily scheduling and guides localities to carry out self-inspection and self-inspection of closing toll stations and service areas. correct work.

As of the evening of April 18, 82.89% of the toll stations that were closed earlier had resumed normal operation.

"We will speed up the promotion of the use of nationally-uniform and mutually-recognized passports to ensure a uniform format, convenient handling, sufficient issuance, national mutual recognition, and smooth passage."

　　The establishment of a pass system for vehicles of key materials is an important measure to ensure the transportation of key materials across regions and provinces in an emergency.

Wu Chungeng revealed that as of April 17, 23 provinces in China have established a pass system as required, and 31 transit stations for emergency supplies in 10 provinces have been opened one after another.

　　In response to the distribution problems in the "last mile" and "last 100 meters" in some areas, Bian Zuodong, deputy director of the Market Supervision Department of the State Post Bureau, said that he will cooperate with the transportation of emergency supplies and daily necessities according to the actual needs of the local government. and delivery.

For example, in Shanghai, companies such as JD.com, China Post, SF Express, and YTO are actively using their respective advantages to go all out to help ensure the supply of urban materials.

Express companies such as JD.com have also dispatched unmanned smart express vehicles to carry out contactless delivery in sealed-off areas, effectively reducing the risk of the spread of the epidemic.
