"At present, the epidemic situation is still at a high level, the scope of the epidemic is further expanded, and prevention and control is in a critical period. We should continue to adhere to the general policy of" dynamic zeroing ", not hesitate or waver, strengthen confidence, be more resolute and decisive, and implement various prevention and control measures in every link." At the press conference held by the joint prevention and control mechanism of the State Council on the 12th, MI Feng, spokesman of the National Health Commission and deputy director of the publicity department, said that we should speed up nucleic acid testing, the construction of shelter hospitals and the admission of infected people, so as to block social transmission as soon as possible. We should strengthen risk control, conduct rapid screening, find out potential infectious sources, and transport and isolate them in time. We should earnestly ensure the people's basic living and medical needs, and actively help solve problems. From March 1 to April 11, 31 provinces, autonomous regions and cities and Xinjiang production and Construction Corps reported 325303 cases of local infection, affecting 30 provinces, autonomous regions and cities. Lei Zhenglong, deputy director of the Bureau of disease control and prevention of the National Health Commission and first-class inspector, said that with the implementation of epidemic prevention and control measures in various regions, new epidemic areas can be handled quickly and effectively without forming a new large-scale epidemic. The epidemic situation in Hebei, Jiangsu, Anhui, Guangdong, Fujian, Zhejiang, Shandong and other provinces is generally controllable. The overall epidemic situation in Jilin Province showed a downward trend, but it was still high; The number of newly infected people in Changchun has decreased every day, but the community transmission in the control area has not been completely blocked. It is still necessary to continue to strengthen the prevention and control work in the control area. Shanghai has reported more than 10000 new infections for eight consecutive days. The epidemic is in a period of rapid rise. Community transmission has not been effectively curbed, and has spilled over to many provinces. It is expected that the number of new infections will remain high in the next few days. Xu Zhengbin, deputy director of the economic operation regulation Bureau of the national development and Reform Commission, said that since the recent outbreak of the epidemic in some areas, the national development and Reform Commission has fully launched the working mechanism related to the guarantee of living materials. The key work includes: strengthening the monitoring and dispatching, establishing the daily reporting system of living materials in key areas of the epidemic, tracking the government reserves and commercial inventories, market supply, price fluctuations and other situations, timely discovering emerging problems and taking targeted measures. Establish a full coverage coordination mechanism for sub provinces, regions and cities, strengthen the connection with the contracting provinces, regions and cities, timely understand the situation and difficulties of living material support, and help coordinate and solve them. At the same time, actively supervise and coordinate, pay close attention to the connection between production and marketing, and strengthen key guarantee. "On the whole, in the recent period, the supply of important livelihood commodities in China has been abundant, the prices have been basically stable, the prices of grain and oil have remained stable, the prices of pork have remained low, the prices of beef, mutton and chicken have been relatively stable, and the prices of eggs have increased slightly." Xu Zhengbin said, but we should also see that since mid March, vegetable prices have increased significantly due to the impact of logistics obstruction and rising costs caused by multiple epidemics, especially in Shanghai, Changchun and other places. Recently, with the implementation of measures to ensure supply and stabilize prices, prices began to fall step by step. Li Danghui, deputy director of the Department of consumption promotion of the Ministry of Commerce, said that for the key areas of epidemic prevention and control, the Ministry of Commerce has launched the joint guarantee and supply mechanism of "multiple parties and one party", timely mobilized the market resources and guarantee and supply forces of surrounding provinces and living material extension base provinces, and maintained the normal operation of key areas. As of April 11, Inner Mongolia, Zhejiang, Fujian, Jiangxi, Shandong, Henan, Hubei, Sichuan, Guangxi, Yunnan, Ningxia and other provinces had supplied 18000 tons of vegetables, 850 tons of rice noodles and 500 tons of meat and eggs to Shanghai. In addition, they also supported more than 5400 tons of vegetables, fruits, milk, bread, canned food and so on free of charge. Li Danghui introduced that for a series of problems such as the "one size fits all" control of freight vehicle traffic, distribution and storage in some regions, resulting in the decline of cross regional transport capacity and the impact of supply guarantee, the Ministry of commerce actively played the role of departmental linkage and cooperated with relevant departments to study and propose measures. In view of the problems of poor logistics and delivery of "the last kilometer" and "the last 100 meters" in some cities, on the basis of summarizing the experience of protection and supply in the closed management area of prevention and control, timely copy and promote the new experience and practices of anti epidemic protection and supply in Liaoning and other places, so as to effectively improve the efficiency of household entry of living necessities. At present, China has a high proportion of light cases and asymptomatic infections. Some people believe that centralized isolation has the risk of causing a run on medical resources. It is recommended to isolate at home, but others believe that there will be a great hidden danger of social transmission for asymptomatic infected people. Wu Zunyou, chief epidemiologist of China CDC, explained that some asymptomatic infected people are likely to be in the incubation period of confirmed cases. After observation for a period of time, they will have symptoms and even develop into severe cases. There are risks in home isolation. First, it may continue to cause the spread of the epidemic. Second, if the progress of the disease is not found in time, the best treatment period may be missed, which may develop into severe disease and even pose a threat to life. If there are mild and asymptomatic infections, these people should be concentrated to the designated isolation point for isolation observation as far as possible. Some infected people are too late or have not been transferred to the isolation point for treatment. How should we do a good job in epidemic prevention? Wu Zunyou said that the first thing to do is to reduce transmission within the family. Infected people should live in a bedroom alone, preferably with an independent bathroom, and do not eat with their families. Second, reduce the risk of infection to neighbors or other community residents. The infected family should disinfect the living room, toilet and other environment in time. The infected family members should not visit the door with luck. During the period of sealing and control management and health monitoring, each resident should pay attention to the changes of their physical condition, whether there are symptoms such as throat itching, throat pain, cough and fever, and conduct self-test by antigen detection method. In case of suspected symptoms or positive antigen screening, contact the local epidemic prevention department in time. As of April 11th, the national total reported 3 billion 300 million doses of COVID-19 vaccine 328 thousand times, the number of people who completed the whole process of vaccination was 1 billion 200 million 44 million 923 thousand. The number of people over 60 years old covered by vaccination reached 224.777 million. Wang Huaqing, chief expert of immunization program at China CDC, said that vaccination with COVID-19 vaccine had very good effects on preventing COVID-19 and severe and death caused by the prevention of the strain. Call on eligible elderly people to be vaccinated as soon as possible, vaccinate the whole process as soon as possible, and strengthen vaccination as soon as possible when they meet the conditions.
