On April 12, at a press conference held by the joint prevention and control mechanism of the State Council, Mi Feng, spokesman of the National Health Commission and deputy director of the Department of Publicity, said that at present, the epidemic is still operating at a high level, the scope of the impact is further expanded, and prevention and control is in a critical period. It is necessary to continue to adhere to the general principle of "dynamic zero clearance" without hesitation and wavering, accelerate nucleic acid testing, the construction of square cabin hospitals, the admission and treatment of infected people, and block the spread of social aspects as soon as possible. At the same time, it is necessary to ensure the basic livelihood of the masses and the needs of medical treatment and drug purchase, and actively help solve problems.
In more than 40 days, 325303 cases of indigenous infections have been reported
According to data provided by the National Health Commission, from March 1 to April 11, 31 provinces (autonomous regions and municipalities directly under the central government) and the Xinjiang Production and Construction Corps reported 325303 cases of indigenous infections, affecting 30 provinces (autonomous regions and municipalities).
In this regard, Lei Zhenglong, deputy director of the Disease Control Bureau of the National Health Commission and a first-level inspector, said that with the implementation of epidemic prevention and control measures in various places, areas with new epidemics can be quickly and effectively dealt with, and no new large-scale epidemics have been formed. 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, and the number of new infections has dropped to less than 1,000 for three consecutive days, but it is still at a high level.
The number of new infected people in Shanghai in the next few days will remain at a high level 16 provinces have dispatched more than 40,000 medical personnel to support
Lei Zhenglong introduced that shanghai has reported more than 10,000 new infections for 8 consecutive days, the epidemic situation is in a period of rapid rise, community transmission has not been effectively curbed, and spillover from many provinces and cities, it is expected that the number of new infections will remain at a high level in the next few days.
"Up to now, the National Health Commission has dispatched more than 40,000 medical personnel from 16 provinces across the country and the capacity of 2.38 million tubes of nucleic acid testing per day to support Shanghai, and work with Shanghai medical staff to carry out medical treatment and nucleic acid testing of new crown pneumonia." Mi Feng said.
Promote material support for key epidemic areas such as Jilin and Shanghai
Since the recent outbreak of the epidemic in some areas, Xu Zhengbin, deputy director of the Economic Operation Regulation Bureau of the National Development and Reform Commission, introduced that the committee has fully launched the working mechanism related to the guarantee of living materials, and worked with the Ministry of Commerce, the Ministry of Agriculture and Rural Affairs, the Ministry of Transport and other relevant member units to strengthen communication and contact with relevant localities.
For the key areas of the epidemic, Xu Zhengbin pointed out that a daily reporting system for daily necessities has been established, tracking government reserves and commercial inventories, market supply, price fluctuations, etc., timely discovering emerging problems and taking targeted measures, and also launching a joint guarantee mechanism for living materials with neighboring provinces to establish a fast track for the transportation of living materials.
In view of the key epidemic areas such as Jilin and Shanghai, the National Development and Reform Commission has also set up a special work class on the basis of the work mechanism of the province, and has successively launched the inter-provincial joint guarantee and supply mechanism of the corresponding Jilin and Shanghai, and organized the relevant provinces and regions to quickly raise local vegetables and other supplies. At the same time, it has taken the initiative to coordinate with the State Railway Group to strengthen the transportation capacity guarantee for important daily necessities such as vegetables in Shanghai, and many batches of vegetables, rice and other materials have been rushed to Shanghai through the railway.
At the same time, he stressed that it is necessary to ensure the smooth flow of goods, coordinate and supervise the relevant localities to smooth the distribution of "last kilometer" and "last hundred meters" of materials, and jointly do a good job in ensuring the supply of living materials in the epidemic areas.
Is covid-19 serious due to infection with the Aomi Kerong variant? Is it harmful to the elderly?
Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, said that according to research and surveillance, the Aomi Kerong variant can cause severe illness and death. Because the standards and methods of monitoring vary from country to country, vaccination rates are different, the background of infection is different, and the infected population is different. Therefore, the proportion of severe illness and death caused by Omikeron varies from country to country. But there is a trend: if not vaccinated, the proportion of severe illness and death is still relatively high in the elderly and those including those with chronic underlying diseases.
Citing information provided by the Hong Kong Department of Health, Wang Huaqing said that during the epidemic of the Aumicrorong variant in the Hong Kong Special Administrative Region, the case fatality rate of the unvaccinated whole population reached 2.87%, and the case fatality rate of the unvaccinated elderly over 80 years old was as high as 15.68%. In addition, according to a new study in Hong Kong, in the current Epidemic in Omiquerong, the risk of death for people over 60 years old is 252 times that of people under 30 years old. Therefore, the data show that the Omikejung variant is still very harmful to the elderly, especially those who are not vaccinated and have chronic underlying diseases.
What is the latest progress in vaccination for the elderly?
Lei Zhenglong introduced that the number of people over 60 years old who are vaccinated has reached 224.777 million people, 213.293 million people have been vaccinated throughout the whole process, and 150.761 million people have been vaccinated.
He pointed out that vaccination is an important measure for epidemic prevention and control, especially the elderly have obvious benefits from vaccination. In order to further promote the vaccination of the elderly against the new crown, the National Office on Aging recently issued relevant documents, requiring all localities to fully understand the importance and urgency of vaccination for the elderly, and strive to promote the completion of vaccination as soon as possible for the elderly who have not yet completed the whole process of vaccination, and the elderly who meet the conditions for strengthening immunization can complete the enhanced immunization in a timely manner.
Why can't the mainland choose to "lie flat"?
In this regard, Wu Zunyou, chief expert of epidemiology of the Chinese Center for Disease Control and Prevention, said that the mainland's prevention and control practice for more than two years has proved that "dynamic zeroing" is in line with China's actual situation, and it is the best choice for the mainland to control the new crown epidemic in a timely manner at this stage.
In terms of the prevention and control strategy of the new crown, we have been exploring and continuously improving according to the progress of prevention and control. When the new crown virus first hit Wuhan, we adopted prevention and control measures based on physical isolation methods based on the previous experience in the prevention and control of SARS, especially the prevention and control of SARS, as well as the epidemic law and prevention and control strategy of acute respiratory infectious diseases, and finally successfully controlled the epidemic. Later epidemics are basically imported clusters of epidemics caused by imported cases from abroad, and every time they occur, we control and eliminate them together in a similar way, and it should be said that the application of our prevention and control strategies is still very successful. This can be summed up as "dynamic zeroing", and its purpose is to do everything possible to protect the health and safety of the people.
He said that "lying flat" is actually a helpless choice for some countries, after a variety of attempts, can not find an ideal strategy to control the new crown, so simply "lying flat", that is to say, in addition to strengthening vaccination, other prevention and control measures are no longer emphasized or simply not done. In some countries, the number of cases and deaths has risen sharply after the "lying flat".
Is there a risk of home isolation for asymptomatic infected people?
Some netizens believe that asymptomatic infected people can be isolated at home. In this regard, Wu Zunyou said that we must have a scientific understanding of "asymptomatic infected people", when diagnosing a person with asymptomatic infection, some of them are likely to be the incubation period of confirmed cases, and then observe that symptoms will occur after a period of observation, and even develop into severe disease, if not found in time, timely treatment, there will still be risks.
"This risk is manifested in two aspects: one is that it is possible to continue to spread the epidemic, and the other is that if he himself cannot detect the progress of his condition in time, he may miss the best treatment period, and may develop into severe illness or even pose a threat to his life." Wu Zunyou stressed.
Wu Zunyou said that centralized isolation has three advantages: First, all asymptomatic and mild cases of centralized isolation and observation, they are all infected, and there will be no problem of cross-transmission and spread. Second, during the centralized isolation period for asymptomatic and mild infected people, they can receive treatment of traditional Chinese medicine, which not only improves immunity, but also prevents the evolution into severe or critical illness. Third, if the patient has developed into a serious disease, he can be found and referred in time.
Can infection with the new crown virus prevent re-infection?
Wu Zunyou pointed out that a person can naturally develop a certain immunity after being infected with the new crown virus, but this immunity is not enough to prevent re-infection, and the duration of this immunity is not very long. The study found that after a person infected with the Delta strain, the risk of re-infection was lower than that of Theomi Kerong, that is, the risk of re-infection after the Infection of the Delta strain was higher than the risk of re-infection with the Delta strain after infection with the Delta strain.
The mutation of the new crown virus has been happening continuously, whether the virus becomes a new strain, or two viruses are reconstituted into a new virus mutation in the body, Wu Zunyou said that for individuals, it is mainly to implement protective measures, including wearing masks, hand hygiene, social distancing, etc., and to actively vaccinate against the new crown.
Some areas are about to enter the flying period, will the flying feather increase the risk of the spread of the new crown virus?
"In the past two years or so of research, no fly can adsorb the virus, and so far there are no reports of infection caused by fly feathers, it should be said that it will not." Wu Zunyou said that the new crown virus usually uses droplets as a carrier and adsorbs on the surface of tiny droplet particles, patients discharge droplets by coughing and sneezing, and virus adsorbs on particles with droplets discharged. Droplets are generally relatively small, at 1-5 μm, the distance of transmission should be 1-2 meters, when healthy people inhale droplet particles adsorbed by the virus, they are infected.
