The joint prevention and control mechanism of the State Council held a press conference at 3 p.m. on April 12 to introduce the situation of strictly and earnestly grasping the epidemic prevention and control work.
What is the overall situation of the current national epidemic situation?
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 a cumulative total of 325303 cases of indigenous infections, affecting 30 provinces (autonomous regions and municipalities). With the implementation of epidemic prevention and control measures in various places, areas with new outbreaks can be dealt with quickly and effectively, 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 trend of the epidemic in Jilin Province has dropped to less than 1,000 cases, and the number of new infected people in Changchun City has declined every day, but the community transmission in the control area has not been completely blocked, and it is still necessary to continue to strengthen the prevention and control work in the control area. Shanghai has reported more than 10,000 new infections for 8 consecutive days, the epidemic is in a period of rapid rise, community transmission has not been effectively contained, 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 ability of 2.38 million tubes of nucleic acid testing per day to support Shanghai, and together with shanghai medical staff to carry out medical treatment and nucleic acid testing of new crown pneumonia.
Why insist on "dynamic zeroing"?
In terms of covid-19 prevention and control strategies, we have been exploring and continuously improving according to the progress of prevention and control work and our updated understanding of COVID-19.
When the new crown first hit Wuhan and the epidemic occurred, we adopted prevention and control measures 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 and basically eliminated the new crown epidemic in China.
Later epidemics are basically imported clusters of epidemics caused by imported cases from abroad, every time they occur, control together, eliminate together, it should be said that the application of our prevention and control strategy is still very successful, this prevention and control strategy can be summarized as "dynamic zero", the biggest purpose of this "dynamic zero" is to maximize everything possible to protect the health and life safety of the people.
In many countries, it is still very difficult to apply such a comprehensive comprehensive disposal in a physically isolated manner and achieve zero clearance. "Lying flat" is actually a helpless choice for other countries, after a variety of attempts, can not find an ideal strategy to control the new crown, so simply "lie flat". The so-called "lying flat" means that in addition to strengthening vaccination, other prevention and control measures are no longer emphasized or simply not done. After some countries "lie flat", the number of cases and deaths has risen sharply, at which time these countries have shrunk back, tightened their prevention and control strategies, and added other prevention and control measures.
The mainland's prevention and control practice for more than two years has proved that "dynamic zero clearance" is in line with China's actual conditions and is the best choice for the mainland to control the new crown epidemic in a timely manner at this stage.
Can an asymptomatic infected person be isolated at home?
We need to have a scientific and accurate concept of "asymptomatic infected people", when we diagnose a person with asymptomatic infection, some of them are likely to be in the incubation period of confirmed cases, and after observing for a period of time, symptoms will appear, and even develop into severe disease.
Staying at home is still risky. It 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 a serious illness or even pose a threat to life.
Centralized isolation has three advantages: First, all asymptomatic and mild cases observed in centralized isolation are infected people, and there will be no problem of cross-transmission and spread. Second, during the period of centralized isolation, you can receive treatment from traditional Chinese medicine to improve immunity and prevent it from evolving into severe or critical illness. Third, if the patient has a situation of developing into a serious disease, it can be found and referred in time.
Therefore, if there are mild and asymptomatic infected people, these people should be concentrated at designated isolation points for isolation and observation as much as possible.
How should the family and neighbors of a positive infected person be prepared before being transferred to the isolation point?
For some infected people who have just been diagnosed positive and are too late to transfer to the isolation point, first, to reduce the risk of transmission within the family, there should be a bedroom to live alone, it is best to have a separate bathroom, do not eat with the family, do not communicate with the family; second, reduce the risk of infection to neighbors or community residents, the positive infected family should disinfect the living room, bathroom and other environments in time, resolutely put an end to the phenomenon of door visits, and resolutely eliminate activities and communication with people in the community.
For residents living in the same building or community, after the patient is not transferred out or transferred for a period of time, the entire building and community belong to the stage of sealing and control management, and each household is isolated at home and abides by the regulations of staying at home. During the period of sealing and control management and health monitoring, everyone should pay attention to observing changes in their physical condition, whether there are symptoms such as itchy throat, sore throat, cough, fever, etc., self-testing through antigen detection methods, if there are suspected symptoms, or antigen tests are positive, they should contact the local epidemic prevention department in time for timely disposal.
What is the probability of "material transmission" of Omicron?
The length of time that the new crown virus survives on the surface of the object depends on the amount of pollution, as well as the temperature, humidity, light and ultraviolet rays in the environment, generally speaking, the risk of human infection caused by surface pollution is relatively small, but if we repeatedly contact, and do not pay attention to hand hygiene, and do not pay attention to personal protection, its risk will increase significantly.
Therefore, we conduct regular testing of foreign-related cold chain and foreign-related freight personnel in order to find infected people in time. For ordinary people, in daily life, the express package should be disinfected and then opened, the risk is greatly reduced at this time, and insisting on hand hygiene can reduce the risk of infection with the new crown due to contact with contaminated surfaces.
If you have been infected with Delta or Olmikeron, will you be infected again?
If a person has been infected with delta or Omikejong strains, it is still possible to re-infect an infected person without taking any protective measures. The study found that the risk of re-infection after Aomi kerong infection was higher than the risk of re-infection with Delta strain after infection with Delta strain.
Is the rate of severe illness and mortality high due to Omi kerong?
According to studies and surveillance, the Aumecreon variant can also cause severe illness and death. Due to the different standards and methods of surveillance in different countries, the vaccination rate is different, the background of infection is different, and the infected population is different. We see some data showing that the proportion of severe illness and death caused by Omi kerong varies from country to country. But there is a trend and characteristic that if there is no vaccination, the proportion of severe illness and death is still relatively high for the elderly and those who include chronic underlying diseases, which is also a place that makes us particularly worried.
The World Health Organization publishes the number of cases and deaths in various countries and some relevant areas every day, and during the epidemic of the Omikerong variant, not only did it see the incidence reach an all-time high, but the number of deaths also reached a peak. The United States reported more than 15,000 COVID-19 deaths for five consecutive weeks during the Omiljung epidemic.
According to information provided by the Hong Kong Department of Health, when the Omiljunn variant was endemic in Hong Kong Sar, the case fatality rate of the unvaccinated population reached 2.87%, and the case fatality rate of the unvaccinated elderly over 80 years old was as high as 15.68%. According to the latest research in Hong Kong, in the current Epidemic in Omikerong, the risk of death for people over 60 years old is 252 times higher than the risk of death for people under 30 years old.
Through the above data, we can see that the Omiljung variant is still very harmful to the elderly, especially those who are not vaccinated and have chronic underlying diseases.
What is the difference between the protective effects of no vaccination and two or three doses of vaccine?
According to a recent study in Hong Kong, three doses of covid-19 vaccine can reduce the risk of severe illness and death by more than 90%.
On April 8, a new study in Hong Kong showed that among people over the age of 60, the relative risk of death from no vaccination was 21 times that of people who received two or more doses.
According to information released by the Hong Kong Department of Health, the case fatality rate among the unvaccinated population is 2.87%, the case fatality rate among the whole population who have received two doses is 0.14%, and the case fatality rate of three doses is 0.03%. Compared with unvaccinated, the difference is 20 times and 95 times, respectively.
Will flying feathers lead to the risk of the spread of the new crown virus?
The new crown virus is generally not transmitted directly from an infected person to a healthy person in the form of a free virus, the new crown virus usually uses droplets as a carrier, adsorbed on the surface of tiny droplet particles, patients cough, sneeze droplets are discharged, and viruses are adsorbed on the particles with droplets discharged. Droplets are generally relatively small, at 1-5 microns, the distance of transmission should be 1-2 meters, when healthy people inhale droplet particles adsorbed by the virus, they are infected. In more than two years of research, no fly has been found to adsorb the virus, and so far, there have been no reports of infections caused by fly feathers.
