The State Council Joint Prevention and Control Mechanism held a press conference at 15: 00 on February 23rd to introduce the situation of consolidating the major achievements in epidemic prevention and control. Pay attention together!
China has smoothly entered the stage of normalized prevention and control of "Class B and B Management"
Recently, the epidemic situation in various places has been sporadic, and the prevention and control situation has generally improved, smoothly entering the stage of "Class B and B management" normalization prevention and control. For more than three years, we have always insisted on optimizing and adjusting prevention and control policies and measures according to the situation, effectively coordinating epidemic prevention and control and economic and social development, successfully avoiding the widespread spread of virus strains with strong pathogenicity and high mortality, and effectively protecting people’s lives and health. Through the concerted efforts of the whole party and the people of all ethnic groups throughout the country to fight the epidemic, China has achieved a major and decisive victory in epidemic prevention and control.
At present, the global epidemic is still prevalent and the virus is constantly mutating. It is necessary to focus on "protecting health and preventing serious diseases", compact the "four-party responsibility", keep an eye on key links, continue to improve the measures of "Class B and B management", and further enhance the ability of normalization prevention and control and emergency response.
It is necessary to strengthen epidemic monitoring and normalized early warning, closely track and study the variation and spread of the virus, and improve the ability of early detection, early disposal and emergency response of the epidemic. Optimize the grading diagnosis and treatment mechanism and improve the ability of medical treatment. We will continue to prevent and control epidemics in nursing homes, social welfare homes, child care institutions and schools, and strengthen health services for key groups such as the elderly and children. Accelerate vaccination in COVID-19, raise people’s awareness of disease prevention, and build a social defense line for epidemic prevention and control.
What is the sign of getting out of the epidemic?
The concept of pandemic is an index reflecting the epidemic intensity of a disease. From the perspective of public health, the epidemic intensity of a disease epidemic can be divided into four categories, one is sporadic, the other is outbreak, and the other is epidemic, that is, the epidemic spread widely, achieving cross-city and inter-provincial spread. The strongest intensity is the pandemic, which has spread across countries and continents. In March 2020, the World Health Organization announced that this epidemic situation was a pandemic. At the same time, the epidemic situation of this disease announced at the end of January 2021 has constituted a public health emergency of international concern, and it is still a public health emergency of international concern. From a global perspective, the state of pandemic still exists, and the harm of the disease still exists. However, our country can say that the whole Covid-19 epidemic prevention and control, we have achieved a major decisive victory, but also as a populous country, successfully out of the pandemic, we have created a model.
Speaking of getting out of the sign of pandemic, we can actually have different indicators from different angles. From the perspective of epidemic prevention and control, especially public health, one indicator is what the infection rate of this disease is, and the other is the cumulative infection rate, that is, the total infection rate in a certain period of time among a region, a country and a population. There is also a new infection rate, such as how many people have new infections every day and how many people have new infections in a specific population. Another index is the immune level or immune rate of the population, which is to judge the level of antibodies in the body, that is, the state of anti-immune barrier and immune protection rate. The third indicator is to see the pathogen, that is, whether there is any qualitative and public health significance variation in Covid-19. The fourth is from the perspective of medical and health providers, the daily number of outpatients, hospitalization, severe cases, deaths, and the ability of the entire medical and health system to cope. Finally, it depends on whether the whole prevention and control ability, from mechanism to means and ability to control the disease are basically available. These aspects are important indicators to determine how to get out of the pandemic.
Speaking of "decisive victory", in fact, for our country, it means that we have withstood the impact and test of this round of epidemic and established a better population immune barrier. From the characteristics of the epidemic itself, it can be said that the epidemic has basically ended, but it cannot be said that it is completely over. In our country, the current infection is still in a sporadic and local sporadic state.
What are the infection symptoms of XBB.1.5? Is it possible to trigger a new round of infection peak?
Since Covid-19 was infected with "Type B B tube" on January 8th this year, 7 cases of local associated XBB.1.5 cases caused by imported cases have been found through monitoring, which are the core close contact personnel. After detailed epidemiological investigation, health examination of relevant close contact personnel and expert judgment, no further cases were found. According to the data of the CDC website in the United States, from February 12 to 18, XBB.1.5 accounted for the first place (about 80.2%) among the epidemic strains in the United States, and it also accounted for a relatively high proportion in several countries in Europe and America, such as Canada (37.8%), Britain (32.9%) and Germany (25.7%). Although XBB.1.5 has strong transmission power, the current data show that the symptoms of individuals infected with XBB.1.5 are similar to those of other Omicron strains, and no increase in pathogenicity has been found.
At present, in the detection of mutant strains in Covid-19, if the first reported (including imported and local) and international epidemic strains are found, the infection case investigation and core close contact investigation will be carried out, and the risk judgment will be carried out. Once a new mutant strain with enhanced transmission, pathogenicity or virulence is found, measures will be taken in time according to relevant plans. At the same time, China has just experienced a pandemic, and the neutralizing antibodies retained in the population will provide immune protection in a short period of time. Experts believe that it is unlikely to trigger a new round of epidemic in the near future.
Recent fever and diarrhea may be acute gastroenteritis.
After Covid-19’s infection, the main symptoms are fever, dry throat, sore throat and cough, and some patients may be accompanied by diarrhea. When there are symptoms of fever and diarrhea, we should focus on whether it is an intestinal disease such as acute gastroenteritis, especially at present, when norovirus infection is high. Recently, the website of CDC and WeChat WeChat official account have successively released health tips on norovirus infection, so the public can take precautions according to the relevant tips.
Preventive measures in COVID-19 are equally effective for respiratory infectious diseases.
At present, it is the epidemic season of respiratory infectious diseases such as influenza and respiratory syncytial virus infection in China, and it is necessary to continue to strengthen the monitoring and early warning of respiratory viruses such as influenza; Nursery institutions, schools, nursing homes and other key institutions are crowded and the environment is relatively closed. They are places with high incidence of infectious diseases such as respiratory tract and need to be paid special attention to. Relevant institutions should do a good job in symptom monitoring, and report to the local disease control institutions in time when there are more cases of fever and other symptoms. According to the published disposal plan of influenza and other related infectious diseases, local disease control institutions make corresponding disposal according to the scale of the epidemic and the actual situation on the spot.
For influenza, annual vaccination is the most economical and effective preventive measure. At present, Covid-19 infection still occurs in some parts of China, so we should continue to do personal protection, adhere to good hygiene habits such as frequent hand washing, scientific wearing of masks, frequent ventilation in rooms, keeping social distance and cough etiquette; Pay attention to maintaining a healthy lifestyle such as regular work and rest, reasonable diet and moderate exercise.
Preventive measures against Covid-19 infection are equally effective for respiratory infectious diseases such as influenza and respiratory syncytial virus infection.
Vaccination status of the elderly population in Covid-19
At present, the coverage of the elderly over 60 years old in China is 241.688 million, 230.306 million people have been vaccinated in the whole process, and 233.11 million people have been vaccinated. Based on the population of the national special survey of the elderly at the end of 2022, the coverage of vaccination accounts for 96.1% of the elderly population, and the whole vaccination and enhanced immunization account for 96.6% and 92.4% of the elderly population that meet the vaccination interval respectively.
How to dynamically grasp the infection level and changing trend of Covid-19 in China?
In December, 2022, in order to dynamically grasp the infection level and changing trend in Covid-19, timely monitor the variation of virus and biological characteristics, and evaluate the load of medical resources, the National Health and Wellness Commission, the National Bureau of Disease Control and Prevention, together with relevant departments, further expanded the monitoring channels and formed multiple monitoring subsystems on the basis of direct reporting of infectious diseases through the network. Including case report monitoring system, medical institution fever clinic (consulting room) monitoring system, sentinel hospital monitoring system, virus variation monitoring system, sewage monitoring system, key institution clustering epidemic monitoring system, crowd nucleic acid and antigen detection system, medical institution in-hospital case monitoring system, community crowd sentinel monitoring system, network survey system, etc. A multi-channel monitoring system has been initially formed, which takes into account normal and emergency situations, entry and local conditions, urban and rural areas, general population and key population.
In the next step, we will work with relevant departments to further improve the monitoring and early warning system, strengthen the capacity building of epidemic monitoring and normalization early warning, improve the quality of monitoring, strengthen the monitoring and early warning mechanism, and improve the team of interdisciplinary and multidisciplinary experts.
