According to CCTV news, on February 23, the joint prevention and control mechanism of the State Council held a press conference on the consolidation of major achievements in epidemic prevention and control, and answered questions from the media.
Seven imported cases of XBB.1.5 have been detected in China
Chang Zhaorui, a researcher from the Department of Transmission and Prevention of the Chinese Center for Disease Control and Prevention, said that since the implementation of "Class B and Class B management" of COVID-19 infection on January 8 this year, seven cases of XBB 1.5 input cases have been detected in China. On February 3, a local associated XBB.1.5 case caused by the imported case was found in the sampling, and it was the core close contact person. After detailed epidemiological investigation, health monitoring of relevant close contacts and expert research, no further cases were found. According to the data from the CDC website of the United States, from February 12 to 18, XBB.1.5 ranked the first among the epidemic strains in the United States (about 80.2%), and accounted for a relatively high proportion of epidemic strains in several countries in Europe and the United States, such as Canada (37.8%), the United Kingdom (32.9%), and Germany (25.7%). Although XBB.1.5 has a strong transmissibility, the current data shows that the symptoms of individuals infected with XBB.1.5 are similar to those of other Omixon strains, and no increase in pathogenicity is found.
At present, in the monitoring of COVID-19 variants, if the first reported (including imported and local) and focused international epidemic virus strains are found, China will carry out case investigation of infected persons, core close knit investigation, and risk research and judgment. Once new variants with transmissibility, pathogenicity or increased virulence are found, measures will be taken in accordance with relevant plans in a timely manner. 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. According to expert research and analysis, it is unlikely to cause a new round of large-scale epidemic in the near future.
Does the "major decisive victory in epidemic prevention and control" mean that the current epidemic has ended? Liang Wannian responded
Liang Wannian, the leader of the expert group of the epidemic response and disposal leading group of the National Health Commission, introduced that the concept of pandemic is an indicator 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, that is, the disease and the epidemic situation are in the state of distribution among the population, that is, the normalized state of health. The second is an outbreak. A large number of cases occur in a short time in local areas or units, or in certain specific populations, which is called an outbreak. Another intensity indicator is epidemic. That is to say, the epidemic has spread widely and has spread across cities and provinces. The strongest strength is the pandemic, with transnational and transcontinental transmission. In March 2020, the World Health Organization announced that the epidemic situation was a pandemic. At the same time, it was announced at the end of January 2021 that the epidemic of this disease has constituted a public health emergency of international concern, and so far it is still a public health emergency of international concern. From a global perspective, the state of the pandemic still exists, and the harm of the disease still exists. However, it can be said that our country has achieved a major and decisive victory in the prevention and control of the entire COVID-19 epidemic. It is also a populous country that has successfully walked out of the pandemic. We have created a model.
Speaking of the signs of going out of the pandemic, in fact, there can be different indicators from different perspectives. From the perspective of epidemic prevention and control, especially public health, its indicators mainly include the following aspects: one is the status of the infection rate of this disease, the two key infection rates, the one is the cumulative infection rate, that is, the total infection rate in a certain period of time in a region, a country, and a population, That is, the cumulative infection rate. Another indicator of infection rate is the new infection rate. For example, how many people have new infections every day, and how many people have new infections in a specific population. Another indicator is the immune level or immune rate of the population. Its indicator is to judge the level of antibodies in his body, that is, the state of anti-immune barrier and immune protection rate. The third indicator is to see the pathogen, that is, whether COVID-19 has a qualitative and public health significant variation. If it is only a quantitative change in a subtype, but not a qualitative change, this indicator is also very important. The fourth is from the perspective of medical and health providers, the daily number of outpatient visits, hospitalization, severe illness, death, and the ability of the entire medical and health system to cope. This aspect is important. Finally, we need to see whether the whole prevention and control capability, from the mechanism to the means and ability to control the disease, is basically available. These aspects are important indicators to determine the pandemic.
Speaking of "decisive victory", in fact, for our country, it means that our country has withstood the impact and test of this round of epidemic and has established a relatively good population immunity 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 ended. The current infection in our country is still sporadic and sporadic.
WHEN THE SYMPTOMS OF FEVER AND DIARRHEA OCCUR, FOCUS ON WHETHER IT IS ACUTE GASTROENTERITIS, ETC
According to Chang Zhaorui, the main symptoms of COVID-19 infection are fever, dry throat, sore throat, cough, and some patients may have diarrhea. When the symptoms of fever and diarrhea occur, we should focus on whether it is acute gastroenteritis and other intestinal diseases, especially in the high incidence season of norovirus infection. Recently, the website of disease control institutions and WeChat official account have successively released Norovirus infection health tips, and the public can do a good job of protection according to the relevant tips.
AT PRESENT, THE OVERALL IMMUNITY LEVEL OF THE POPULATION IS HIGH, AND THE RISK OF LARGE-SCALE EPIDEMIC IS LOW
According to Chang Zhaorui, there are still cases of COVID-19 infection around the country, and there is still the possibility of infection among people who have not been infected in the past. The school is a place where people are concentrated and dense. Once the infectious source is introduced, the uninfected people will be at risk of infection. However, due to the high overall immunity level of the population, the risk of large-scale epidemic is low. When an epidemic occurs in a school, it is necessary to balance the relationship between the disposal of the epidemic situation and the normal teaching order, and the professional staff will conduct comprehensive research and risk assessment according to the students' previous infection level, the severity of the disease, the stage of the epidemic situation, and the infected virus strains, and make the disposal.
PREVENTIVE MEASURES RELATED TO COVID-19 INFECTION ARE ALSO EFFECTIVE FOR RESPIRATORY INFECTIOUS DISEASES
Chang Zhaorui said that the current epidemic season of respiratory infectious diseases such as influenza and respiratory syncytial virus infection in China needs to continue to strengthen the monitoring and early warning of influenza and other respiratory viruses; Nursery institutions, schools, nursing homes and other key institutions gather and have a relatively closed environment. They are places with high incidence of infectious diseases such as respiratory tract, which need to be focused on. Relevant institutions should monitor symptoms and report to local disease control institutions in time when there are more cases of fever and other symptoms. The local disease control institutions shall make corresponding treatment according to the released treatment plan for the aggregated epidemic situation of influenza and other related infectious diseases, and in combination with the epidemic scale and the actual situation on the site.
For influenza, annual vaccination is the most economical and effective preventive measure. At present, there is still COVID-19 infection in some parts of China. We should continue to do a good job in personal protection, adhere to good hygiene habits such as frequent hand washing, scientific wearing of masks, constant 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 proper exercise.
Preventive measures against COVID-19 infection are also effective for respiratory infectious diseases such as influenza and respiratory syncytial virus infection.
The situation of prevention and control of the epidemic situation in various regions is improving in general
Mi Feng, spokesman of the National Health and Health Commission, said that in the near future, the epidemic situation around the country has been sporadic, and the overall situation of prevention and control is improving, and has steadily entered the "Class B and Class B management" normalized prevention and control stage.
For more than three years, the National Health and Health Commission has always adhered to the optimization and adjustment of prevention and control policies and measures according to the time and situation, effectively coordinated the epidemic prevention and control and economic and social development, successfully avoided the widespread spread of virus strains with strong pathogenicity and high mortality, and effectively protected the life safety and health of the people. After the concerted efforts of the whole Party and the people of all ethnic groups to fight the epidemic, China has achieved a major and decisive victory in epidemic prevention and control.
