The data shows that the number of new confirmed cases in the world has rebounded for the second consecutive week, the number of new indigenous infections in the mainland is still at a high level, the scope of the affected city continues to increase, and the epidemic is still in the development stage.
On March 25, Mi Feng, spokesman of the National Health Commission and deputy director of the Department of Publicity, said at the press conference of the joint prevention and control mechanism of the State Council that it is necessary to improve the ability of epidemic monitoring and early warning and emergency response, scientifically organize nucleic acid and antigen testing, promote the collection of infected people and the isolation of close contacts, completely block the community transmission of the epidemic, and achieve social clearance as soon as possible.
24 days affected 28 provinces The national epidemic prevention and control is in the stage of tackling tough problems
According to Lei Zhenglong, deputy director of the Disease Control Bureau of the National Health Commission and a first-level inspector, from March 1 to 24, the cumulative number of locally infected people reported nationwide has exceeded 56,000, affecting 28 provinces. Among them, the epidemic situation in Jilin Province is still at a high level, the epidemic in Shanghai, Hebei, Fujian and Liaoning provinces has grown rapidly in recent days, and the risk of community transmission in the place where the epidemic occurred continues to exist; the epidemic situation in Qingdao, Weihai, Zibo, Shandong Province, Shenzhen, Dongguan and other places in Guangdong Province has been initially controlled; the epidemic situation in Beijing, Chongqing, Zhejiang and other places has stabilized.
He said that at present, the national epidemic prevention and control is in the stage of tackling tough problems, and the epidemic prevention and control situation is still severe and complex. The Comprehensive Group of the Joint Prevention and Control Mechanism of the State Council continues to guide the provinces concerned with the epidemic to strictly and strictly implement various epidemic prevention and control measures, block the transmission as soon as possible, and prevent further spread. Areas where there is no epidemic should consolidate the responsibilities of all parties, implement normalized prevention and control measures, make preparations for emergency handling of the epidemic, and unswervingly grasp the prevention and control of the epidemic.
Will measures such as encouraging people to work from home help?
Regarding the measures taken in some areas to prohibit the movement of people across regions, as well as the suspension of bus and subway passenger transportation and the encouragement of everyone to work from home, Wu Zunyou, chief epidemiologist of the China Center for Disease Control and Prevention, responded that these measures have played a very important role in curbing the spread of the new crown epidemic. Generally speaking, for the early detection of the epidemic, or the scale of the epidemic is small, or the transmission chain is clear and clear, the epidemic situation can be effectively controlled by isolating and treating patients, isolating and observing close contacts, etc.
Which six types of infected people should be targeted by designated hospitals to carry out antiviral drug intervention as soon as possible?
A few days ago, the National Health Commission issued the "Diagnosis and Treatment Plan for Novel Coronavirus Pneumonia (Trial Ninth Edition)", which has aroused widespread concern in society.
So, what has changed in terms of treatment? Wang Guiqiang, director of the Department of Infectious Diseases at Peking University First Hospital, said that the original was over 65 years old, and the ninth edition was adjusted to over 60 years old. On the one hand, the mainland defines the elderly as 60 years old; on the other hand, from the current domestic and foreign research data, 60 years old is a very important node, that is to say, the number of people over 60 years old and over 65 years old who are equally at high risk of severe illness has increased. Therefore, the new version of the diagnosis and treatment plan is 5 years ahead of schedule, paying more attention to the elderly group and avoiding the occurrence of severe illness and death.
"At the same time, an important change in the new version of the diagnosis and treatment plan is to incorporate antiviral drugs into the diagnosis and treatment plan, which can effectively block the further development of the disease, maximize the control of viremia, reduce the risk of organ damage and inflammatory factor storms, and effectively treat patients." Wang Guiqiang made it clear that designated hospitals should intervene as soon as possible and use antiviral drugs for the elderly, those with underlying diseases, obesity, heavy smoking, pregnant women, and people with low immune function.
For the people who are at risk of aggravating their disease, Wang Guiqiang pointed out that it is necessary to identify them in time. "The method of screening, through the prediction of early warning indicators, we set a series of predictive early warning indicators after the patient is hospitalized, including oxygenation index, oxygen saturation, inflammation indicators, as well as ferritin, lymphocytes, etc., through these indicators to judge the risk of aggravation of the patient's condition, timely treatment, to avoid the patient's weight and death."
The Olmikron strain is prevalent, is the new crown pneumonia a "big flu"?
In view of the current epidemic situation in the mainland, "striving to achieve dynamic clearance in a short period of time is still the most economical and effective COVID-19 prevention and control strategy." Wu Zunyou said.
He introduced that with the increasing proportion of people vaccinated against the new crown vaccine, the population's immunity to the new crown virus continues to increase, and the pathogenicity of the Omiljung mutant strain itself is not as strong as other strains, and the clinical severity of the infected person is indeed reduced according to the proportion of each hundred patients. "However, asymptomatic infected people are only a concept of a point-in-time state, and today's asymptomatic infected people may also become mild or ordinary cases tomorrow or the day after tomorrow, and we should pay more attention to their level of infectivity."
"Due to its rapid spread and the large number of infected people, the total number of deaths caused by the epidemic and the social harm and impact have not been alleviated." Wu Zunyou said that there is a study of the case fatality rate and mortality rate of relevant countries in August-October 2021 and November 2021-January this year, the first three months are dominated by the epidemic of Delta strain, and the next three months are dominated by the epidemic of Theolmi kerong strain. The case fatality rate during the Omiljung strain epidemic did decline, but the total number or mortality rate due to the outbreak during the same period was higher than the number of deaths during the Delta strain epidemic. This shows that the epidemic of the Omiljung strain has not reduced the overall harm to a country. This also suggests that the harm of the Omiljun strain epidemic is still serious, and the new crown pneumonia is not a "big flu".
Wu Zunyou pointed out that the mainland is a large population country, a very small morbidity or mortality rate, multiplied by the population base of 1.4 billion, the absolute number will be very large. Only by achieving dynamic zeroing can we eliminate the hidden dangers of the epidemic, avoid the run on medical resources that may be caused by large-scale population infection, and prevent the possible death of a large number of elderly people or people with underlying diseases.
Many of the symptoms in the Case of Omikejong are similar to those of the flu, and experts recommend paying close attention to them
Wang Guiqiang pointed out that at present, Aomi Kerong is already the dominant poison strain on the mainland. In terms of clinical manifestations, there are now many mild cases and asymptomatic infections in Omikerong, and most patients present with upper respiratory tract infections and few manifestations of pneumonia.
"In fact, Omikron mainly exists in the upper respiratory tract, and the amount of virus in the lungs is small, so the performance of pneumonia is not much, and the symptoms of the upper respiratory tract are more obvious, which is more like the flu, which is why everyone always thinks of the problem of 'big flu'." There are many similarities with the flu in clinical manifestations, coughing, sneezing, nasal congestion, etc., which should be highly concerned. Wang Guiqiang said.
Is antigen testing recommended for ordinary people?
Wang Guiqiang stressed that antigen detection has been included in the new version of the diagnosis and treatment plan, and the state has also issued special guidance on antigen detection. Antigen detection is an important complement to viral nucleic acid detection, especially in the context of large-scale outbreaks of rapidly transmitting diseases like Omilon, and antigen detection is a very important supplement if the capacity of nucleic acid detection is insufficient. "However, antigen testing is still limited to controlled groups, isolated groups, and close contact groups, and we do not recommend that ordinary people conduct antigen testing." ”
At the same time, he pointed out that antigen testing cannot be used as a diagnosis of exclusion or as a substitute for 48-hour nucleic acid testing. Because there are certain false positives and false negatives in the antigen test, in the case of positive antigen tests, the nucleic acid review must eventually be carried out, but in the case of positive tests, it can be controlled in time to avoid the risk of further transmission.
The number of people vaccinated throughout the country accounts for 88.01% of the total population Experts call on 50 million elderly people to be vaccinated as soon as possible
According to the data, as of March 24, the country has reported a total of 3.24359 million doses of covid-19 vaccines, and 1.24 billion people have been vaccinated, accounting for 88.01% of the total population.
Lei Zhenglong pointed out that at present, the elderly over 60 years old have completed the whole process of vaccination to reach 212 million. Up to now, the vaccination rate of the elderly over 60 years old in Jiangxi, Anhui and Shandong provinces has exceeded 90%, and the vaccination rate of the elderly over 60 years old in Chongqing, Henan, Hubei, Guizhou, Hebei, Sichuan and Yunnan has exceeded 85%.
"At present, there are more than 264 million people aged 60 and over in the country, of which more than 212 million have been fully vaccinated against the new crown virus. From the analysis of the current monitoring results, the incidence of adverse reactions in the elderly over 60 years old is lower than that of other age groups. Wang Huaqing, chief expert of the immunization program of the Chinese Center for Disease Control and Prevention, said that from the results of previous clinical trials and the monitoring results of the current vaccine application, it has not been found that 80-year-olds are more likely to have adverse reactions.
Lei Zhenglong said that the current global epidemic situation is still severe and complex, and vaccination is still one of the important means of epidemic prevention and control. The whole process of vaccination can effectively reduce the risk of hospitalization, severe illness, death, especially the elderly mostly have underlying diseases, once infected with the new crown virus, the risk of severe illness and death is higher than other groups, after vaccination with the new crown vaccine can effectively reduce the risk of severe illness and death of the elderly, I hope that everyone will complete the full vaccination in time according to the procedure, and at the same time meet the conditions to complete the strengthening of immunization in time.
"In addition, I would like to emphasize that the elderly may have some physical discomfort after vaccination, and if you feel that the symptoms are more severe, or the duration is relatively long, or the recurrence of the original disease, we recommend that you seek medical treatment in time." If it is suspected that it is caused by the vaccine, it should be reported to the vaccination unit. Wang Huaqing said.
How can the elderly prevent coupling reactions after receiving booster injections?
Wang Huaqing said that it is necessary to objectively understand coupling disease. Coincidence is when the recipient is vaccinated, the recipient is already in an incubation period of a disease, or a state in the pre-morbid stage. After vaccination, the onset of the disease coincides, which is conjugation. In fact, coupling disorders have nothing to do with vaccination, nor are they adverse reactions after vaccination.
Why do older people have more couplings after vaccination? Wang Huaqing said that compared with adults and young people, the elderly have some health problems, and this probability may be greater. Some people have chronic diseases, some people are in the recurrence period of chronic diseases, and some people are in the incubation period of other diseases, so the risk may be high.
"Finally, I would like to emphasize that there are some couplings that we can avoid, but it is very difficult to avoid them completely when vaccinating." Wang Huaqing pointed out that the relevant departments put forward some precautions when vaccinating, such as when the elderly are feverish, are in the acute attack period of chronic diseases, and some neurological diseases are not controlled, including green bally, transverse myelitis and demyelinating disease and other related diseases, it is recommended to postpone vaccination and avoid the occurrence of some coupling diseases as much as possible.
