Data shows that the number of new confirmed cases of new coronary pneumonia in the world has rebounded for the second consecutive week. The number of new local infections in my country is still at a high level, and the scope of the affected cities continues to expand. The epidemic is still in the developing stage.

  At the press conference held by the Joint Prevention and Control Mechanism of the State Council on March 25, Mi Feng, spokesperson of the National Health and Medical Commission and deputy director of the Publicity Department, said that it is necessary to improve the ability of epidemic monitoring, early warning and emergency response, and scientifically organize nucleic acid and antigen testing. Promote the collection of infected people and the separation of close contacts, completely block the community transmission of the epidemic, and achieve social clearance as soon as possible.

In 24 days, 28 provinces have been affected, and the epidemic prevention and control situation is still severe

  According to Lei Zhenglong, deputy director and first-level inspector of the National Health Commission's Bureau of Disease Control and Prevention, from March 1 to 24, more than 56,000 local infections have been reported nationwide, affecting 28 provinces.

Among them, the epidemic situation in Jilin Province is still at a high level. The epidemic situation in Shanghai, Hebei Province, Fujian Province, and Liaoning Province has grown rapidly in recent days, and the risk of community transmission continues to exist in the places where the epidemic occurred; Qingdao, Weihai, Zibo in Shandong Province, Shenzhen, Dongguan in Guangdong Province and other places The epidemic has been initially controlled; the epidemic situation in Beijing, Chongqing, Zhejiang Province and other places has stabilized.

  He said that the situation of epidemic prevention and control is still severe and complicated, and the comprehensive group of the joint prevention and control mechanism of the State Council will continue to guide the epidemic-related provinces to strictly implement various epidemic prevention and control measures to prevent the further spread of the epidemic. Responsibility, do not relax and do a good job in epidemic prevention and control.

  In response to social concerns about measures such as prohibiting cross-regional movement of people in some areas, suspending bus and subway passenger operations, and encouraging everyone to work from home, Wu Zunyou, chief epidemiologist at the China Center for Disease Control and Prevention, responded that these measures are helping to curb the spread of the new crown pneumonia epidemic. played a very important role in spreading.

For cases where the epidemic was discovered early, or the scale of the epidemic was small, or the chain of transmission was clear and definite, the epidemic could be effectively controlled through measures such as isolating and treating patients and isolating and observing close contacts.

Designated hospitals should intervene with antiviral drugs as soon as possible for six types of infected people

  A few days ago, the National Health and Medical Commission issued the "New Coronary Virus Pneumonia Diagnosis and Treatment Plan (Trial Ninth Edition)", which has aroused widespread concern in the 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 diagnosis and treatment plan paid more attention to infected persons over 65 years old, and the ninth edition was adjusted to those over 60 years old.

On the one hand, my country 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.

"We moved 5 years earlier and paid more attention to the elderly to avoid serious illness and death."

  "At the same time, a very 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, control viremia to the greatest extent, reduce organ damage and the risk of inflammatory factor storms, and effectively treat patients. "Wang Guiqiang said that for the elderly, those with underlying diseases, obese, heavy smokers, pregnant women, and those with low immune function, designated hospitals should intervene as soon as possible and use antiviral drugs.

  People who are at risk of aggravation should be identified in time.

"It can be identified by predictive and early warning indicators. We have set up a series of predictive and early warning indicators for patients to observe after hospitalization, including oxygenation index, oxygen saturation, inflammatory indicators, as well as ferritin, lymphocytes, etc., through these indicators to judge patients The risk of aggravation of the disease should be treated in time." Wang Guiqiang pointed out.

  According to Wang Guiqiang, the ninth edition of the diagnosis and treatment plan has also been adjusted according to the characteristics of the Omicron strain, mainly emphasizing the concept of "moving the gate forward", emphasizing early detection, early reporting, early isolation, and early treatment.

In terms of diagnosis, antigen detection is an important supplement to nucleic acid detection, especially at the level of control and home.

If it is found to be positive, it will be reviewed immediately in order to find out potential infected people earlier and isolate them in time to avoid further spread.

Omicron strain is still serious

  In response to my country's current epidemic prevention and control situation, Wu Zunyou said that striving to achieve dynamic clearing in a short period of time is still the most economical and effective new crown prevention and control strategy.

  He introduced that as the proportion of the population vaccinated against the new crown virus is getting higher and higher, and the population's immunity to the new crown virus is also improving. In addition, the pathogenicity of the Omicron strain itself is not as strong as that of other strains, and the clinical severity of the infected person is serious. According to the statistics of the number of cases per 100, the sex has indeed declined.

"However, asymptomatic infection is only a concept of a point-in-time state. Today's asymptomatic infection may become mild or common cases tomorrow or the day after, and we should pay more attention to the level of infectivity."

  "Because of the rapid spread of the Omicron virus strain and the large number of infected people, the total number of deaths and social harm and impact caused by the epidemic have not been alleviated." Wu Zunyou said that there is a study on relevant countries from August to October 2021. The case fatality rate and mortality rate in the two time periods from November 2021 to January 2022 were compared and analyzed. The first three months were dominated by the Delta strain, and the last three months were dominated by the Omicron strain. host.

The case fatality rate did drop during the Omicron epidemic, but the total number of deaths or fatalities due to the outbreak was higher during the same period than during the delta strain.

He pointed out that this shows that the Omicron strain is prevalent and the harm caused to a country as a whole has not been reduced.

The harm of the Omicron strain is still serious, and the new crown pneumonia is not a "big flu".

  "Currently, there are many mild cases and asymptomatic infections in Omicron. Most of the patients have upper respiratory tract infections and very little pneumonia." Wang Guiqiang pointed out that the symptoms of the upper respiratory tract are more obvious, which is more like influenza, which is also the reason for everyone. The cause of the "big flu" always comes to mind.

There are many similarities in clinical manifestations to influenza, such as coughing, sneezing, nasal congestion, etc., which should be highly concerned.

Vaccination is still an important means of epidemic prevention and control

  Data show that as of March 24, the country has reported 3.243599 billion doses of the new crown vaccine, and 1.240777 billion people have been vaccinated throughout the whole process, accounting for 88.01% of the country's total population.

  Lei Zhenglong pointed out that at present, the number of people over 60 years old who have completed the whole course of vaccination has reached 212 million.

Up to now, the vaccination rate of the elderly over 60 years old in 3 provinces of Jiangxi, Anhui and Shandong has exceeded 90%, and the 7 provinces and cities of Chongqing, Henan, Hubei, Guizhou, Hebei, Sichuan and Yunnan have exceeded 85%.

  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 course of vaccination can effectively reduce the risk of hospitalization, severe illness, and death, especially for the elderly with underlying diseases. Once infected with the new coronavirus, the risk of severe illness and death is higher than that of other groups. The new crown vaccine can effectively reduce the elderly. death risk.

It is hoped that everyone will complete the entire vaccination in time according to the program, and those who meet the conditions should complete the booster immunization in time.
