Expert interpretation: The virulence of the Omicron mutant strain is significantly weakened

　　In view of the characteristics of the spread of the new crown pneumonia epidemic, the joint prevention and control mechanism of the State Council organized relevant experts to further interpret hot issues.

　　The low proportion of severe cases usually manifests as aggravation of underlying diseases

　　Many people are concerned about the proportion of severe patients reported in some areas?

Will these severe cases be aggravated by infection with the new coronavirus?

　　Li Yimin, Chief Physician of the Critical Care Medicine Department of the First Affiliated Hospital of Guangzhou Medical University and Guangzhou Institute of Respiratory Health: In this wave of epidemics, we can actually see that the proportion of serious patients is not many, and the performance of these severe patients is mainly based on the basis The disease worsened, so he needed to go to the hospital for further treatment, and he recovered quickly after treatment.

This is completely different from the patients we have encountered before. It is not because of the aggravation of the new crown, but because he has an underlying disease and tested positive for the new crown at the same time.

At the same time, these manifestations in the lungs are different from the original manifestations of lung infection caused by the new crown. The manifestations in the lungs are not outstanding, and they are mainly due to the aggravation of underlying diseases.

So I hope we can face it correctly and don't worry too much at the same time.

　　The virulence of the Omicron mutant strain was significantly weakened

　　How virulent is the Amicron variant now?

Will it still cause pneumonia like in the past?

Can you think it's like the flu?

Clinical experts gave detailed answers.

　　Tang Xiaoping, Secretary of the Party Committee of Guangzhou Medical University: Compared with the previous original strain and other mutant strains, the newly popular Omicron virus strain, which is the current epidemic strain, we obviously feel that the virus's transmission ability is stronger. But its virulence was significantly weakened.

　　In the case of the original strain and the Delta strain last year, the proportion of pneumonia at that time reached more than half or even more than 60%, and the patients all had different degrees of pulmonary manifestations.

The vast majority of this wave, it should be said that more than 90% are asymptomatic infections and very mild mild manifestations, rarely pneumonia or severe pneumonia.

　　So far, more than 160,000 infected patients have been treated in Guangzhou, and there has been no death. Only 4 cases have been diagnosed as severe or above, and they are all related to lung infections caused by underlying diseases. There may be no direct relationship with the new crown infection. connect.

So I think the virulence of the current mutant strain should be significantly weakened, very close to seasonal flu, so I also hope that the general public will not panic, it is a disease that is preventable, controllable, and curable.

　　Omicron infection is very similar to flu symptoms

　　What are the symptoms that usually appear after being positive for the new coronavirus?

How is the current clinical treatment effect?

These issues are also of great concern to the masses.

Zhang Zhongde, an expert from the National New Coronary Pneumonia Epidemic Medical Treatment Expert Group and director of Guangdong Provincial Hospital of Traditional Chinese Medicine, answered these questions based on the clinical treatment experience of the Guangzhou epidemic.

　　Zhang Zhongde, vice president of Guangzhou University of Traditional Chinese Medicine and director of Guangdong Provincial Hospital of Traditional Chinese Medicine: Some patients have symptoms. We collected the symptoms of these patients and found that they were mainly fever, headache, sore throat, and dry cough. Some patients had general pain. and diarrhea symptoms, but these symptoms are very rare.

　　From our current analysis, it is mainly the symptoms of the upper respiratory tract, and rarely the symptoms of the lower respiratory tract.

According to the diagnostic process of traditional Chinese medicine, we found that the core pathogenesis of this wave is significantly different from that of the new coronary pneumonia at the beginning, and the symptoms are obviously going to be alleviated.

Now these symptoms look very similar to flu symptoms, and many symptoms are milder than severe flu or severe flu.

We think this wave is caused by wind-heat mixed with dampness, so our treatment plan based on the core pathogenesis is to dispel wind, clear away heat, and remove dampness.

　　Many symptomatic patients have fever, headache, and sore throat. These patients usually take two doses of traditional Chinese medicine a day after taking the medicine, usually 12 hours or 24 hours after taking the medicine. able to ease.

If there is a little cough after relief, then use traditional Chinese medicine for treatment, and the effect is also very good.

The nucleic acid of these asymptomatic patients, mild patients, or ordinary patients turned negative very quickly after recovery, usually 5 to 7 days, some patients took 11 days, and most of them turned negative in about 5 days.
