For some questions that netizens are most concerned about, we have found professional judgments ↓
Is the optimization of epidemic prevention policy "flat"?
Now the COVID-19 epidemic has not stopped, and it still appears in different parts of China. How to treat the situation caused by Omicron correctly now, some methods two years ago can no longer be used.
—— Zhong Nanshan, Academician of China Academy of Engineering
Some people try to lead the change of epidemic prevention and control measures to full liberalization and leveling, which is a distorted understanding. If we give up epidemic prevention and control, people's health, economic development, social stability and security will all face great pressure.
—— Tong Zhaohui, Vice President of Beijing Chaoyang Hospital affiliated to Capital Medical University
This kind of optimization is not completely open, but active optimization rather than passive optimization.
—— Liang Wannian, head of the expert group of the National Health and Wellness Committee's leading group for epidemic response and disposal.
Why start optimizing epidemic prevention policies now?
Scientific adjustment, continuous optimization, more scientific and more accurate, China's epidemic prevention policy in COVID-19 has been changing according to this "rhythm".
—— Zhang Boli, Academician of China Academy of Engineering
After nearly three years of global epidemic, with the constant variation of the virus, its pathogenicity gradually weakened. "From the characteristics of viruses and diseases, the necessary conditions for continuing to implement A-level management have gradually decreased."
—— Zhang Boli, Academician of China Academy of Engineering
The epidemic prevention policy is determined based on science, not the problem of tightness, but the problem of suitability.
—— Tong Zhaohui, Vice President of Beijing Chaoyang Hospital affiliated to Capital Medical University
Further optimization measures are aimed at ensuring people's life safety and health to the maximum extent and minimizing the impact of the epidemic on economic and social development.
—— Li Bin, Deputy Director of the National Health and Wellness Commission
Now choose optimization, isn't the previous efforts in vain?
By the end of 2022, the number of confirmed cases in China was 1 1/374, that in the United States was11348, and that in the world was 1/232. In the report released in May 20021,WHO expounded the prevention and control strategies and consequences adopted by four different countries around the world, and listed China's "strong prevention and control" as the best option.
—— Zhong Nanshan, Academician of China Academy of Engineering
The strict prevention and control in the past two years has actually won valuable time for universal vaccination and laid a solid foundation for the optimization and adjustment of epidemic prevention and control policies.
—— Tong Zhaohui, Vice President of Beijing Chaoyang Hospital affiliated to Capital Medical University
It takes time to get ready and improve the ability to cope, and it cannot be done overnight.
—— Liang Wannian, head of the expert group of the National Health and Wellness Committee's leading group for epidemic response and disposal.
In recent years, we have accumulated a lot of clinical experience and good treatment methods for COVID-19.
—— Guo Yanhong, Director of the Medical Emergency Department of the National Health and Wellness Commission
Can the epidemic prevention policy be optimized to return to normal life?
Further understanding of viruses and diseases, the decline of disease harmfulness, the supply of effective vaccines and drugs, and the improvement of emergency response and treatment ability are all key elements to restore the living conditions before the epidemic.
—— Liang Wannian, head of the expert group of the National Health and Wellness Committee's leading group for epidemic response and disposal.
It can be predicted that with the gradual normalization of life, we will face the great possibility of meeting COVID-19 unexpectedly.
—— Team Zhang Wenhong, Director of Infectious Diseases Department of Huashan Hospital affiliated to Fudan University.
Will the optimization of epidemic prevention policy lead to a surge in cases?
The epidemic prevention policy has been adjusted a little, which has no causal relationship with the surge in cases. It should be said that the surge in data may be caused by various reasons, and it has nothing to do with whether the "Article 20" is implemented or strictly enforced.
-Professor Jin Dongyan, Professor and Virologist, Department of Biochemistry, Faculty of Medicine, University of Hong Kong
Many so-called covert communication is actually that our personal preventive measures are not in place.
—— Wu Zunyou, chief epidemiologist of China CDC.
Will there be a medical run in the future?
Returning the new type of coronary pneumonia to class B management can release a lot of medical resources from the asylum hospital and return to normal diagnosis and treatment.
—— Zhang Boli, Academician of China Academy of Engineering
Co-ordinate the treatment of infected people in COVID-19 and the daily medical service guarantee, so as not to affect the normal medical service as much as possible, and ensure that other medical institutions can meet the medical needs of the masses.
—— Li Bin, Deputy Director of the National Health and Wellness Commission
At present, it is necessary to pay close attention to the variation of COVID-19, report the severe cases and deaths after infection, and the occupation of medical resources, so as to prevent a run on medical resources.
—— Li Bin, Deputy Director of the National Health and Wellness Commission
Is Omicron harmful now?
Omicron infection is not terrible, 99% can be completely recovered within 7- 10 days.
—— Zhong Nanshan, Academician of China Academy of Engineering
There are thousands of schemes to deal with COVID-19, but there is only one core problem. Should I go to the hospital if I am sick? Around this problem, it is very simple that 99.5% people may not need to go to the hospital. However, our medical system must ensure that 0.5% of patients should be admitted to hospital.
—— Team Zhang Wenhong, Director of Infectious Diseases Department of Huashan Hospital affiliated to Fudan University.
After being infected with Omicron in COVID-19, many people have no symptoms or relatively mild symptoms, but some people still have some "flu-like symptoms".
—— Team Zhang Wenhong, Director of Infectious Diseases Department of Huashan Hospital affiliated to Fudan University.
According to the data released by Singapore, the death rate of Omicron mutant in Singapore during the epidemic period of 65438+ 10/65438+10 in 2022 was 0.45‰, which was much lower than that of Delta mutant during the epidemic period of 65438+June -2022.
—— Li Lanjuan, academician of China Academy of Engineering and director of the State Key Laboratory of Infectious Diseases Diagnosis and Treatment.
What if I get infected?
For infected people who choose to be isolated at home for rehabilitation, while ensuring good food and rest, they also need to learn to monitor the following indicators by themselves: symptoms, temperature, pulse and oxygen saturation.
—— Team Zhang Wenhong, Director of Infectious Diseases Department of Huashan Hospital affiliated to Fudan University.
For young people without basic diseases, symptoms can usually be recovered within 3-5 days after adequate rest and enhanced nutrition. If the symptoms are obvious, they can be relieved by taking medicine, but the dosage should be taken according to the instructions and should not exceed the reasonable dosage range.
—— Team Zhang Wenhong, Director of Infectious Diseases Department of Huashan Hospital affiliated to Fudan University.
Generally, antipyretics are not recommended for low-grade fever or mild cough. In fact, there is no need for too much intervention. The symptoms of Omicron usually disappear within five to seven days after infection, so don't worry too much. Clinically, it is generally recommended to take antipyretics or Chinese patent medicines for clearing away heat and toxic materials when the fever is above 38.5 degrees Celsius.
—— Tong Zhaohui, Vice President of Beijing Chaoyang Hospital affiliated to Capital Medical University
Is COVID-19 really an "epidemic flu"?
At present, the virulence of the mutant strain should be obviously weakened, which is very close to seasonal influenza. I hope the general public will not panic. This is a preventable, controllable and treatable disease.
—— Tang Xiaoping, Party Secretary of Guangzhou Medical University
Now these symptoms look like flu symptoms, many of which are lighter than severe flu or mild flu.
—— Zhang Zhongde, Vice President of Guangzhou University of Traditional Chinese Medicine and President of Guangdong Provincial Hospital of Traditional Chinese Medicine
There are many similarities between COVID-19 and flu. Because their symptoms are very similar, it is difficult to tell whether they are COVID-19 or flu only by symptoms, and they need to be identified by laboratory diagnosis. Of course, some people may be infected with both COVID-19 and the flu. Compared with influenza, COVID-19 has a longer infection period and a faster spread. Most people infected with COVID-19 virus will lose their sense of taste or smell.
—— Wu Zunyou, chief epidemiologist of China CDC.
It is said that COVID-19 will have sequelae. Is that true?
At present, there is no evidence that Omicron infection will cause sequelae. From common sense, there should be no sequelae, because it is in the upper respiratory tract and does not affect the organs and tissues in our body. At least there is no relevant literature at home and abroad to support this statement.
—— Tong Zhaohui, Vice President of Beijing Chaoyang Hospital affiliated to Capital Medical University
Compared with Delta strain, the risk of COVID-19 sequela caused by Omicron strain is obviously reduced, and asymptomatic infected people basically have no COVID-19 sequela. The focus of prevention and control policies should shift from prevention and control of infection to prevention and control of severe diseases.
—— Zhong Nanshan, Academician of China Academy of Engineering
More important than medicine is to drink more water, rest more, enhance nutrition, be cheerful and not have pressure. These are more important than taking medicine.
-Ceng Guang, an expert in public health and epidemiology.
Can you do it without being infected?
If you take preventive measures yourself and your family and colleagues take preventive measures, the risk of contracting COVID-19 or flu will be greatly reduced.
—— Wu Zunyou, chief epidemiologist of China CDC.
In daily life, it is still necessary to correctly wear disposable medical masks or masks with protection levels above. Try to gather as little as possible and keep social distance in crowded places. During the flu and COVID-19 epidemic, you can rinse your mouth with iced salt water and wipe your nose with a cotton swab when you go out and go home every day.
—— Zhang Boli, Academician of China Academy of Engineering
You can prepare some drugs for treating colds and coughs at home, including antipyretic and analgesic drugs, Chinese patent medicines, conventional cold medicines, and daily medication. Beware of drugs that are advertised online but not commonly used.
—— Zhang Boli, Academician of China Academy of Engineering
People's awareness of self-protection should be enhanced, and everyone is the first responsible person for their own health. Keep a peaceful mind, free from anxiety and fear, and don't listen to rumors and false information.
—— Zhang Boli, Academician of China Academy of Engineering
One of the key points of prevention and control in the next step is to strengthen vaccination, especially heterogeneous vaccine. According to statistics, the risk of death is greatly reduced by any three doses of vaccine, especially for the elderly.
—— Zhong Nanshan, Academician of China Academy of Engineering
Why do you repeatedly emphasize the necessity of vaccination?
Vulnerable groups such as the elderly who are infected with COVID-19 are easy to develop into severe illness, critical illness or even death, and the benefits of vaccination with COVID-19 vaccine are the greatest.
—— Tong Zhaohui, Vice President of Beijing Chaoyang Hospital affiliated to Capital Medical University
According to research, compared with young people, after being infected with COVID-19 virus, elderly people over 65 years old, 75 years old and 85 years old are 5 times, 7 times and 9 times more likely to get seriously ill and 90 times, 220 times and 570 times more likely to die. If the elderly over 80 years old are not vaccinated with 1 dose, the risk of death is about14.7%; If 1 dose vaccine is inoculated, the risk of death will be reduced to 7. 16%. If three doses of vaccine are inoculated, the risk of death will be reduced to 1.5%. Compared with unvaccinated vaccine, the risk of death after three doses of vaccine was reduced by 9.3 times.
—— Xia Gang, Director of the Department of Health and Immunity of the National Center for Disease Control and Prevention
Vaccination is the main means to prevent viral respiratory infectious diseases.
—— Wu Zunyou, chief epidemiologist of China CDC.
From the data provided by Guangzhou Laboratory, it can be seen that compared with homologous inactivated vaccine immunization, heterologous immunization has induced a higher level of neutralizing antibody and enhanced the protection of various mutants.
—— Zhong Nanshan, Academician of China Academy of Engineering
Finally, I'd like to end with a quote from Academician Zhang Boli: Winter has arrived, and spring is not far away, not to mention early spring next year.
Earlier, Xinhua News Agency issued a document saying that "the most difficult period of fighting the epidemic has passed". China has become the country with the lowest incidence and the fewest deaths in COVID-19 among the major powers in the world. The medical and health care and disease control systems have withstood the test, and the complete vaccination rate of the whole people has reached more than 90%. At present, the pathogenicity of Omicron virus is weakening, and our ability to cope is increasing, which lays the foundation and provides conditions for the continuous optimization and improvement of prevention and control measures.
Clean up anxiety, cheer up confidence, eat and drink well!
From today on, protect yourself!
