At 15 pm on December 14, Gao Fu, academician of the Chinese Academy of Sciences, was invited by the University of Chinese Academy of Sciences to give an online lecture
on the theme of "Epidemic Prevention and Control under the New Situation".

Academician Gao Fu emphasized in the lecture that vaccines provide four levels of protection: infection prevention, disease prevention, transmission prevention, severe disease prevention, and death
.
At present, the first three prevention - to prevent the spread of infection, immunization is greatly reduced, but the efficiency of preventing severe disease and preventing death is still very high
.
And although the prevention of infection, disease prevention and transmission is greatly reduced, if infected, the symptoms will be relatively mild, the burden of disease will be relatively light, and there may be no need to be hospitalized or take any medicine
.

In addition, Academician Gao Fu said that hospitals should not be treated as vegetable markets, but should be treated in an orderly manner and practice hierarchical medical treatment
.
"For example, mild cases and young people, do not go to the hospital, leave the limited treatment resources of the hospital to the elderly and people
with underlying diseases.
"

The following is the transcript of Academician Gao Fu's lecture (abridged in the health sector):

Why are many people in the world worried about China's liberalization?

In pathology, Omicron mainly proliferates and replicates in the respiratory epithelium, and has a strong proliferative and replicative ability, but weak proliferative replication in the lungs; It is relatively contagious
.

Why did Omicron appear? Now there are three hypotheses:

The first hypothesis is that the virus has existed for a long time, but after competition, it has become advantageous on its own
.

The second hypothesis is that it originally hid in the fauna, spread quietly, and then suddenly ran out of the fauna
.

The third hypothesis is that it is caused
by immune escape.

Because the Omicron strain was first detected in South Africa, and in African countries like South Africa, HIV infection rates are high, with almost 1 in 5 people being positive
.
AIDS patients have immunosuppression, these people are not vaccinated enough, when the virus spreads in this type of population, it may not be an acute infection, relatively speaking, the virus stays in the human body longer, so it leaves an opportunity
to adapt to the individual.

Now that China has opened up, it has also aroused the concern of many people in the world
.
Because we have a habit in Chinese, when we are sick and anxious, we love to run to the hospital to buy medicine and take medicine
.
In fact, this habit is not good, everyone absolutely do not go to the hospital to squeeze, do not take medicine indiscriminately, take more medicine, but force the virus to appear new mutations
.

This is also why the international community is worried about whether some new variant strains
will appear in the world when a new round of epidemic begins in China.

To be honest, this virus has been fighting humans, like a cat-and-mouse game
.
We humans should have had several opportunities to eliminate it, for example: if we could detect the virus earlier in Wuhan or other places, we could eliminate the virus, or drive it out of the crowd and not spread it in the population, which could weaken the virus or eliminate
the virus.
But those opportunities were gone, so we had to wait a long time with the virus
.

Recently, the Internet said that there is a new strain called Dog of Hell in Japan, is it that powerful?

In fact, it is a new variant of Omicron, which has not been found to be more pathogenic or transmissible
.
Even the results of the Institute of Medical Sciences at the University of Tokyo believe that it may not only not have become stronger but weakened, so people must not believe these rumors on the Internet
.

But there is a basic concept, everyone must know, Omicron is still a new crown virus, is a wolf to eat sheep, this is a big ecology, without mutton, how do wolves live?

When the virus spreads in the population, it is likely to cause severe illness or death in people, resulting in large group infections
.
Therefore, the fear of coronary is not right, and it is not right to underestimate the enemy, everyone should think about how to prevent and control the new crown
in the current new situation with a peaceful attitude.

As of November 27, 2022, the number of new crown deaths reported globally is shown in the figure below, and now that the northern hemisphere has entered winter, the situation is relatively serious
.

The global population now has 640 million cases and fewer than 7 million deaths, while the 1918 flu pandemic was estimated to have caused 25 million to 50 million deaths
.

Why is the death rate of the new crown so well controlled? This is not to say that it seems that Covid is not deadly, but because of science
.
After the Chinese people found the virus, they first isolated the virus, sequenced it, shared the sequence around the world in less than a week, and then began to develop vaccines around the world, and humans used vaccines
in less than a year.
Drug research and development has played a very important role in the victory over the new crown, and non-pharmaceutical interventions that have united people around the world have also played a role
.

Despite our mistakes, overall, humanity has been able to keep the number of COVID deaths below 7 million, which is a considerable achievement
in the context of the pandemic.

What have we been struggling with?

Let's look at the local epidemic situation in our country, which is now a new high
.
On April 8, 2020, after Wuhan lifted the lockdown, there were very few cases in China, and since then, there have been some imported cases
across the country.
Every time we enter, we adhere to the basic policy strategy of "dynamic zeroing, external defense input, internal defense rebound", which is basically well controlled, but it has been uncontrollable since the beginning of this year
.

In fact, at the end of last year, I had a hunch that it was difficult for a country or place to control the virus, it was quite difficult, there may be hope for clearing the disease, and the hope for detoxification was very small
.

At the end of last year, I had a hunch that it was difficult for a country or place to control the virus, it was quite difficult, there may be hope for clearing the disease, and the hope for detoxification was very small
.

Under the current new situation of epidemic prevention and control, I would like to remind everyone that we believe in science and scientific prevention and control, and must pay attention to the prevention and control of the "information epidemic", and the most troublesome thing about it is that correct and incorrect information are put together
.

In three years of scientific prevention and control, we have made great achievements
.
We protect lives and our loss of life is the lowest globally; We have gained time, enough time for us to develop enough vaccines and drugs; There is also psychological preparation, preparation of materials, etc
.

Why should epidemic prevention and control measures be optimized? It is completely based on the changes in the international and domestic situation, the characteristics of the Omicron variant, and the evaluation of our comprehensive prevention and control measures in the past three years, so that we can do prevention and control work more scientifically and
accurately.

We have always been border prevention and control, while researching, summarizing, and adjusting, and have always adhered to the principle of this, while adhering to three orientations: problems, needs, and goals
.
Now that the virus is not gone, then we will find a way to coexist
with the virus.

What have we been struggling with? As we all know, infectious diseases have three elements: the source of infection, the route of transmission, and the susceptible population
.
If everyone is vaccinated and not infected, the susceptible population will be gone, and the infectious disease will be gone; The source of infection has been hit, isn't the infectious disease gone?

Therefore, from dynamic zero clearance to precise prevention and control, the core question is whether to care about the source of infection? Today, our strategy adjustment is not tangled, we clean up the disease but not the poison, which is very important
.
Of course, it is impossible to clear the disease, but find a way not to make him sick, treat him if he has a disease, have fewer lesions, and have a lighter illness
.

Today, the Comprehensive Group of the Joint Prevention and Control Mechanism of the State Council issued the Notice on Printing and Distributing the Implementation Plan for the Second Dose of Booster Immunization of the New Coronavirus Vaccine, which proposes that the second booster immunization can be carried out in high-risk groups, elderly people over 60 years old, people with more serious underlying diseases and immunocompromised people in the emergence stage
.

Depending on the protocol, priority is given to sequential booster immunization or a second booster dose with vaccines containing or with good cross-immunization against the Omicron strain
.

To clear the disease and not the poison, the key here is coexistence and isolation at different levels
.

The next step, the most critical thing is to return this disease from "Class B tube" to "Class B tube", which is the general direction
of adjustment.

Orderly infection, distribution infection

The current situation is a variety of pathogenic epidemics intertwined, especially in the north, including influenza, bacteria, respiratory syncytial virus, rhinovirus, adenovirus, etc.
, all kinds of viruses will cause colds in winter, we must pay attention to identification
.

If it is a new crown and you suspect pneumonia, you must go to the hospital; If not, don't run out of hospital resources
.
This is why home antigen testing makes sense
.
So now there is a question, I once again said that I am not a clinical doctor, I just tell you a little personal experience, what to do if you are yang?

Zhang Wenhong proposed orderly infection, that is, distribution of infection, although this disease can not be controlled, but we must allocate infection, the key is not to cause a run on medical resources, once the medical resources run, will cause catastrophic damage, so everyone must pay attention
.

This made me wonder if we can seize this crisis to change a mindset
.
The biggest challenge facing health care reform has always been to treat hospitals as wet markets, where they have to go to buy things
as if they were cooking every day.
In some other developed countries, going to the hospital to see a doctor is an appointment system, I hope everyone also follows such an appointment system, which requires Chinese people to change their concepts, can not treat the hospital as a vegetable market, we must see a doctor in an orderly manner
.

It is very important that hierarchical medical care, such as mild cases and young people, should not go to the hospital to squeeze, leaving the limited treatment resources of the hospital to the elderly and people
with underlying diseases.

We should learn lessons from this epidemic, sum up experience, and make China's medical reform really on the right track in the future, clarify the functions of large hospitals and small clinics, and not run to big hospitals for many diseases, and get small clinics to have nothing to do
.

I hope to raise awareness through this epidemic, some diseases may not need to go to small clinics, and they can be solved in community service centers, and some may be The CDC (Center for Disease Control) system is solved, such as influenza vaccination for key groups every winter, local CDC, community service centers can be solved, and clinics do not have to go, which I call on everyone to pay attention
to.

Back to the topic
of what to do if the sun is over.
The results of the current study demonstrate that once positive, once there is a viral infection, the viral load and symptoms are positively correlated
.
Therefore, when the viral load is high, the fever is high, the course of the disease is long, and the muscle pain is obvious
.

In such cases, symptomatic treatment should be antipyretic
.
There are also ways to reduce viral load with some specific and non-specific drugs, such as the monoclonal antibody nasal spray and peptide inhibitor nasal spray that are recently in clinical trials, which can completely reduce the viral load of the upper respiratory tract, like these things can be used
.

At home, you need to prepare an oxygen saturation clip to see the blood oxygen saturation, which is very important
.
If the oxygen saturation is below 85, or close to 85 -Pay attention when you are 90; If it is greater than 90, everyone really does not worry, there is no need to run on the resources
of the hospital.

We must note that we are better off infecting in batches, giving the virus a chance to make it more virulent, and further allowing time for us to get the next booster dose and further build up our immune barrier
.

What is the most critical thing for epidemic prevention and control under the new situation? I once again call on everyone to fight the vaccine, believe in science, and vaccines provide four levels of protection: infection prevention, disease prevention, transmission prevention, severe disease and death
.
At present, the first three prevention - to prevent the spread of infection, immunization is greatly reduced, but the efficiency of preventing severe disease and preventing death is still very high
.
And although the prevention of infection, disease prevention and transmission is greatly reduced, if infected, the symptoms will be relatively mild, the burden of disease will be relatively light, and there may be no need to be hospitalized or take any medicine
.
Therefore, everyone must have such a high degree of awareness of vaccines, and now 50 new crown vaccines have been approved for use in the world, which is also very rare in human history
.

Go back to science and think more

Question 1: Before the epidemic was released, the media reported that 90% of the infected people were asymptomatic infections, but after the release, everyone found that they were surrounded by symptomatic infected people (such as high fever).
Is the asymptomatic that ordinary people understand the same thing as the asymptomatic that professionals say?

Gao Fu: I repeat, the wolf wants to eat sheep, this is ecology, if the wolf does not eat sheep, it will not be able to survive
.
The virus is to infect people, it infects people, it has to continue to proliferate and replicate in your cells, there will be damage to your cells, it will show the symptoms that everyone sees, so it is normal to have symptoms, this is the first
.

Second, what are symptoms? It's called symptom in English, and this symptom is actually the kind of thing
you show differently than you expected.
Is a fever still a symptom? Feeling hoarse in your throat is not a symptom? As long as it is different from normal, it is called a symptom
.
Asymptomatic means that you feel nothing, exactly as
you were.
If you have a fever and you don't want to eat, that's the symptom, and loss of appetite is also a symptom
.

Everyone goes to see textbooks, when the textbooks talk about pathology, the symptoms are loss of appetite, it must be written about the symptoms, and the headache and fever must be symptoms
.
Today, some people say that it is not counted, if it is calculated, it is also called mild disease, is it a mild disease in mild disease, can it be called a mild disease? I personally think that we should not create some useless terms, let it return to science, everyone read more, think more, thank you
.

Question 2: After the yang, how long will the yang return? Are there any rules to follow?

Gao Fu: Now, symptoms and viral load are extremely closely related, when you have symptoms, the viral load will be high, and if you press the virus down, it is the so-called undetectable, but if the course of the disease is long, the virus has always existed, and it will continue to be positive for a long time, or it has not been detected for two days, and it will come out again on the third day, which is not necessarily
.

Fuyang refers to the results of your own naked eye observation, does not mean that the virus is not there, the virus in the process of proliferation and replication, the amount may be different every day, this possibility is there
.
Most people can control the viral load well if they intervene early, such as using specific drugs, early intervention to reduce the viral load, symptomatic symptoms, so that our pain will be reduced, and we can turn negative
in a short time.
