On February 20th, 65438, Wu Guanying, a famous designer and professor of Tsinghua University, died of infection at the age of 67.
This reminds me:
These seven important but neglected truths about the current epidemic-
0 1
People who are seriously ill and dead,
Not limited to the elderly,
Reflected in all ages.
Although the prevalence rate of Omicrovirus has decreased compared with other varieties prevalent in the past, there is still a risk of serious illness and death.
And the risk of serious illness and death will be reflected at all ages.
—— Wang Huaqing, chief expert of immunization program of China CDC.
At the beginning of liberalization, many of us mistakenly thought that only children, the elderly and people with serious basic diseases would face the risk of serious illness and death after infection.
Now, this is not the case.
Only the 37-year-old Liaoning football coach and the 32-year-old Sichuan doctor teacher exposed by the media can easily see:
In the prime of life, the risk of serious illness and death is not uncommon.
Yesterday, Wu Guanying, a famous designer and professor of Tsinghua University, died of infection at the age of 67.
Wu Guanying is the designer of Niu Fu Lele, the mascot of the 2008 Beijing Paralympic Games, and one of the designers of Fuwa, the mascot of the 2008 Beijing Olympic Games.
As Omicron swept across China, it infected more and more people and brought more and more tragedies, and our understanding of it was constantly changing:
Its toxicity is indeed weakening, but it should not be underestimated.
At any age, there is a danger of death after infection.
02
The most difficult obstacle,
Not the peak of infection,
This is a serious peak.
COVID-19's disease is characterized by its severity at first, but it is severe after 5-7 days of infection.
So the severe summit is later than the peak of infection.
In addition, the aggravation of basic diseases caused by COVID-19 infection has a time course.
Comprehensive analysis, in the next week or two, we will usher in a severe peak.
—— Wang Guangfa, Director of Department of Respiratory and Critical Care Medicine, Peking University First Hospital
After many friends and family members around me were infected, they only had a fever for the first three days, and they didn't even get the symptoms of a cold.
Some people are lucky and consider themselves lucky asymptomatic or mildly infected.
Unexpectedly, I was beaten in the face and soon came.
After having a fever, that is, as Director Wang Guangfa said, in 5-7 days, many people began to have uncomfortable symptoms of "sealing cement in their noses, swallowing blades in their throats and coughing up internal organs in their chests".
Vulnerable people with basic diseases are also at this stage, and their lives are most likely to be in danger.
Yesterday, Guangxi 10-year-old girl died of febrile convulsion on the fifth day of fever.
Director Wang Guangfa told us the truth:
The cunning of the virus is that it should be light before heavy, and it must not be taken lightly.
A week or two after the peak of infection is the peak of severe illness.
The peak of serious illness is our most difficult time;
This is a medical race, which is a matter of life and death.
03
Super mutation branch,
Has appeared in China,
It will be strengthened in the future.
BQ. 1 and XBB are new variation branches of Omicron.
Internationally, in some European and American countries, they have shown superior communication advantages.
Mainly manifested in the increase of transmission ability and immune escape ability.
However, its pathogenicity is not significantly different from other series of Omicron mutants, and the severe disease rate and mortality rate have not increased significantly.
In the past three months, more than 65,438+030 Omicron branches have been introduced into China, including BQ. 1 and XBB.
At present, BQ. 1 and XBB have not formed the dominant communication.
But it will gradually increase after that.
We must be vigilant and take precautions.
—— Xu Wenbo, Director of Virus Research Institute of China CDC.
BQ. 1 and XBB are two new branches of Omicron, which have demonstrated the super propagation ability similar to tornadoes in Europe and America.
At present, its trace has been detected in 9 provinces in China.
Experts said that China's population base is so large that it is very likely that Omicron will have new mutations during its spread.
Why did Academician Zhong Nanshan remind us not to "actively infect" with luck? It is because large-scale infection will lead to more dangerous branches.
At the end of the documentary "Ten Years of Sacrifice of SARS", there is such a sentence:
"Although human beings have reached the top of the species, the virus is the owner of the earth earlier and older than human existence.
We don't know where it came from or why it went. "
In front of nature, human beings are really small.
04
The virus is mutating,
The protective power of the vaccine is weakened,
We are in danger of repeated infection.
At present, there are many subtypes of Omicron virus strains, and after one subtype is infected, it may infect another subtype.
It may eventually have the characteristics of seasonal infection and regional infection like influenza virus.
After people are infected with many virus subtypes, under the pressure of immune memory, the virulence of the virus is finally forced to decline.
At present, the first batch of vaccines vaccinated by the domestic population comes from the original strain.
After repeated mutation of the virus, the protective effect of the vaccine becomes weaker and weaker, and it is difficult to prevent COVID-19 from being reinfected.
—— Zhang Wenhong, Director of Infectious Diseases Department of Huashan Hospital affiliated to Fudan University.
We must admit that:
For a long time in the past, the country vaccinated us out of its own pocket, which protected us well.
Until now, vaccines still play an important role as a protective barrier.
However, we should also see the fact that:
The virus is constantly mutating, and the protective effect of the vaccine developed according to the original strain on the new mutated virus is indeed weakening.
This is by no means to underestimate the role of vaccines, but to remind us:
Don't think that if you let it go and get infected once, everything will be fine.
Be sure to do a good job of protection to avoid repeated infections.
05
Repeated infection,
This is very harmful,
Stay alert.
After Yang turns to Yin, it is detected as "Yang". This problem should be analyzed in detail.
If it is positive again after turning negative, it happens within one month after "Yang Kang", which is called "Fuyang".
"Restoring Yang Qi" refers to the imbalance of Yin and Yang caused by intermittent detoxification of the body.
Don't be afraid of this, it means that your immunity is recovering, and you are clearing the last virus.
The "recurrence" rate of previous original strains was 5% to 15%.
If it turns negative and is tested positive again, it happens one month after "Yang Kang", that is, more than one month, then the high probability is repeated infection.
For vulnerable people, the harm of repeated infection is still great.
Natural science papers show that:
Compared with patients infected with COVID-19 virus only once, the risk of death from repeated infection is more than doubled, and the possibility of lung disease and heart disease is more than tripled.
—— Comprehensive Peking University First Hospital Wang Guiqiang, Peking University You 'an Hospital Dong Li, Sina News, etc.
The biggest implication of this discussion is:
We should be prepared for a long struggle with COVID-19.
Being infected once does not mean getting the amulet.
Surviving this wave does not mean defeating the virus.
In the long years to come, we may all get along with it.
Even so, repeated infection can be avoided, but it should be avoided as much as possible.
Because repeated infections can cause fatal harm to the body.
06
Everyone,
Everyone should be mentally prepared,
Facing the ups and downs of the epidemic.
At present, we are in the stage of the first round of rapid epidemic growth.
As time goes on, the number of infected people will increase, and the rapid upward trend will slow down.
But after a period of time, with the extensive development of large-scale social activities, including Spring Festival travel rush craze or various social activities, a new round of epidemic may appear.
The appearance of this wave-like epidemic may eventually form a certain group immune barrier, and the incidence rate will drop significantly.
—— Wang Guiqiang, Director of Infectious Diseases Department of Peking University First Hospital
I saw this sentence yesterday:
"I have no patience for anything since I was a child, but COVID-19 exhausted all my patience and taught me to wait."
During the three years of the pandemic, we fell into despair again and again, hoping and praying again and again:
"I hope this is the last epidemic."
But in reality, it backfired again and again.
Director Wang Guiqiang's words remind us again:
Get through the current wave of infection, go out of the house and start socializing, and there will be a new wave of infection.
Through this wave after wave of infection, we can gain group immunity and start a normal life in the spiral historical process.
07
For the unknown,
Be awed,
Not arbitrary.
It is inevitable that COVID-19 will mutate, which is not determined by human will.
Humans are not the only hosts of COVID-19, and so are many animals.
What is the evolution law of COVID-19 in animals?
We don't know.
Don't think that COVID-19 will get weaker and weaker.
Its variation direction may or may not be like this in human society.
If some strains that are more susceptible to humans appear in animals, they will spread faster and be more pathogenic. We really need to be vigilant.
In a word, we should treat COVID-19 realistically, and we can neither completely despise it nor treat it as a scourge.
Really understand it scientifically, know it, and then formulate our strategies to avoid patting our heads and speculating out of thin air.
—— Wang Guangfa, Director of Department of Respiratory and Critical Care Medicine, Peking University First Hospital
Before, we saw the opinions of many experts:
COVID-19 is getting weaker and weaker, so weak that it won't cause any more big storms. Just like the flu virus, it is with us.
But director Wang Guangfa's questioning made us think again:
Everything may not be absolute.
Because all our energy and research at present are limited to the spread of the virus in humans, far from the animal kingdom.
Just like the terrible bird flu.
When it spreads from birds to humans, the mortality rate is very terrible.
For things that have not been studied or are not clear, we should be suspicious and awe-stricken, and avoid arbitrariness and luck to avoid being reviled.
