html On December 20, Wu Guanying, a famous designer and professor at Tsinghua University Wu Guanying , passed away after being infected at the age of 67.
This reminds me of:
Regarding the current epidemic, these 7 truths are very important but ignored ——
Although the currently popular Omicron strain has a weakened morbidity rate compared with other mutant strains that have been popular in the past, there is still a risk of severe illness and death.
And the risk of severe illness and death will be reflected in all age groups.
- Wang Huaqing, Chief Expert of the Immunization Program at the Chinese Center for Disease Control and Prevention
When the epidemic was first relaxed, many of us mistakenly believed that only young children, the elderly and people with serious underlying diseases were at risk of severe illness and death after infection.
Looking at it now, this is not the case.
Only the 37-year-old Liaoning football coach and the 32-year-old Sichuan doctorate teacher have been exposed by the media. It is not difficult to see:
The risk of severe illness and death is not uncommon among the prime of life.
Yesterday, Wu Guanying, a famous designer and professor at Tsinghua University, died of infection at the age of 67.
Wu Guanying is the designer of the 2008 Beijing Paralympic Games mascot " Fu Niu Lele " and one of the designers of the 2008 Beijing Olympics mascot " Fuwa ".
As Omicron sweeps across China, infecting more and more people and bringing more and more tragedies, our understanding of it is also constantly changing:
Its toxicity is indeed weakening, but it cannot be underestimated at all.
There is a danger of death from infection at any age.
The characteristic of the new coronavirus is that it is not severe when it comes, but it is severe only after 5-7 days of infection.
Therefore, the peak of severe illness will be later than the peak of infection.
In addition, the aggravation of underlying diseases caused by COVID-19 infection also has a time course.
Comprehensive analysis shows that we will see a peak of severe cases in the next one to two weeks.
- Wang Guangfa, Director of the Department of Respiratory and Critical Care Medicine, Peking University First Hospital
Many of my friends and family members only had fever for the first three days after being infected, which was even milder than cold symptoms.
Some people are just lucky and mistakenly think that they are lucky asymptomatic or mildly infected people.
Unexpectedly, the slap in the face would come soon.
After having a fever, which is what Director Wang Guangfa said, within 5-7 days, many people begin to experience uncomfortable symptoms "the nose is sealed with cement, the throat swallows razor blades, and the internal organs are coughed out of the chest".
Vulnerable people with underlying diseases are also at this stage, and they are most likely to be in danger of life.
The 10-year-old girl in Guangxi also died of febrile convulsions on the fifth day of fever.
Director Wang Guangfa’s honest words tell us:
The cunningness of the virus is to start with the minor ones and then the serious ones, so we must not take it lightly.
The peak of serious illness will be one or two weeks after the peak of infection.
The peak of serious illness is the most difficult time for us:
It is about the medical rush, about life and death.
BQ.1 and XBB are new variant branches of Omicron.
Internationally, in some European and American countries, they have shown strong communication advantages.
is mainly characterized by increased transmissibility and immune evasion ability.
However, its pathogenicity is not significantly different from other series of Omicron variants, and the severe disease rate and mortality rate have not been significantly increased.
In the past three months, more than 130 sub-branches of Omicron have been imported into my country, including BQ.1 and XBB.
At present, BQ.1 and XBB have not yet formed an advantageous spread.
but then it will gradually get stronger.
must be vigilant and take precautions.
- Xu Wenbo, Director of the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention
BQ.1 and XBB are two new mutant branches of Omicron, which have demonstrated tornado-like super transmission capabilities in European and American countries.
At present, traces of them have been detected in 9 provinces in my country.
Experts said:
With such a large population base in China, there is a high probability that Omicron will undergo new mutations during its spread.
Why does Academician Zhong Nanshan remind us not to take chances and "take the initiative to infect"?
is because large-scale infection will lead to the emergence of more dangerous mutant branches.
At the end of the documentary "Ten Years of SARS", there is this sentence:
"Although humans have reached the top of the species, viruses were the masters of the earth earlier and are older than human existence.
We don’t know why it came or why it went away. ”
Human beings are really small in front of nature.
There are now multiple subtypes of Omicron strains. After being infected with one subtype, you may be infected with another subtype.
Ultimately it may be like the influenza virus, with seasonal and regional infection characteristics.
After the human body is infected with multiple virus subtypes, under the pressure of immune memory, the virulence of the virus is eventually forced to continue to decrease.
At present, the first batch of vaccine vaccinated by the domestic population comes from the original strain. After the
virus mutates many times, the protective effect of the vaccine becomes weaker and weaker, making it difficult to prevent reinfection with the new coronavirus.
- Director of the Department of Infectious Diseases, Huashan Hospital Affiliated to Fudan University Zhang Wenhong
We must admit:
For a long time in the past, the vaccines provided to us by the state at its own expense have protected us very well.
Until now, vaccines still play an important role as a protective barrier.
However, we must also see the fact that the
virus is constantly mutating, and the protective effect of the vaccine developed based on the original strain against the new mutated virus is indeed weakening.
Saying this is not to underestimate the role of vaccines, but to remind us:
Don’t think that if you let go, if you are infected once, everything will be fine.
Be sure to take precautions to avoid repeated infections.
was positive and then turned negative, and then " positive " was detected. This problem needs to be analyzed in detail.
If after turning negative, the test is positive again, it occurred within one month after "Yang Kang", which is called "recovery of Yang".
"Fuyang" refers to the period of yin and yang caused by the intermittent detoxification of the body.
Don’t be afraid of this. It means that your body’s immunity is recovering and the last viruses are being eliminated.
The original strain in the past had a "recovery" rate of 5% to 15%.
If after turning negative, the test is positive again, it occurred one month after "Yangkang", that is, more than one month, then there is a high probability of repeated infection.
For vulnerable groups, repeated infections are still very harmful.
The "Natural Science" paper shows:
Compared with patients who are only infected with the new coronavirus once, the risk of death for people who are repeatedly infected more than doubles.
are more than three times more likely to develop lung disease and heart disease .
- Based on the discussion of Wang Guiqiang of Peking University First Hospital, Li Tong of Peking University You'an Hospital, Sina News, etc.
, the biggest reminder to us is:
We must be prepared for a long-term fight against new coronavirus pneumonia.
Being infected once is not equivalent to getting a talisman.
Surviving this wave is not equivalent to defeating the virus.
We may have to live with it in the long years to come.
Even so, we should try our best to avoid repeated infections.
Because repeated infections can cause fatal damage to the body.
Currently, we are in the stage of rapid growth of the first round of the epidemic.
As time goes by, the rapid increase in the number of infected people will slow down.
However, after a period of time, with the widespread development of large-scale social activities, including Spring Festival travel or various social activities, there may be a new round of epidemic.
The emergence of such epidemic waves may eventually form a certain herd immunity barrier, and the incidence rate will drop significantly.
- Wang Guiqiang, Director of the Department of Infectious Diseases, Peking University First Hospital
I saw this sentence yesterday:
"I have grown up and have no patience for anything, but the new coronavirus has exhausted me. All the impatience, let me learn to wait. "
In the three years since the epidemic, we have fallen into despair again and again, and have hope again and again. We pray:
"I hope this is the last epidemic. ”
But in reality, it backfires time and time again.
The words of Director Wang Guiqiang remind us again:
After surviving the current wave of infections, we go out of the house and start socializing, and there will be a new wave of infections.
Only by surviving these waves of infections can we obtain herd immunity and start a normal life in the spiraling historical process.
It is inevitable that the new coronavirus will mutate. This is not determined by human will.
Humans are not the only host of the new coronavirus, but many animals are as well.
What is the evolution pattern of the new coronavirus in animals?
We don’t know.
Don’t think that the new coronavirus will definitely become weaker and weaker.
The direction of its variation may be like this in human society, or maybe not.
If some strains that are more susceptible to humans appear in animals, spread faster, and become more pathogenic, we really need to be more vigilant.
In short, we must be realistic about the new coronavirus. We should neither completely underestimate it nor regard it as a scourge.
We must truly understand it scientifically, understand it, and then formulate our strategies. We must not pat our heads or make assumptions out of thin air.
——Wang Guangfa, Director of the Department of Respiratory and Critical Care Medicine, Peking University First Hospital
Before, we saw the view of many experts:
The new coronavirus is getting weaker and weaker, so weak that it will no longer cause a big wave, just like the influenza virus, it coexists with us.
But Director Wang Guangfa’s questionable questioning made us think again:
Everything may not be absolute.
Because all our current energy and research are limited to the spread of viruses in humans, and are far from reaching the animal kingdom.
is like the terrible bird flu . When
is transmitted from poultry to humans, the mortality rate is horrific.
For things that we have not studied or are not clear about, we must be suspicious, reverent, and avoid being arbitrary and lucky, so as to avoid backlash.
Finally, let me share a sentence I learned from reading today:
The past is gone, and the future has not come.
The only miracle we can create now is to survive.
