Under the situation that the epidemic situation in the world is tense, but it tends to be stable in China, the delta virus is not idle

.

It attacked Guangdong and hit Guangdong hard two months ago, but China’s largest economic province, united as one, pushed it back

.

Two months later, it finally found the flaw of the great wall of China’s national defense epidemic and took a plane from Moscow The magic flight, which has repeatedly dissolved and poisoned, tore a hole in the blood forest at Lukou Airport in Nanjing

.

Different from the previous epidemic, this epidemic is a variant virus delta that scares the world

.

After breaking through the defense line of Lukou Airport, Delta has “attacked the city and pulled out the stronghold” all the way and has spread all over n provinces and N cities (the increasing epidemic notification makes it impossible for the science editor to tell how many provinces and cities have been infected)

.

But one thing is certain

.

Almost half of China’s provinces have been captured

.

Since July 20, 220 cases have been confirmed in Nanjing in only half a month

.

What’s more terrible is that all confirmed cases have appeared from Inner Mongolia in the north to Hainan Province in the south

.

When many of us thought that we had been vaccinated and COVID-19 was no longer terrible, delta gave everyone a lesson

.

Nanjing Lukou Airport communication chain, Zhangjiajie communication chain, and then Changde cruise ship communication chain..

.

The communication speed and intensity of delta are beyond everyone’s expectation

.

From Nanjing at the beginning to the two communication centers formed in Zhangjiajie later, there was a “spectacular” scene of queuing up for nucleic acid and vaccination in many provinces and cities in China

.

Since Guangdong was badly hit two months ago, now Nanjing and Yangzhou are heavily occupied, and Jiangsu, the second largest economic province, is in danger! How many minutes of sex do you pass? Click here to have a look! July siege, a prophecy, Yangzhou lesson, sad! On August 2 alone, 40 cases were newly diagnosed in Yangzhou, which has always been stable

.

So far, a total of 94 cases have been diagnosed in Yangzhou

.

On August 3, the main urban area of Yangzhou implemented closed management for all residential areas except closed residential areas

.

This means that the whole main urban area of Yangzhou has been shut down since then

.

On the same day, Zhangjiajie announced that all residents and tourists were not allowed to leave Zhangjiajie

.

All offline education, teaching and gathering activities such as make-up classes for junior and senior high school graduation grades, research travel, freshmen military training, training in private education and training institutions in Wuhan have been suspended! A year and a half ago, it seemed that the scene that we all feared would appear again

.

Good China, why such a passive situation? How selfish can an old man be? These two days, 1.4 billion Chinese have seen it thoroughly! On July 20, an epidemic occurred at Lukou Airport in Nanjing

.

At 8:20 a.m

.

on July 21, Nanjing controlled key epidemic related areas at different levels

.

The local personnel in charge of control in Nanjing did not expect that a 66 year old woman in a key epidemic area successfully got on the bus to Yangzhou at 9:00 after being controlled

.

When he arrived in Yangzhou, the old man was not afraid of the potential transmission risk

.

He went not only to restaurants and shops, but also to barber shops, completely unaware of the seriousness of the matter

.

What makes everyone feel hateful is that we can see from her track of action that she has had the experience of repeatedly buying drugs before

.

This means that before the diagnosis, old lady Mao had novel coronavirus symptoms and tried to suppress them

.

Her psychological quality was excellent

.

She didn’t panic because of her own symptoms, but shuttled through the chess and card room for many days

.

be careful! This is not an ordinary chess and card room, but a chess and card room transformed by the supermarket

.

Hundreds of mahjong tables are stacked together

.

Most of them are middle-aged and elderly people with weak awareness of epidemic prevention

.

The spectacular picture is unimaginable

.

Knowing that he came from a high-risk area, he still went to Yangzhou without authorization; Knowing his yellow code, he didn’t isolate on the spot, but ran all over the streets and alleys of Yangzhou; Knowing that he had a fever, he did not report it in time, but borrowed his family’s green code to see a doctor; Knowing that his nucleic acid was positive, he did not cooperate with the investigation, but savagely opposed the medical staff

.

Sure enough, a large number of confirmed cases have a common activity track – playing mahjong

.

At present, the Yangzhou epidemic caused by Mrs

.

Mao’s concealment of her itinerary has been filed

.

Once she sits down, she will face 3 to 7 years in prison

.

Not only because of her escape and concealment, but also to give a warning to others who hide their itinerary

.

Everyone should be responsible for their actions

.

The elderly will not escape the punishment of the law because of their age

.

Everyone is equal before the law! Learn from the lesson of old lady Mao

.

Today, when the epidemic has not completely dissipated or even intensified, do you really push your compatriots into the abyss of pain and death for your temporary happiness? Recently, it came out that the Pulitzer Prize reporter was killed by the Taliban

.

His name is Danish Sidiki

.

It doesn’t matter if you don’t know him, but you must know the photos he took: every Chinese should remember that the delta virus raging in India can never be allowed in China! Every Chinese is facing great risks! There are only two weapons against risk: vaccines and masks

.

There are only three ways to resist risk: less parties! Novel coronavirus specific drugs are expected to appear, and they are effective for Delta? On August 4, Sinopharm China biology official micro posted that recently, Sinopharm China biology researcher Yang Xiaoming team recently found an effective monoclonal antibody against delta mutant strain, with neutralizing activity IC50 as high as 5ng / ml

.

In novel coronavirus pneumonia, Delta is a new effective gene for the treatment of novel coronavirus strains

.

According to public data, monoclonal antibodies, as targeted therapeutic drugs, have the characteristics of strong specificity, significant curative effect and low toxicity

.

They are known as “biological missiles”, and show excellent curative effect and broad application prospects in the treatment of a variety of diseases

.

In the treatment of viral infectious diseases, neutralizing monoclonal antibodies can not only serve as short-term prevention for high-risk groups, but also can be used for the treatment of viral infections

.

Therefore, it is also a hot topic in global COVID-19 prevention and control research

.

In addition to increasing the intensity of nucleic acid screening and popularizing vaccination, the development of effective drugs should be the most valuable “ultimate weapon” for the COVID-19 mutant

.

According to the 21st Century Business Herald, in this study of Chinese medicine, phage display technology was used to successfully screen a number of monoclonal antibodies with high and activity against sars-cov-2

.

The crystal structure analysis data show that the RBD epitope recognized by the most active antibody 2B11 is highly overlapped with the binding site of ACE2, which can effectively block the binding of COVID-19 to the ACE-2 on the cell surface, thereby preventing its infected cells

.

The use of 2B11 can significantly reduce the lung inflammation caused by virus infection

.

At present, the clinical declaration of the 2B11 antibody is being carried out in an orderly way so as to be used as soon as possible for the prevention and control of COVID-19 in China

.

This study is expected to become a powerful weapon to deal with the mutant strains

.

Under the research results that the mAb is effective for Delta and other novel coronavirus mutant strains, it is expected to further improve the market capacity of mAb drugs
