Since yesterday, news of the sudden emergence of the strain sequence XBB1.5 has flooded the Internet. There seemed to be no news at all before, but it felt like a new big strain suddenly appeared.
I spent a day today looking for all kinds of traces of this XBB1.5 strain in the past month. Now let’s sort it out for you:
. XBB1.5 first appeared in early December. I think the United States should be the first to discover the "hidden power" of this strain.
About half a month ago, I wrote an article specifically about why the United States, out of normalcy, suddenly restarted nucleic acid testing for all residents of the United States.
I estimate that it was at that time that the virology experts in the United States discovered something was wrong. When I wrote the article, I was worried whether the United States had discovered a new virus and what hidden features had?
So, at that time, the United States suddenly restarted the new coronavirus nucleic acid!
, the decision was announced on December 15th, US time. The general meaning of the decision was that COVID-19 testing would be restarted at every address in every household in the United States.
And the White House mails antigen tests to residents in the United States for free! Only one order can be placed per household address, and each order includes test kits for four people.
You must know that before this national nucleic acid test, the United States had been lying flat for more than two years. It had been at least more than half a year since the last national nucleic acid test. .
Therefore, the behavior on December 15th was super, super abnormal!
felt that there was no news. After a few months, the US government suddenly provided free COVID-19 testing to local residents and asked them to get a COVID-19 test!
When things go wrong, there must be a demon!
Today’s facts prove that the United States’ decision at that time was by no means an accident. The newly discovered virus XBB1.5 suddenly appeared. In just half a month,
quickly replaced other virus branches in the past, including the strain code-named Cerberus, which was far inferior to the new virus XBB1.5. The concealment and transmissibility of the
XBB1.5 strain are really too strong! !
3, in addition to suddenly restarting the national nucleic acid test, the United States actually had an abnormal data at that time. Even the number of confirmed cases and deaths in a short period of time has suddenly increased.
I mentioned this in the article I wrote at the time, but because the US official did not give specific figures, I just mentioned it in passing.
Thinking about it now, I was still careless at the time. In fact, reports from ABC News on December 16 should have caused alarm.
At that time, ABC News was one of the few American media to mention that in the past few weeks, the number of cases and hospitalizations of the new coronavirus in the United States suddenly began to rise rapidly.
Both the number of confirmed cases and the number of deaths are increasing rapidly! !
4, in addition to the media, local health officials in the United States should also have known about the powerful concealment, strong transmissibility, and danger of the XBB1.5 strain at that time.
Data shows that starting from December 16, in fact, in order to prevent more residents from being infected and dying, Washington State local county health officials and hospital executives have issued the latest guidance requiring residents to wear masks indoors;
also starting from December 16, the Oregon Health Authority has also issued recommendations! The reason given for requiring residents to wear masks in indoor areas is to protect children and the elderly;
and public health experts in Los Angeles also stated at the time that new submutated strains and lower vaccine booster vaccination rates had led to a surge in the number of infections, calling on people to go indoors and wear masks again.
Therefore, there are still traces of this matter. If you are careful, starting from December 15th, health measures in many areas of the United States and health officials are actually improving epidemic prevention measures.
includes restarting the new coronavirus nucleic acid, including suddenly calling on people to wear masks again. .
You must know that the United States has been removing masks for more than a year, but suddenly in the past half month, health officials everywhere have made the American people suddenly resume wearing masks. . .
One weird move after another shows that the US health agencies and health officials may have known about the severity of the XBB1.5 strain half a month ago! !

5, a new transmission strain has appeared, no matter how much we worry about it, it is useless now. We can only be ourselves, strengthen our own protection in the next month, wear a mask, and try not to be infected by again.
Because the latest data released by the U.S. Centers for Disease Control and Prevention shows that 40.5% of new coronavirus infection cases in the United States in the latest week were caused by the highly contagious Omicron subtype strain XBB.1.5.
In other words, the new strain is highly evasive and will not prevent you from being infected again just because you have been exposed to Omicron before.
According to the current transmission situation in the United States, American residents newly diagnosed with the XBB.1.5 strain have also been infected with other strains of Omicron before and have antibodies! antigen !
However, antibodies and antigens did not prevent the spread. Among the people diagnosed in the United States in the new week, at least more than 40% were infected with XBB.1.5.
6, although the international gene sequence for XBB shows that it still belongs to the subclade of Omicron and is a recombinant variant strain of the variant strain below BA.2.
However, it only took half a month to kill all the new coronavirus strains in the United States. The intensity of the infection is completely different from its predecessors.
It has extremely powerful immune evasion ability! ! Unlike other subclades of Omicron in the past, once you are infected once, you will not be easily infected with other subclades of Omicron again.
XBB.1.5 will escape our body's immune system . Simply put, it will cause secondary infection! At least so far, it is the strain with the strongest secondary infection ability among all known new coronavirus strains in the world.
This is actually the situation in the United States now. After more than two years of lying down, everyone in the United States already has antibodies and antigens.
But scientists found that this is not the case; half a month ago, the White House in the United States issued nucleic acid tests to all people. After the test, it was found that many, many people were infected twice. More than 40% of the people are infected with XBB.1.5! !
Therefore, I said that in the next month, we must take precautions. Don't be careless just because you have passed Yangkang Road.
Nowadays, secondary infections have begun to spread in some foreign areas, including the United States, and they are all caused by XBB.1.5, so we cannot take it lightly.
7, on the toxic power of XBB.1.5. In addition to the powerful escape ability, secondary infection ability, and transmission ability mentioned above; other characteristics of
are currently mentioned most online, including the possibility of causing diarrhea, and the discovery that XBB1.5 is more likely to invade the cardiovascular and cerebrovascular systems.
Therefore, since yesterday, everyone has started to grab a lot of medicines on the Internet, especially various anti-diarrheal medicines.
Including montmorillonite powder for children to relieve diarrhea, and and norfloxacin for adults to relieve diarrhea, all are being grabbed.
Regarding these, I won’t add much. Just listen to the doctors and experts. Let me remind you: remember that norfloxacin can only be used by adults, and try not to give it to children.
Norfloxacin is too strong and not suitable for children.Taking too much will affect the child's bone development and hinder the child's height, physical growth and development! ! You must remember. .
8, the most important thing is that after January 8th, you must take precautions.
Because according to the latest news from the country, starting from January 8, 2023, China will officially open its doors.
That is to say, starting from January 8, a few days later, in accordance with the latest Border Health and Quarantine Law, quarantine measures for infectious diseases will no longer be taken for incoming personnel and goods.
Therefore, if nothing unexpected happens, after January 8th, XBB.1.5 will basically flood into our side. Unless we do not open the country, otherwise after liberalization, these will not be avoided.
In fact, sporadic cases of XBB family have been discovered in Shanghai.
The Paper is actually already making early warning reports, based on the latest data added to the Global Initiative for Sharing All Influenza Data (GISAID) database.
We in China have recently added 369 new coronavirus sequencing results in China. The uploaders are Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine A joint scientific research team led by Chen Saijuan and Fan Xiaohong of Shanghai Public Health Clinical Center.

These samples were all from COVID-19 patients in the Shanghai area. They were randomly collected from November 23 to December 22 this year. After gene sequencing confirmed the BQ.1 family that is currently widely popular in Europe and the United States, which is the Cerberus you heard, and the XBB family you heard about today.
Do you know how much the two together account for? More than a third! !
In other words, according to Shanghai data, XBB has already arrived in Shanghai.
The current monitoring data is that 25 cases of XBB family patient strains have been detected in Shanghai this time.
Among them, 3 cases are the most powerful XBB.1.5 strain in the world. . .
Therefore, friends in Shanghai should pay special attention to safety and pay attention to protection in the near future! You may be one of the first big cities to face the impact of XBB.1.5!
9, let me finally show you a picture of the proportion of each strain tested for the new coronavirus in the United States half a month ago.
Today’s big strain, XBB.1.5, was just a little bit of the coronavirus in the United States half a month ago.
At that time, the most popular product was the BQ.1 series. The total proportion of the top two BQ.1 families together exceeds 60% of the United States!
At that time, XBB had just emerged, accounting for only about 5%.
Who would have thought that in just half a month, the XBB family could sweep across the United States and swallow up the territory of all other strains. .
Nowadays, a new large strain of XBB.1.5 has appeared in the XBB family; it has excellent escaping and transmissibility, so this winter, all of us must be more vigilant, and we cannot be careless just because you have already passed by.
Sheep had to endure torture such as swallowing a razor blade in her throat, having a high fever, coughing, and a runny nose.
The next XBB.1.5 second infection, I really don’t want to be infected again. Especially if you are unlucky with this strain, you will have diarrhea, and it will feel like an explosion, which is really uncomfortable. .
Don’t take any chances. The latest week’s data in the United States clearly states that more than 40% of confirmed cases are caused by XBB.1.5.
According to the data that the United States has already surpassed the number of sheep per capita, the large number of infected people now must be secondary infections. .
Everyone, please continue to protect yourself, the gate of heaven will open in 5 years!
After the country reopens, we will protect ourselves and try not to be infected with XBB.1.5 in the first wave. We will wait for the temperature to rise after a month!
No matter how dangerous the large strain XBB.1.5 is, it can’t hurt you or me! !
The most rare thing in life is to be "sober in the world"
A master is profound and relaxed, while a mediocre person is superficial and painful!
