Why should we fully liberalize it? It is because the Omicron strain is no longer preventable and can only coexist with the virus through universal immunization.
But the speed of virus mutation seems to be accelerating, and it is becoming more and more cunning.

In the past two days, a piece of news quickly appeared on the hot search lists of major platforms, that is, XBB.1.5 has become the "number one popular strain" in the United States.
According to data from the US Centers for Disease Control and Prevention , XBB.1.5 has spread rapidly in the United States. In the past week, the proportion of infections has accounted for 40%, an increase of 20 percentage points from the previous week. It is likely to sweep across the United States and spread around the world.
So what kind of virus is XBB.1.5? According to genetic sequencing, XBB.1.5 is still a variant of or micron . But the biggest feature of this new strain is its ability to better bind to cells.
To put it simply, XBB.1.5 is more contagious than Omicron.
Everyone should still remember the contagiousness of Omicron! Since my country's full liberalization on December 7, in more than half a month, Omicron has basically swept through the entire China from east to west and from north to south.
According to data published by some provinces, the actual infection rate in Sichuan should reach 80%. The situation in Beijing and Sichuan is similar, and it is estimated to be about 80%. In Hainan, it is about 50%, and in Zhejiang, it is about 40%.
Some provinces and cities are still at the peak of the first wave of infection.

Omicron spread so fast, although it caused great panic to people across the country in a short period of time, there are pros and cons to everything. The infection rate in the first wave of is so high, which will still have a positive effect on the establishment of the national immune system and the impact on the second wave infection rate. Although
still has a certain secondary infection rate, after all, it is not easy to be infected again by the same virus in the short term.
However, after the attack of XBB.1.5, it became more contagious than Omicron. International experts agreed that the new strain will become the main force of global spread in the future. So what is the situation in the country?
According to the test results in Shanghai, among the recently infected people in Shanghai, the "southern strain" BA.5.2 and the "northern strain" BF.7 of Omicron through gene sequencing are mainly the ones, and no new mutant strains have been found yet.
However, we still cannot take it lightly, because according to the latest monitoring results of Shanghai Jiao Tong University School of Medicine , 25 cases of infection in the XBB family have been found, 3 of which are XBB.1.5. They are all closed-loop transfer personnel of imported cases from abroad, and have not caused local transmission.
However, according to the news previously announced by our country, starting from January 8, the prevention level of the new coronavirus will be lowered to a Category B B infectious disease. At the same time, entry and exit management will be fully liberalized, and centralized isolation will no longer be adopted.
Therefore, it is inevitable that XBB.1.5 will flow into China on a large scale.

So the question is, will XBB.1.5 cause a large area of domestic to be infected with again? After all, people across the country have just had a fever, and they are still in the immunity period. XBB.1.5 is so contagious, is it possible that everyone before was infected in vain?
According to the opinions of some domestic experts, it is currently unclear whether people infected with Omicron will be infected with XBB.1.5 in the short term. It still depends on how much overlap the two viruses have, and it also has a certain relationship with the body's resistance .
shows that we are still determining the true situation of this virus, and the probability of secondary infection is still unclear.
But one thing is certain, that is, the pathogenicity of XBB.1.5 is equivalent to that of Omicron, or even weaker.
Before everyone was panicking, it was mainly caused by the lack of medical treatment and lack of medicine. After more than half a month of increasing production capacity and , the supply of antipyretic and cold medicines has basically resumed to meet the daily needs of the people.
Some people believe that since XBB.1.5 is more contagious, should we open the country later, or return to the anti-epidemic path of dynamic clearing and lockdown? The view of
is obviously wrong. is already unstoppable because of Omicron. XBB.1.5 is more contagious and cannot be dynamically cleared.

Fortunately, the pathogenicity of the virus has not increased, and foreign countries have been open to the virus for a long time. There is also a certain proportion of repeated infections. Most people have become accustomed to it, just like a cold.
So you don’t have to worry too much about XBB.1.5.
On New Year’s Day this year, cities such as Beijing, Shanghai, and Wuhan that successfully passed the peak of the first wave of the epidemic have resumed their former bustle. This is the hope of life.
