Although the Omicron strain has just emerged, more than 90% of new cases in the United States are caused by mutations of this virus, which shows how contagious it is.

Recently, a new mutated virus has emerged, doubling the pressure on various countries.

Although the Omicron strain has just emerged, more than 90% of new cases in the United States are caused by the mutation of this virus, which shows how contagious it is.

French media stated that the national scientific research department discovered a new type of virus in the new coronavirus at the end of 2022.

According to relevant information, the virus has as many as 46 mutation sites, so it is called "IHU" internationally.

However, due to the lack of understanding and research on this virus, its contagiousness and transmissibility are still unclear, so WHO included it as a strain that needs to be monitored.

The current situation in our country

In recent times, the country has made corresponding adjustments to the control of the epidemic to ensure economic and social development.

But this does not mean that we do not care about the situation of the new coronavirus.

Unconsciously, the new coronavirus has "accompanied" mankind for nearly three years.

In the past three years, mankind has been engaged in a desperate struggle with the new coronavirus.

In the past three years, the new coronavirus has also undergone various mutations and tried to "coexist" with humans.

In fact, on December 20 this year, the Joint Prevention and Control Mechanism of the State Council released an important news, that is, mutations of the Omicron virus have appeared in many places.

According to the survey, the harm of the new coronavirus to humans is currently weakening, so our country has begun to fully relax the epidemic.

But when the virus was first released, many people were infected, and some mutant strains also emerged.

Xu Wenbo, director of the Virology Department of the Chinese Center for Disease Control, recently stated: There are more than 130 sub-branch species in China, among which BQ.1 and XBB are the two most recent variants.

It is reported that BQ.1 and XBB are new variants of the Omicron virus, which have shown the characteristics of their dominant strains in Europe and the United States. The main characteristics of

are high infectivity and high immune evasion, but its infection rate and mortality rate are still very low.

related survey data shows that although BQ.1 and XBB have not yet formed an "advantage" in China, their communication advantages will gradually strengthen and may form a vicious cycle with the input of sub-branches such as BF.5.2 and BF.7.

Therefore, we still need to strengthen our own prevention and control to control the spread of the virus from the source.

However, the current pathogenicity of these variants is not significantly different from Omicron , and its main manifestations are transmissibility and immune evasion.

Because the mortality rate of Omicron is 0.1%, and after being infected for the first time, his body will produce antibodies, so there is a saying in many places that "it is better to get the vaccine than to be infected with Omicron once."

In fact, Academician Zhong Nanshan already responded to this issue at the "National College Student Anti-epidemic Lecture" on December 15.

He said: The mentality of everyone being positive together is not advisable. If it spreads on a large scale in such a short period of time, it will not only have a certain impact on human security, but may even cause new viruses.

Recently, a variant of the new coronavirus, such as delta strain , has been circulating on the Internet and has become popular in Beijing.

There is also a "conclusive" message, saying that "Wang Guangfa, an expert who previously supported Wuhan at Peking University , believes that the new coronavirus that appeared in Beijing is not the Omicron virus, but the Delta 7 mutant strain." This incident caused panic in public opinion.

Soon, Pan Yang from the Institute of Infectious Disease Prevention and Control of the Beijing Center for Disease Control and Prevention responded to this “conclusive” news.

In the past two months or so, the new coronavirus in Beijing has been mainly composed of Omicron mutant strains BF.7 and BA.5.2 branches. No mutant strains such as XBB and BQ.1 have been found, and no non-Omicron mutant strains such as the original strain and delta have been found.

my country has now discovered more than 130 virus strains of 9 subtypes

The same strain still has strong neutralizing antibodies in the short term and will not cause further infection.

Different viruses, due to differences in antibodies in the body, can lead to repeated viral infections.

This is currently a generally accepted conclusion in domestic medicine.

Therefore, Academician Zhong Nanshan also believes that there is no need to panic excessively. We must strictly abide by the epidemic prevention and control measures and do a good job in our own protection.

Three things should be done urgently:

1. Call on the whole world to work together to strengthen scientific disease prevention, precise prevention, and defeat the epidemic.

2. Further strengthen research on drugs to treat the new coronavirus.

3. herd immunity is achieved by the vaccination of new crown vaccine , so everyone should actively inject the vaccine, especially the booster injection.

Zhong Nanshan’s reminder is very important

Some cities, such as Chengdu, are at the peak of the outbreak.

At present, some residents in Chengdu have returned to negative after being infected, and some have begun to return to work. However, some people are still infected.

The Chengdu Health Commission calls on the general public to take personal protection. People who have not been infected should try to avoid being infected by the new coronavirus and try to be infected by the new coronavirus as soon as possible.

However, some people believe they have been infected once and are therefore not concerned about a possible or imminent outbreak.

In fact, there are many main variants of Omicron virus, and the mutation position of each subtype is different. Human beings currently do not have the ability to establish an immune barrier for every virus. Therefore, even recovered patients are still at risk of " secondary infection " and "multiple infections."

Now our main energy is focused on the prevention and treatment of severely ill patients, but we must also pay attention to preventing infection, especially the elderly and vulnerable groups. They are our key protection targets and our main target.

Does repeated infection with the new coronavirus increase the mortality rate?

Research shows that the mortality rate of repeated COVID-19 infections is more than twice that of initial infections.

In fact, this conclusion is easy to explain. Once infected, our body will lose most of its resistance . Before it can fully recover, it will be infected again. Naturally, our body's immune system will collapse over time.

Therefore, researchers remind people who have been infected with the new coronavirus not to relax and to stay alert at all times to reduce the chance of reinfection.

This new type of coronavirus continues to evolve and may pose a threat to us humans in the next few years or even decades.

Conclusion

In short, with the spread of the epidemic, medical resources are in short supply. After being infected with new crown , you must make your own adjustments and treatments, do your own physical health testing, and reduce the risk of other diseases.

We should pay attention to developing good work and rest habits in daily life, go to bed early and get up early, stay up less late, sleep for 8 hours, and exercise more to improve the body's immunity .

In daily life, we must also pay attention to personal and environmental hygiene, balanced nutrition, proper exercise, adequate rest, avoid overexertion, wash hands frequently, and wear a mask when going out.

Now that the Spring Festival is coming, don’t eat and drink too much just for the so-called face, gathering with relatives and friends.

After all, good health and safety are what we should pursue most.

It’s almost the Spring Festival, will you have dinner together? Have you taken any precautions against the epidemic?
