With the emergence of a new variant that has spread to three continents, how terrible is the virus?

<> how terrible this virus really is:

1.This is also evidenced by the contagiousness of Omicron in the Gauteng region of South Africa. In just two weeks, the Omicron variant has tested positive from 1%** to 30%, and the number of cases in South Africa has begun to rise, with 868 cases on Tuesday, 1,275 on Wednesday and more than 3,500 on Thursday.

2.Preliminary research has found that the most worrying thing about Omicron is that this mutant strain has too many mutations. The most interesting mutation of the new crown mutation is the mutation on the spike protein.

The spike protein is the key to the virus's entry into the human body, and mutations on it can allow the virus to bind better to human cells – corresponding to faster transmission, and can also reduce the body's immune memory to the original virus strain, leading to more secondary infections and a decrease in vaccine effectiveness.

3.South Africa's vaccination rate is not high, and the large number of HIV-infected people may be directly related to the new coronavirus variant. Why does a virus strain like Omicron, which has many mutations, appear?

Why is it in South Africa again? South Africa's usual complete vaccination rate is less than 25%, and a large number of young people are not vaccinated, and many cases of Omicron are local young people. Across the continent, overall vaccination rates in Africa range from 7 to 8%.

4.Africa also has a large number of people living with HIV, which means that there are many people with weakened immunity, further increasing the potential risk of mutations in the virus. It is worth pondering that while the complete vaccination rate in the world is close to 43%, the vaccination rate of the African population is less than 10%.

5.Theoretically, the Omicron mutant strain (Omicron) may cause greater hardship to humans, or lead to increased contagiousness and pathogenicity of the virus, but there is not enough data to prove it. After all, the Omicron mutant strain has not been around for a long time, and scientists' understanding of Omicron is still limited.

6.The Omicron mutant strain does have the potential to be a "super strain" and needs special attention, but it is not appropriate to over-interpret the actual harm of this mutant strain, let alone panic. The world is a global village, and villagers must act in unison, and vaccination must reach the same level to stop the spread of infectious diseases, so accelerating vaccination in weak areas around the world as soon as possible is the key to preventing the recurrence of "super strains".

In the same way, in the community, we cannot hope that others will be vaccinated, and we will not do anything while watching the excitement ourselves, and relying on others to build an immune barrier to protect ourselves, which is undoubtedly selfish and stupid.

It's scary because the virus spreads so quickly and it stays in the human body for a long time, so it's scary.

The emergence of the new variant has spread to three continents, indicating that the variant is more infectious and spreads faster. It is likely to become a global virus in the coming months, and there are no obvious symptoms after infection. At present, the medical community is still researching, we must be extremely careful, it is best not to go to high-incidence areas.

This virus is basically out of control now, and it has mutated for several stages, and everyone should still pay attention to wearing masks when going out now. Always wash your hands when you get home.

This time, the virus ** is mainly India, and now the disease in India is very serious, not only hundreds of thousands of people are infected with the new crown virus every day, but also mutant strains have emergedThis has a very big impact on the lives of the Indian people, and it may also have a certain impact on countries around the world, and my country has now seen the emergence of mutant strains, which should also be vigilant.

Now the new crown epidemic has not been completely lifted, because there are still many countries facing the new crown epidemic, and the current situation in India cannot be ignored, many people are infected with the virus every day, and even die. <>

First, the virus is mutating

Mainly because many Indians have been infected with the new coronavirus, and the human body may mutate the virus in the process of resisting the new coronavirus, which is very difficult to mutate.

Moreover, once some viruses mutate, it is very difficult to alleviate people's conditions, and there is no better drug to alleviate them.

The situation in India is critical, with a serious shortage of medical equipment, and many medical staff have no way to help others. <>

Second, add precautionary measures

Although China has now developed a vaccine for the new crown epidemic, and many people have been vaccinated, if the virus mutates, the vaccine that may be vaccinated has no substantial effect.

And for those mutated strains, there is no good way, if it is transmitted, it may cause a large area of people to be infected, making the new crown epidemic serious again.

Therefore, although the current situation in China is still relatively optimistic, we still cannot relax our vigilance, because there is still a certain danger of the epidemic in other countries in the world. <>

And with the strengthening of the globalized economy, every country is very closely connected, and if a country is particularly serious about the new crown epidemic, it is also very likely to endanger the rest of the world.

This time, the virus must be in India, because the mutation of this virus in India and then spread to this place in China, which is really hateful.

I think that the first direction of the virus this time is Southeast Asia, and many people from Southeast Asia have smuggled into Yunnan, China, thus bringing mutant strains into China.

Mutant strains have appeared in many places in China, and the first of the virus is foreign countries like the United Kingdom. African countries.

Previously, 1 case of asymptomatic infection imported from Indonesia was confirmed, 10 cases were imported from India), 1 new case of asymptomatic infection (imported from India), and close contacts who have been screened have been centrally isolated. As of 24:00 on the 28th, a total of 1,343 confirmed cases (124 imported cases) have been reported

It is related to the variant, because for the variant of the new coronavirus, its transmission speed is very fast, and it is highly insidious, and the time for reduction is long, so for a large number of asymptomatic infections, it is related to the characteristics of the variant.

Relate. Because after the emergence of severe mutations of the new coronavirus, the virulence of the variant decreases, but the incubation period in the body is longer, so people will have a series of asymptomatic infections, and they will not show very severe and obvious symptoms in a short period of time.

Asymptomatic infections are basically related to the point of the variant, the transmission speed is too fast, and there are still more strains.

The new mutant strain found in South Africa this time is called Omicron (Omicron), and it is also the most powerful virus found so far, and the World Health Organization (WHO) has listed it as a strain of high concern. There are many things that are terrible about it, but these three things are the main ones.

1. The Omicron virus has a large number of mutations

The reason why Omicron is in the spotlight and is called the "worst" variant is because it has more than 50 mutations, which is twice as many as the previous Delta virus and is currently the most mutated variant. More worryingly, the Omicron variant has both P681H and N679K mutations, which could make the virus more resistant to vaccines.

Second, the Omicron virus is more prone to "reinfection".

Although it is not uncommon for the virus to be "re-infected", such as the cold virus that everyone is already familiar with, but this time Omicron is not simply a cold virus, it will bring harm to the body far beyond the cold, and even life danger.

Omicron is already spreading rapidly in various provinces of South Africa, and similar cases have appeared in various parts of the world. The response now is to reduce travel between countries so as not to spread the spread of Omicron.

Three: The Omicron virus is not easy to detect

What's more, the accuracy of the virus detection for Omicron will be unstable. In other words, if you have already been infected with Omicron but cannot detect it, this increases the risk of carriers sneaking up and may infect more people.

In particular, people who are currently infected with Omicron are generally young in age, and the symptoms are mild, and most people will feel that it is just muscle soreness, skin fatigue, etc., which lasts for a few days. It can be seen that Omicron is better than both Alpha and Delta in terms of its ability to "camouflage" itself.

Judging from the whole body, the new mutant virus Omicron is very powerful, and it is simply the sum of the two viruses Alpha and Delta. But the good news is that our current vaccines still have a lot of effect against Omicron, and those who can afford to get an additional booster dose can also get an additional booster, and wearing a mask is by far the best way to stop contracting the virus.

Therefore, as long as you pay attention to hygiene, ventilate the room, wear a mask when you go out, and do a good job of self-protection, it is the best way to deal with the virus.

The contagiousness is even stronger, and it is important to know that in the tests in various countries, the number of people who have detected this virus has risen sharply, proving that it spreads quickly. As for whether it will cause more serious symptoms, the medical community is still studying, in short, we must be extremely careful.

It's very scary, this virus spreads very fast, and the impact of this virus on people is even greater.

The virus is particularly scary, the virus is particularly contagious, and there are no obvious symptoms at the beginning of infection.

The new coronavirus variant Omicron is highly contagious, and in just over a week, multiple infected people have been found on three continents of the world. The United Kingdom, Belgium, Australia, South Korea, Japan and other countries have taken corresponding prevention and control measures in order to prevent more infection cases, such as Japan and the United Kingdom have carried out a certain scale of "national closure", and the Omicron vaccine is still under developmentIt is still necessary to wear a mask, wash your hands frequently and go out less, especially to reduce non-essential travel.

1. Wearing a mask is still the most effective way

The transmission of the Omicron variant virus is mainly through the respiratory tract, so wearing a mask regularly is an effective way to stop the spread of the virus. Masks should be replaced after a period of use, and masks must be purchased from regular channels. Parents mustEncourage children to wear masks when they go out to school.

Wash your hands frequently when you are at home, and open windows frequently for ventilation.

2. Countries around the world are actively developing vaccines

Omicron has only been around for a week, and many vaccine development companies around the world are already collecting samples of the strain and accelerating the research of vaccine strains of the strain, and it is believed that the results will be available soon. At present, companies such as Pfizer, Johnson & Johnson, Asheng Lizeneca and Sinovac Biotech are focusing on this aspectResults are expected in a few weeks, which can effectively stop the spread of the virus.

3. Reduce the number of people entering and leaving the country

At present, in order to reduce the probability of the people being infected, the United Kingdom has carried out a certain scale of "closure", and no one has been found to be infected with Omicron in mainland China, so my country has issued an appeal to the people to reduce the number of entry and exit, especiallyDo not go to those areas with a high risk of virus transmission, and strengthen personal protection at ordinary times.

The Omicron virus is highly contagious, but it is not impossible to prevent and control it, so we don't need to make it too scary. Usually wear a mask and try to go out as much as possible to reduce the chance of being infected. At the same time, we must wait patiently for the successful development of relevant vaccines, and believe that the Omicron virus will soon be brought under control worldwide.

Prevention and control must be strengthened, disinfection and sterilization must be carried out in a timely manner, and management must be strengthened, so that people infected with these viruses can be isolated immediately and vaccinated.

At present, there is no solution, because the disease came very suddenly, and there is no corresponding test agent and vaccine for the basic barrier, and the corresponding understanding and analysis of the samples are currently being carried out.

We have intensified the intensity of isolation, done a good job in management measures, have been studying the situation of the crushing virus, have done a good job in all aspects of protection, we must protect ourselves, and have been formulating solutions to solve them, and we have searched for new ideas and theories.

We must increase the vaccination rate of vaccines, develop more high-quality vaccines, everyone should do a good job of personal protection, and the country should strengthen control if the slag chain is like a ear to improve the body's immunity.

Controlling the movement of the population and researching a vaccine as soon as possible. The best way to control the spread of the virus is to control the movement of people to avoid the virus spreading too quickly and too widely. There is also the need to develop a vaccine as soon as possible to ensure that the Zhenghe virus can be solved from the root cause of the chaos and strive to minimize the harm of the virus.
