What can a region do if it wants to achieve herd immunity?

Staying at home, closing the door, really needing to go out, wearing a mask, not physical contact, and maintaining more than one meter of communication is the best epidemic prevention standard.

First of all, there must be a sufficient number of infected people, according to experts, at least 70 percent of the people are infected, and at the same time the infected people develop immunity, so that herd immunity can be achieved.

In this process, it is also necessary to ensure that medical resources are sufficient, and try to avoid the simultaneous influx of infected people into hospitals, resulting in the collapse of the medical system.

Herd immunity can cost extraordinary people lives, so there has been a lot of controversy.

It's very simple, just wait for the vaccine to be injected when it is on the market.

Recently, I saw a very interesting topic, which said that the epidemic situation overseas is very serious, and the number of infected people is very large, although many people will lose their lives because of this virus, but on the other hand, there will be more people who recover from the disease and develop antibodies.

What are the biggest benefits of herd immunity? From a personal point of view, the benefits lie in the following:

First, to a certain extent, China is expected to achieve a herd immunity barrier within the yearThe biggest benefit of herd immunity is that it can avoid the continuous transmission of the virus to a certain extentThis is the most direct and effective, after experiencing the ravages of the new crown epidemic, we have a deep understanding of the rapid spread of the new crown pneumonia virus and the wide range of infectionTo a certain extent, the transmission rate will be faster in public places and in crowded situations, and the realization of herd immunity can avoid the extremely rapid spread of the virus and continuous infection in a short period of time to a certain extent.

Second, it can effectively control the epidemicHerd immunity can effectively control the epidemic and allow the epidemic to be effectively controlled. After all, if people's body functions are protected by vaccines, they can avoid infection and infection to a certain extentWhy is it all in terms of "to a certain extent"? Because the new crown pneumonia is still variable, and most countries in the world are still suffering from the new crown pneumonia, so I dare not and cannot conclude that vaccination can absolutely prevent it.

Third, it has reduced the difficulty of suppressing the epidemicIn terms of the prevention and control of the epidemic, the new crown pneumonia is also very tricky, whether it is foreign rectification or domestic prevention and control, this silent war can last so long, which can also show that the new crown epidemic is indeed not simple, whileThe biggest benefit of achieving herd immunity is that from a medical point of view, it has reduced the difficulty of medical treatment to a certain extent and made it less difficult to suppress the epidemic, then naturally in the new crown pneumonia prevention and control work can be a little more reassuring. But at the end of the day,As long as the epidemic is not over, we must not take it lightly, and we must do a good job of isolation, masks and other related work.

It is very stable, and it can also play a better role in epidemic prevention, everyone has vaccine antibodies, and the new crown pneumonia will slowly not hurt people, so we must actively get vaccinated to protect ourselves and others.

The advantage of herd immunity is that it can reduce the chance of being attacked by the virus, so it will not cause widespread transmission, and we can also open the country.

It can greatly reduce the probability of infection, and all of them can do this, in fact, to ensure everyone's safety.

The biggest benefit of herd immunity is that it allows the population to avoid contracting a certain disease and reduces the risk of disease transmission.

Herd immunity (group immunity) refers to the resistance of a population or livestock group to infection.

A high level of herd immunity indicates a high percentage of animals in the population that are resistant to infection. This is because the likelihood of an epidemic depends not only on the number of resistant individuals in the animal population, but also on the frequency of contact between individuals in the animal population. If 70%-80% of the animals in the population are resistant, there will be no large-scale outbreaks.

As for the biological community, there are two meanings:

In population genetics, it refers to the genetic composition of a population, that is, the frequency of genes and genotypes in this population. For example, the group of pure breeds is homogeneous, and the individuals are homozygous; Whereas, the populations of open pollinating population varieties are heterogeneous and the individuals are heterozygous. The study of population genetic composition in crop breeding is helpful for decision-making of breeding programs.

In terms of crop cultivation, the composition of individual groups of crops grown in the same field is not affected. This individual population may be composed of several crops mixed seeding, intercropping or monoculture, and studying the spatial and phenotypic composition of each individual in the individual population and the coordination of the dynamics between individuals can help guide the cultivation of crops with high yield.

This is a scientific term that refers to the resistance of a population or herd of livestock to contagion. A high population level indicates a high percentage of animals in the population that are resistant to infection. If another 70%-80% of the animals in the herd were resistant, there would be no large-scale outbreaks.

Herd immunity is in layman's termsAfter most people in a group have antibodies to a certain virus, it has a herd immunity effect. Take the new crown virus as an example, one person infected with the new coronavirus will infect 2 3 people, then ifThere are 3 people in a group, and two people must have antibodiesin order to form herd immunity.

Theoretically, if a group of peopleMore than 67%.The number of infected people will be less than 1 person (more than two others have been immune), which will lead to the basic infection number of the virus r0<1, the epidemic will be controlled, and the population will be immune.

First, the majority of the population gains resistance to a certain virus, and then it is used to protect the remaining those who are susceptible to infection.

Because the prevalence of the disease is not calculated by how many immunized people there are in a place, but by the frequency of contact with the population. If the majority of the population is already immune, the chances of the rest of the population getting infected are not very high.

Herd immunity refers to the resistance of a herd to contagion, and in general, 70% to 80% of individuals in a herd are resistant, and there will be no large-scale outbreaks.

Herd immunity is to allow most people to be infected, and then successfully fight the virus or get immune antibodies in people with good immunity.

Everyone is immune, and the virus cannot be circulated.

It's about using vaccines, using vaccines, vaccinating the majority of people in a group.

Most people have immunity, and when it reaches a certain percentage (say 90%), it constitutes an immune barrier, and the pathogen cannot be transmitted in this population.

Vaccines are the safest way to immunize people, and if they are allowed to be infected naturally, they can indeed produce immunity, but it will kill many people, and it may not be able to accurately achieve the minimum immunization ratio required for herd immunity.
