If the epidemic is intervened manually, will all human beings theoretically be infected?

If the epidemic is intervened manually, theoretically all humans will not be infected。Although this virus is very contagious, it still takes a certain amount of time to infect all human beings, after all, the number of all human beings is very large, and without intervention, it is impossible to infect all people for at least a year. Now, after China has strengthened prevention, the number of infected people has been controlled at about 70,000 in two months, which means that if there is no prevention, the number of people who may be infected in China will be 100,000 more.

However, China has a total population of 1.4 billion, and if there is no intervention in two months, about 200,000 people may be infected, and if we look at this rate, the number of people infected in China will not exceed 100 million in a year. But the time left for the virus is not that long, the virus is relatively active in the winter, and it will not be killed, but once it enters the summer, the temperature rises, and these viruses are difficult to survive.

Therefore, even if the infection is more severe in winter and spring, once it enters summer, the activity of these viruses will decrease, the infectivity will also decrease, and most viruses will also be exposed to ultraviolet rays.

killed. Because there are two main conditions that can kill bacteria at present, the first is high temperature, and the second is time, and these two conditions can be achieved at the same time in summer, so the virus will die in summer, and human beings will also get a chance in summer.

Even if there is no human intervention, hundreds of millions of people around the world will be infected, but the mortality rate of this disease.

It's about five percent, so people who are unlucky die, but those who survive get antibodies, and they become immune to the virus and won't get reinfected. Therefore, it is impractical to infect all human beings, after all, there are too many human beings.

In fact, there have been large-scale epidemics in history, and the level of medical care was too low for human beings at that time, and there was almost no human intervention. Although these epidemics caused many deaths, in the end, humanity survived, which shows that it is impossible for the virus to infect all humans in a short period of time.

Of course, this is not the case, which means that human beings have done a lot of things with their own bodies. Then it is a terrible thing to do to make the virus spread faster, but there is no way to stop it, it can only be done like this.

Probably, if some countries with ill intentions want to use the epidemic to do something, then it is very good that all mankind will be infected!

The epidemic can only be suppressed and alleviated by human intervention, because the virus has a limited survival time and is in the form of human-to-human transmission, and if there is less contact between people, then the virus will inevitably be defeated.

Theoretically, all human beings would be infected, and no one would cure the disease without intervention.

No, because there are still very backward places on the planet that are inaccessible and isolated, and the virus can't spread there at all.

The best way to prevent a widespread epidemic of infectious diseases is to protect susceptible populations, and vaccination is currently the best way.

Planned immunization is the application of the principle of immunology, according to the epidemic monitoring of diseases and the characteristics of children's immunization, the formulation of scientific immunization procedures, the planned and organized use of vaccines for vaccination, so as to improve the level of population immunity, to achieve the purpose of controlling and eliminating the corresponding diseases. Artificial immunity is based on the principle of natural immunity, using artificial methods, so that the human body to obtain specific immunity Artificial immunity is widely used in the prevention of infectious diseases, but also used for some infectious diseases.
