From three years ago to the present, the COVID-19 epidemic has never completely disappeared. The variant bacteria of COVID-19 are still alive, and many regions often cause a new round of infection every two or three months. This is actually like the recurrence of COVID-19, but it is impossible to have a large-scale outbreak. Since the release of the epidemic, nucleic acid testing has stopped in many places. The fear of COVID-19 has disappeared overnight. We no longer see nucleic acid testing and big white workers everywhere. From the fear of infection in the past to the fact that infection is a matter of time, people have accepted it with a calm mind, This means that viruses are no longer scary.
Now the movie box office, snack stalls, service industry and catering industry in tourist attractions have ushered in a peak period of economic recovery, which makes many people think that the virus is like suddenly disappearing. In fact, the virus has not disappeared, and it is also affecting people, but we feel that the virus is like disappearing, so we can only say that the virus itself has a certain transmission coefficient, When it spreads to a certain extent, the virus will become weaker and weaker, which is what we call "transmission is transmission.".
This is the law of the virus itself. When it spreads to a certain extent, it will not fall back quickly, but will stagnate. Just like after the full liberalization of the epidemic, 90% of people in China have been infected with COVID-19. After a large area of infection, everyone has antibodies in their bodies, so the virus will become weaker and weaker, because the national immune barrier has been formed, So now we feel that the virus seems to have disappeared suddenly. The question of whether the COVID-19 has completely disappeared and whether it will return has not yet been answered accurately.
Although we have antibodies in our bodies, the variant strains of the virus have never disappeared. They may be reintroduced from abroad, or new variant strains may be generated in China. In general, the epidemic does not disappear suddenly, but only because few people are infected again after they have resistance, although the number of infected people has decreased, However, COVID-19 has not completely disappeared. On the contrary, COVID-19 has just come to us in another form, just as the current A flow in many regions is a symptom similar to COVID-19.
