Significance of the Virus Coexistence in Post-epidemic Era
We all expect to purify the virus, just as smallpox virus disappearing, but the fact tells us that it is difficult to do so. Over the years, we have observed the spread and process of viral diseases in the animals’ community and cluster infection. Unless the virus has a single host and we have effective prevention and control methods, it is difficult to remove the virus, which also means that the virus will continue to spread in the cluster, because the traditional methods of virus prevention and control can not avoid the dissemination and spread of the virus. Therefore, the significance of peaceful coexistence with viruses does not lie in how to eliminate viruses, but in:
(1) Reduce the speed of virus spread: You can have time to deal with it so that the amount of medical treatment can not be overwhelmed.
(2) Reduce the impact of virus on individuals: Reduce the chances of moderately severe disease and death.
Mucosal immunity just can get these two points: Mucosal immunity, the IgA produced can neutralize the virus in the mucosa, which is equivalent to help us wear one more mask, which can effectively prevent viral infection and reduce the risk of infection. If people unfortunately infect COVID-19, it can also shorten the course of the disease, recover quickly, and can not turn into severe disease and die.
From the above concepts, mucosal immunization is helpful for people in terms of how to coexist peacefully with the COVID-19. It may not be subject to any restrictions for infected people in the future. At present, whether it is isolation or vaccination, it seems that it is still impossible to control dissemination and spread of the virus. Therefore, when people are PCR-verified and when the positive-verified turns negative will no longer be the focus of people's concern. Thus, the focus should be on reducing the impact of the virus on the human body, which is also what mucosal immunity can do because mucosal immunity can alleviate or relieve the symptom response after infection in a short time. If the symptoms can be relieved in a short time, it means that it will reduce the chance of turning into severe disease. Isn’t this the result that everyone wants to coexist with the virus?
