Why is COVID-19 listed as a first-level response?

1. First of all, it must be for the personal safety of ordinary people. At first, because the pulse of this virus is not clear, the harm is still relatively large, and the mortality rate is still relatively large. Therefore, strict prevention and strict treatment must be taken. However, after three years, we have fully understood the principle of this virus. Most people have been vaccinated with COVID-19 vaccine, and the harm of the virus has gradually decreased, but it still does harm to human body, and it still needs prevention, control and treatment.

2. The second reason is that the existing Omicron strain has many characteristics, such as strong infectivity, wide spread range, fast spread and strong concealment. Once spread, it may lead to large-scale and large-scale human infection. Once a large number of people are infected, more medical equipment and more medical personnel are needed to treat these patients. But in the face of the sudden surge of patients, our normal hospitals and medical staff are not enough. Therefore, if a large-scale epidemic breaks out, it is very likely to cause a medical run. If some people can't get timely and effective treatment, they are likely to lose their lives or cause serious injuries.

3. Although the incidence, severity and mortality of Omicron are decreasing, the infection rate is still very strong and hidden. In this case, it is inevitable that all kinds of people will get seriously ill or even die. Moreover, if someone doesn't know much about the current virus, it may aggravate people's panic, which will lead to the phenomenon of spreading false information and blindly following the trend.
