The reason why the students in Dalian University Town collectively shouted for Zhuanghe to come on is mainly because there were many infected things in Dalian University Town during this epidemic spread, so the University Town is now in a closed state. I think the practice of these students is still very correct. After all, at such a difficult time, it can really inspire people by shouting and cheering. After all, many people are very wronged to be locked up in school. Today we will discuss this matter.

first, what is the current local infection situation? Judging from the data released at present, the number of people infected with COVID-19 epidemic in Dalian is still rising continuously, mainly because there are more floating people in this area and the infection is mainly concentrated in some dense places in the previous increase. So at that time, many people were infected, especially some asymptomatic infected people.

second, the source has been found. If you want to solve the spread of COVID-19 epidemic, you must find its source, because it costs the least, and at the same time, it is the fastest to solve it. Judging from the latest news released by Dalian, during the spread of Covid-19 this time, the cases were mainly concentrated in Keqiang Food Company and the nearby university town, and the reason for this is mainly because it imported a lot of frozen food.

third, why did it spread so fast this time? Judging from the current transmission speed, it has actually passed the peak period, and has now entered a stable period, which is generally controllable. This is a very good signal for the prevention and control of COVID-19 epidemic in Dalian. It proves that in this epidemic prevention and control work, our efforts have not been in vain. The reason why the spread speed is relatively fast is mainly because this time it belongs to Delta mutant, and its concealment is very strong, which can be hidden in people's bodies for a long time without attack.
