The number of confirmed cases in the United States itself is as high as 6 million, and the mortality rate is close to 200,000. In this case, the epidemic in the United States is actually out of control. Obviously, it is very unrealistic to resume classes without controlling the epidemic, and the consequences will only get worse and worse. Now the epidemic in the United States looks very serious and the situation is not optimistic.
The epidemic spread in many colleges and universities in the United States, and students got together. If the prevention and control is not effective, it is possible that only one person will infect ten, and ten will infect one hundred. Because of the campus epidemic, the United States has just resumed classes, and it has urgently stopped resuming classes. However, even a few short days have caused very serious and even irreversible consequences.
The reason why the epidemic spread rapidly in American universities is that American college students have no awareness of prevention and control and are still shouting slogans of freedom and human rights. Many American students love parties and parties. They are very resistant to wearing masks. In this state, it is reasonable that the epidemic will spread rapidly. A number of cluster infections occurred in the University of North Carolina just one week after the start of school, indicating that American college students have not fully understood the epidemic, and they still feel that the COVID-19 epidemic is far away from them. In this case, it is safest to start school only if there is a vaccine in the epidemic or if all group immunization is completed. Besides, the only way for American universities to avoid the spread of the epidemic is to take online classes at home.
