ABSTRACT

The world is still affected by COVID-19, and the number of infected people is still increasing. Although scientists have developed vaccines, more and more mutants have been discovered around the world. This makes the prevention and treatment of COVID-19 very difficult. In this paper, we discussed the policies adopted by countries that have adopted hard control policies in response to the COVID-19, such as China and New Zealand, and their contribution to the rapid containment of COVID-19. As well as the policies are taken by some countries that implement soft control policies, such as America, and their benefits to people who are experiencing this epidemic, including reducing psychological pressure, economic pressure, and protecting privacy. Finally, we also discussed that the countries actively adjust their policies according to the epidemic's development stage. For example, the United States is transitioning from soft control to hard control. We hoped that all countries could make timely adjustments and choose appropriate prevention and control policies by understanding the advantages and disadvantages of hard and soft controls.
