In this paper, we comparatively analyzed the data on initial actions and situations of the major European countries related to COVID-19. As a result, it has become clear that government policy and medical system in each country have a significant impact on the number of infections person and dead person. It has also been revealed that lockdown content and timing will affect the spread of the infection. Lockdown should be implemented more strictly before the spread of infection. As for the medical system, it became clear from the data that a full medical system would lead to the recovery of patients. And more, early PCR tests are more effective. It should also be known all over the world that it is important to conduct antigen tests as soon as a new type of virus will occur.
