Fighting the Novel Coronavirus Pneumonia is an urgent task in China and a major concern in the world. As the core of public health events, the answer to the "severity of the epidemic" is the first question to be faced by all walks of life. Based on the data, this paper discusses the impact range and spread trend of the epidemic. In view of the severity of the epidemic, the difference of contact rate, infection rate, diagnosis rate, cure rate and fatality rate in different stages and regions was measured by comparative analysis. Furthermore, the significance and suggestions for multi-scale assessment of the epidemic severity are put forward.
